Heavy Vehicle Charges Issues Discussion Paper December 2011 iii
Foreword
Since the early 90s – when the Inter-State Commission first proposed to replace different state-based heavy vehicle charges with a national system based on cost recovery – reform has been a difficult but important journey. The journey has delivered important improvements. The industry “pays its way” – no more, no less. Modular charges no longer penalise operators who want the flexibility to use their prime-mover in a semi, B-double or road train combination. Importantly, cost recovery has facilitated significant investment by governments in roads and bridges for a new generation of B-doubles and high productivity trucks. While the charges system is relatively simple to administer, it also has its limitations. For example, heavy vehicle charges are based on average use (kilometres and mass). This report acknowledges that higher A-trailer charges have particularly impacted some operators who use low mileage and/or multiple A-trailers. In the longer-term, CoAG‟s reform agenda will consider a move to more direct pricing of heavy vehicle use. It is, therefore, important to ensure policy reform proposals developed today do not undermine agreed longer-term goals for improved freight efficiency. The National Transport Commission takes its responsibility for recommending national charges very seriously. This year NTC staff have travelled the country listening to operators and industry groups. We thank those operators for taking time from their business – often travelling some distance – to tell their story. The analysis of the options, therefore, is informed by good public policy, a sound evidence base and a genuine desire to address industry issues as quickly as possible. We encourage the industry and community to participate in the consultation process which will inform the final recommendations to Ministers in February 2012.

Executive summary
Australia has seen significant productivity, safety and efficiency benefits since the introduction of national charges in the early 1990s. Uniform charges prevented “forum shopping” across borders and supported the recovery of heavy vehicle road wear costs.
Initially, B-doubles were collectively charged less than the damage they imposed on the road network as they were considered a safer alternative to road trains. Since the late 1980s, governments have made significant investments in a separate national network for B-double combinations. Now nearly half of Australia‟s freight-tonne-kilometres are carried by B-doubles.
Following a Productivity Commission recommendation in 2006, the Council of Australian Governments (CoAG) directed the Ministerial Council ensure that each heavy vehicle class paid its way. This was considered an important “building block‟ for longer-term pricing reform.
When the most recent methodology for calculating charges was developed by Transport Ministers in 2007, industry also wanted modular charges to facilitate greater fleet flexibility. As a result, a separate charge for the lead trailer in B-doubles, known as A-trailers, was introduced. As A-trailers travel high kilometres on average, it attracts a higher charge, leading to concerns raised by some parts of industry, particularly those who use their A-trailers infrequently, or use multiple A-trailers (eg: B-triples).
NTC began investigating industry concerns in May 2011 and established a working group to develop options. In November 2012, Transport Ministers requested that options for addressing the A-trailer pricing concerns be considered and presented to them in February 2012.
Updated data and a more robust methodology for calculating the road wear of the different types of heavy vehicle is being considered as part of this process.
The NTC has identified four options for consultation:
Option 1: Use updated ESA cost allocation values to recalculate charges
Option 2: Introduce a standard trailer axle charge for all vehicle configurations
Option 3: Increase the RUC share of cost recovery and reduce registration charges
Option 4: Use updated ESA values, apply an unsealed road discount to B-triples and increase the share of RUC cost recovery.
Under each of the four options, two scenarios have been assessed; A, and B. Scenario A refers to an annual adjustment being added to the recalculated current 2011/12 charges, while scenario B refers to a combined approach where 2012/13 charges are calculated consistent with the relevant option but incorporating the input data for the annual adjustment (i.e. 2010/11 expenditure and 2008 usage data) so that an additional adjustment using the formula would not be required on 1 July 2012.
These options have been assessed against five key objectives- quick implementation, better B-triple/double road train pricing relativity; national consistency; minimising revenue change; and adherence to COAG Pricing principles.
The option identified as the preferred option, 1b, appears to achieve the best prospects of meeting these objectives in a timely fashion. It also upholds CoAG‟s pricing principles which provide the foundation for transitioning heavy vehicle charges from averaging to a methodology that more accurately reflects vehicle use and road damage.
Given the timing, there was an opportunity to also integrate the public consultation on the related issue of the annual pricing adjustment – the adjustment factor employed each year to ensure heavy vehicles continue to pay their fair share of road costs through registration and fuel charges.
Following several natural disasters across Australia, including flooding in early 2011, governments have funded a significant road and bridge reconstruction program. NTC proposes that this recovery expenditure is excluded from the adjustment process.
The options identified in this report will be subject to a consultation process which will close on 30 January 2012. Following this process NTC will report back to SCOTI on all options and recommending one option for implementation by 1 July 2012. NTC will also provide Ministers with advice on the treatment of the annual adjustment at this time.

1. Introduction
1.1 History
Since 1992 NTC has recommended heavy vehicle charges to the Australian Transport Council (ATC). The charges have taken the form of a fuel based Road User Charge (RUC) and fixed registration charges for every prescribed vehicle classification. The primary objective of the charges has been to ensure that, in aggregate, heavy vehicle charges fully recovered the expenditure on roads allocated to heavy vehicles. Historically B-doubles benefited from significant discounts. This was justified on the basis that the B-double was a much safer and more productive vehicle and should therefore be encouraged.
1.1.1 A new charging framework
In 2007, COAG outlined a new price reform agenda which included, as a first step, undertaking a new heavy vehicle charges determination. COAG was responding to a Productivity Commission Inquiry which verified NTC‟s charging models and also found that heavy vehicles, at the time, were no longer recovering their share of expenditure in aggregate and that significant cross subsidies existed within the charging framework.
As part of the new agenda, COAG required the following:
“ATC direct the NTC, in developing its Determination, to apply principles and methods that ensure the delivery of full cost recovery in aggregate, further develop indexation adjustment arrangements to ensure the ongoing delivery of full expenditure recovery in aggregate and remove cross-subsidisation across different heavy vehicle classes, recognising that transition to any new arrangement may require a phased approach” (COAG 2007).
In addition, the ATC required that charges should not over-recover costs.
In order to achieve these new requirements, as well as ensure modularity of the heavy vehicle fleet, NTC recommended a new charging framework that allowed flexibility of vehicle components to make up any legal combination without the requirement to re-register the components to achieve marginal cost recovery. The new element to the charging framework was the introduction of differentiated trailer axle charges, which differed by type of trailer and axle groupings. The charges were not intended to recover the specific costs of the component (i.e. trailer or prime mover). However, when vehicle components were coupled together they ensured marginal cost recovery of the vehicle configuration.
The new charging framework included the introduction of a considerably higher charge for the lead trailer of the B-double configuration known as the “A-trailer” by industry. The B-triple configuration also faced a significant charge with two lead trailers included in the configuration. Although the charges were introduced over a three year period to ease implementation, in December 2010 industry expressed the view that the new charging framework was leading to adverse outcomes and should therefore be reviewed.
1.1.2 Annual Adjustment
At the same time that the new charging framework was introduced, the annual adjustment formula was revised.
The annual adjustment was initially created to enable charges to keep up with expenditure.
The original adjustment was created in 2002 and was applied only to registration charges with a ceiling of CPI and a floor of 0% (i.e. charges could not fall and increases were limited to a maximum of CPI). The formula attempted to mimic a determination outcome at the aggregate level by calculating the percentage increase in charges required to recover changes in expenditure from year to year. However, with considerable increases in infrastructure spending and the adjustment being applied only to registration charges this had two effects:
2
1) Registration charges recovered a greater proportion of expenditure
2) Charges began to fall behind cost recovery.
As part of the Determination and to ensure the COAG requirement of on-going cost recovery is achieved, NTC introduced a modified annual adjustment which removed the floor and ceiling and also applied the formula to the Road User Charge (RUC).
In 2009, NTC discovered that the formula did not adequately take into account changes in fleet mix and that as a result, the adjustment could result in an under or over recovery of expenditure. The impact was more pronounced under the new annual adjustment than previously was the case because the floor and ceiling and application to only registration charges had “dulled” such impacts. As this outcome was contrary to the 2007 determination and was an unintended technical omission, NTC received a RIS exemption to modify the annual adjustment to take fleet mix changes into account.
1.2 Current situation: charges issues
1.2.1 The A-trailer “problem”
Following concerns raised by industry and initial findings from an industry initiated “A-Trailer survey”, NTC commenced a review of A-trailer charges in May 2011 to ensure that the charges were not producing unintended consequences. As part of the review NTC consulted with industry operators around the country and also established a “Solutions Working Group” to consider the issues raised and potential solutions to address the issues.
The review concluded the following:
1. The impact of cross subsidisation within the vehicle class has been exacerbated due to the removal of cross subsidies between vehicle classes. Previously the under-recovery of cost was spread across the entire vehicle fleet whereas it is now contained to the vehicle class. As the charge for A-trailers is relatively high, there is a greater impact for operators of vehicle classes which face this charge and operate at low mass or low mileage.
2. B-triples are being disadvantaged compared to double road trains as they are limited to the road train network (which has a high proportion of unsealed roads). The charge reflects a 2007 CoAG commitment to a wider national B-triple network that has yet to be realised. Road trains receive an unsealed road discount of around 30% to take into account the lower expenditure associated with unsealed roads.
3. New research commissioned by NTC/Austroads in 2009 showed that the ESA values used to allocate pavement related costs in the 2007 Determination did not accurately reflect more current road use. This had the impact of over-allocating costs to the heavier end of the fleet.
The impact of these issues is unclear. Registration figures were somewhat unreliable due to the lag in flow on impacts and the transitional nature of implementation of charges. Further, manufacturers indicated a broader decline in sales (i.e. not limited to A-trailers). NTC concluded that whilst there was not strong empirical evidence that there was a significant impact on B-doubles, there was anecdotal evidence of an impact for B-doubles and of a more significant impact on B-triples.
Whilst it was difficult to find evidence that the A-trailer charge in its own right was significantly impacting B-double demand, the report found that these issues were probably exacerbating the impact industry was facing as a result of the general economic downturn. This appeared to be confirmed by a general decline in vehicle manufacturing of vehicles not in the mining sector. NTC did consider that there may be substitution issues resulting from charges and that this would have an adverse cost particularly in terms of road maintenance and safety. In addition, the discrepancy between WA charges and SA created an opportunity for SA operators to re-register their vehicle in WA and receive a $10,000 discount for a B-triple combination. The opportunity to do so, however, appeared relatively limited due to registration requirements.

Following receipt of NTC‟s advice and growing concern from industry, SCOTI directed NTC to present it with options in February 2012 for consideration.
This report details the proposed options that will be presented to SCOTI and details how the charges have been calculated as well as the high level impacts.
1.2.2 The impact of natural disasters
In 2010, much of the country experienced significant natural disasters – particularly flooding. As a result, many governments were required to undertake considerable road reconstruction activity. Some of this activity has been funded through insurance. Some is being funded through a newly created flood levy which was created specifically to fund reconstruction activity. Whilst the levy is being collected only in the 2011/12 financial year, it may be take a number of years for it to flow through to road expenditure.
NTC identified that this would be an issue early in 2011 following industry concerns raised during the consultation of the 2011–12 annual adjustment for the RUC. Whilst NTC did not believe the issue relevant for that annual adjustment (as the expenditure related to non-flood years), it did believe it would be a relevant issue for 2012–13. As such, NTC held a government workshop in May 2011 to discuss the issue and amended its template for the 2010–11 government expenditure return so that governments could identify reconstruction activity funded through other sources.
NTC is of the view that reconstruction activity funded through insurance and the flood levy should be excluded from the annual adjustment cost base for the following reasons:
Those governments which are insured have advised that they have claimed the cost of their premiums through the heavy vehicle charges. Therefore industry has already paid their share of insurance cost. Recovery of reconstruction activity through charges that is then claimed through insurance would constitute a double recovery.
The flood levy has been created specifically for reconstruction activity. Again it would be double counting if jurisdictions were to claim this expenditure through charges as well as through the flood levy fund.
NTC is of the view that the inclusion of these items would breach the ATC requirement of no over-recovery. Further, the exclusion of this expenditure is consistent with the Determination approach to exclude other sources of revenue in determining heavy vehicle charges to ensure there is no double counting. For example, NTC excludes an estimate of the contribution of council rates towards road expenditure in the charges determination models.
As this would not be a departure from current practice of excluding revenue from other sources, NTC has obtained a RIS exemption to make this adjustment to the annual adjustment formula.
This document will consider this approach as part of the consultation process in advance of providing advice to Ministers in 2012. It is important to note that this report seeks only to consult on the approach to the modification. NTC is currently undertaking a verification process with governments to ensure accurate reporting of reconstruction activity funded through other sources.

2. Current Approach: Status Quo
2.1 Pricing principles
Historically the NTC has been guided in the development of its heavy vehicle charges recommendations by a number of principles which are endorsed by Transport Ministers. In the 2007 Determination the guiding principles were prescribed as:
“National heavy vehicle road use prices should promote optimal use of infrastructure, vehicles and transport modes.
This is subject to the following:
full recovery of allocated infrastructure costs while minimising both the over and under recovery from any class of vehicle
cost effectiveness of pricing instruments
transparency
the need to balance administrative simplicity, efficiency and equity (eg impact on regional and remote communities/access)
the need to have regard to other pricing applications such as light vehicle charges, tolling and congestion.”
The ATC principles provide a degree of flexibility where trade-offs are able to be made between the principles.
As discussed in section 1.1.1, COAG introduced additional requirements for heavy vehicle charges. These are:
On-going cost recovery in aggregate
The removal of cross subsidies between vehicle classes,
The COAG requirements offer less flexibility in the calculation of charges.
Both the ATC and COAG principles are standing principles until the relevant authority changes them.
2.2 Current methodology
The current charging framework is based on a Pay As You Go (PAYGO) cost base. The cost base is calculated on the principle of full cost recovery of both capital and operational historic road expenditure in any given year. In reality, however, an averaging over time approach is applied to both cost estimation and usage so that there is effectively a lag in recovery, The averaging (over seven years) is intended to moderate fluctuations and volatility in both expenditure and usage so that there is greater consistency in charges from year to year.
The cost base for charges is calculated using annual arterial road expenditure figures (provided by each State and Territory every year against 14 cost categories) as well as local government road expenditure reported to ABS. These figures are published in the NTC annual report and include any contributions made by the Commonwealth. Expenditure that is recovered through other sources is excluded from the cost base. This includes an “amenity” amount from local government which is recovered through local rates. As a result only 25% of urban local and 50% of rural local road expenditure is included in the NTC cost base. This takes the total cost base from $16.2b to $11.6b (see appendix A).
The remaining figure is known as the allocable cost base which is then allocated across the entire vehicle fleet to derive the amount to recover by each vehicle class.
5
Four key parameters are used to allocate costs in each cost category to each vehicle class:
Average Gross Mass (AGM)
Equivalent Standard Axles
Passenger Car Units (PCU)
Vehicle kilometres travelled (VKT)
The cost allocation matrix is presented below:

The cost matrix determines the attributable costs by vehicle class as well as the common costs by vehicle class (see appendix A). Attributable costs are those that are directly related to road usage (e.g. road maintenance).
The cost by vehicle class is converted into the RUC and registration charges by dividing by Survey of Motor Vehicle Usage (SMVU) usage data. NTC uses an „average‟ data point by using the mid-point year of the seven year average as the representative usage year. Fuel consumption and vehicle numbers are used to derive the charges and a 1.5 multiplier is used to factor in space trailers (i.e NTC assumes there are 50% more trailers than in any given trailer combination). The
6
combination of the RUC and registration charge for each vehicle class must ensure recovery of at least attributable costs.
The split between the RUC and registration charges (currently 62%:38%) are largely historical in nature and reflect revenue shares between the Commonwealth and states/territories at the time of the introduction of national charges.
To ensure the modularity of the vehicle components, the amount to recover is spread over the various component pieces of the vehicle configuration so that they are able to be used in different configurations whilst still meeting the pricing principles.
Industry has argued that the resulting charges are not intuitive in nature as they do not reflect the payload capacity of the trailer. This argument highlights the difference in the way operators‟ value freight transportation and the requirement that vehicle configurations (not components) recover costs.
2.3 2012/13 Annual Adjustment
NTC has now calculated the annual adjustment to take effect on 1 July 2012. Using the existing formula (and including the technical adjustment for fleet mix changes) the adjustment is 6.7%. The adjustment is higher than normal due to the considerable increase in road construction costs over the past 12 months. This is captured through the Bureau of Infrastructure Transport and Regional Economics (BITRE) Road Construction and Maintenance Price Index (RCMPI) which the annual adjustment uses to inflate nominal expenditure figures in the seven year average. The index showed road construction costs increased by 11 points over the past 12 months which reflects a percentage change of 7.2% from the previous year. This is considerably greater than the previous year which showed a percentage change of 1.4%.
The annual adjustment discussed above currently includes reconstruction expenditure which arose from natural disasters in 2010/11. As discussed in section 1.2.2, NTC proposes to recommend to SCOTI that a further technical adjustment should be made to the annual adjustment to deduct reconstruction activity funded through other sources such as the flood levy and insurance. NTC has made an initial estimate of the adjustment based on initial information provided by governments in relation to their reconstruction activity. However, this number is likely to change as governments are able to more clearly identify how much of their reconstruction activity is to be funded from other sources.
This results in an estimated modified annual adjustment of between 5.4% and 6.7%, subject to verification of data.
For the purpose of calculating charges for consultation, NTC has used the 5.4% figure. The calculation of the annual adjustment is contained in appendix F.

3. Options
NTC has identified four key options which seek to address the issues raised in section 1.2.1. The options are:
Option 1: Use updated ESA cost allocation values to recalculate charges
Option 2: Introduce a standard trailer axle charge for all vehicle configurations
Option 3: Increase the RUC share of cost recovery and reduce registration charges
Option 4: Use updated ESA values, apply an unsealed road discount to B-triples and increase the share of RUC cost recovery.
Under each option NTC has considered how the annual adjustment could be treated. There are two scenarios:
a. A separate approach where 2011/12 charges are recalculated consistent with the relevant option and the annual adjustment derived using the annual adjustment formula is then added to the recalculated charges; or
b. A combined approach where 2012/13 charges are calculated consistent with the relevant option but incorporating the input data for the annual adjustment (i.e. 2010/11 expenditure and 2008 usage data) so that an additional adjustment using the formula would not be required on 1 July 2012.
The two different scenarios result in different charging outcomes for each option as the first approach uses a formula which estimates the outcomes of the charges models and applies a blanket increase across all charges whilst the second approach reflects the actual outcomes of the charges model where charges better reflect actual cost allocation by vehicle class.
The status quo is the current charges + 5.4% (i.e. what would occur if no change was made to charges).
3.1 Principles for assessing options
The following assessment criteria have been identified to assess each option:
Quick implementation – to be implemented by 1 July 2012
Better B-triple/double road train pricing relativity
National consistency – the preparedness of each government to implement the option
Minimising revenue change for each government from what they would otherwise receive
Adherence to existing pricing principles
PLEASE NOTE: The numbers presented for analysis in this document are for consultation purposes only. They will change over the consultation period as issues are raised and resolved. However, they give a clear direction of the movement and magnitude of change. NTC will continue to work with industry as numbers are updated.
3.2 Option 1 - Updating ESA values in the cost allocation models
3.2.1 Description:
Under this option, the status quo methodology is applied with an amendment to the Equivalent Standard Axle (ESA) values in the cost allocation matrix.
8
ESA values are used to apportion road wear costs that a particular vehicle class is responsible for. The allocation of these costs contributes to identifying the “attributable” or marginal cost of each vehicle class.
The 2007 determination utilised ESA research completed by ARRB (Styles and George 2005). Whilst this work represented the most up to date research at the time, the authors identified a number of limitations in the methodology:
1. An average Gross Vehicle Mass (GVM) approach was used instead of a distributional approach – from a statistical point of view, a distributional approach methodology delivers a more accurate representation of the WIM data set.
2. Data was missing from key jurisdictions – The current sample of weigh-in-motion (WIM) data does not include observations from Western Australia.
3. Data was only available for a limited number of vehicle types – ESA values are only available for a limited number of vehicle types which are considered in the current PAYGO charging model.
4. Inaccurate logarithms used in deriving ESA values for certain vehicle types – For the vehicle classes that an ESA value was not observed, logarithms were used to estimate an ESA.
5. Data was significantly outdated – The WIM data that used in the 2007 determination used 1998 to 2000 data.
In 2008 ARRB, as part of a project undertaken in conjunction with Austroads, commence work to recalculate the ESA values based on a more comprehensive data set and across all heavy vehicle categories. The research, completed in 2009, addressed each of these data limitations listed above as a means to increasing the accuracy and confidence in the ESA estimates (see appendix D for a summary explanation of how the ESA values were derived by ARRB).
NTC has used this research as the basis for the new ESA values incorporated in this option. However, it has amended the values to ensure better consistency with the current charges framework. Specifically it has asked ARRB to ensure the data is representative in nature (the original work had a high Victorian representation), and overloading has been limited to 10% (consistent with current practice and reflecting a general accepted error factor in WIM data).
A continued recognised limitation of the research is a bias in the ESA values of some vehicle types due to the difficulty in identifying certain vehicle classes at different mass levels in the WIM data. However, these limitations are consistent with the limitations of the current ESA values. In addition, industry has questioned whether it is appropriate to include HML data limits in the methodology as this is inconsistent with current practice. NTC will further consider this issue during the consultation period.
Despite the known limitations, NTC believes the research represents a significant improvement for industry in the estimation of ESA values. The work essentially shows that the lighter end of the heavy vehicle fleet is having a more significant impact on the road network than the previous approach had estimated and that there are a number of non-articulated vehicles which are now not recovering their attributable costs. This would appear to be consistent with views expressed by articulated vehicle operators who have argued that there is vehicle substitution to less productive and less safe vehicles due to lower registration charges for these vehicles.

3.2.2 Assessment against criteria
Table 2. Option 1a, and 1b assessment.
Criteria Option 1a (2011/12 charges + annual adjustment formula)
Option 1b (2012/13 charges no annual adjustment formula required)
Quick implementation
A paper could be prepared and delivered to ministers for decision in February 2012. Implementation would require that jurisdictions replace the current heavy vehicle charges with the new numbers – this is essentially equivalent to the implementation of the annual adjustment. No other change in law is required.

Better B-triple/double road train pricing relativity
The results show the B-Triple registration charge falling by $2,463 to $20,972, and the B-Double falling by $1,284 to $15,273. This is due to a reduction in the lead tandem, and lead tri axle charges by 27%, and 18% respectively. In terms of price relativities, the B-Triple charge of $20,972 still remains approximately double the registration charge of the double road train at $11,986. See appendix B for detailed charges.
The results show the B-Triple registration charge falling by $6,551 to $16,883, and the B-Double falling by $3,152 to $13,404. This is due to a reduction in the lead tandem, and lead tri axle charges by 49%, and 47% respectively. In terms of price relativities, the B-Triple charge of $16,883 is more comparable to the registration charge of the double road train of $12,718. (a reduction in the gap of around 80%) See appendix C for detailed charges.

Minimising revenue change
There is likely to be a moderate decrease in overall State / Territory revenue due to a higher RUC which is required to balance out the reduced revenues accrued via the registration portion of the charge model. NTC estimates revenue shares as in appendix G.

Adherence to Pricing principles
The adoption of this option is compliant with COAG principles as it removes cross subsidies between vehicle classes. As such, OBPRs advice is that this amendment would not require a RIS as there is no change in policy or regulation.

3.3 Option 2 – Standard Trailer axle charge (based on the ATA Proposal)
3.3.1 Description:
Under this proposal, the A Trailer charge would be reduced, with the cost spread across over vehicle classes. There are several sub-options:
a) Introduce a standard axle charge for trailers: this is equivalent to the charges framework that existed prior to the 2007 heavy vehicle charges determination. This approach is administratively simple and is supported by industry.
b) Reduce the A Trailer charge to an “acceptable” level and spread the cost over remaining vehicle components: this maintains a differentiated trailer charge. This approach would only be taken to strike a better balance in terms of revenue impacts.
NTC has modelled the first of these approaches which is based on the proposal the Australian Trucking Association (ATA) has identified as its preferred model. This option results in the reintroduction of a B-double cross subsidy of around $6,000 per vehicle (i.e. on average B-doubles would under-recover their direct impact on the road by $6,000 per annum). This under-recovery would be recovered by other vehicle classes by increasing their charges.
NTC notes that the second approach has an objective of maintaining revenue neutrality in each jurisdiction. However, because each jurisdiction has a different fleet mix this approach would necessarily bring an end to national charges and could ultimately result in nine sets of charges for each vehicle class. In addition to encouraging “shopping around” for the best charges (as was the case prior to national charges being introduced), this would result in additional administrative complexity for the new National Heavy Vehicle Regulator.

Criteria Option 2a (2011/12 charges + annual adjustment formula)
Option 2b (2012/13 charges no annual adjustment formula required)
Quick implementation
This approach would require COAG agreement to change their pricing principles and under COAG processes would be subject to a Regulatory Impact Statement.
NTC estimates a final RIS could be presented to SCOTI in June with implementation on 1 October 2012 (assuming COAG principles changes at its March 2012 meeting).

Better B-triple/double road train pricing relativity
Under this option the registration charges for B-Triples would fall by $7,663 to $15,771, and for B-Doubles, a fall of $4,871 to $11,686. This equates to a fall in both the lead tandem, and lead tri axle charges by approximately 73%.
The option achieves greater price relativity between the B-Triple and the double road train with the gap narrowing considerably. The B-Triple charge under this option
Under this option the registration charges for B-Triples would fall by $8,702 to $14,732, and for B-Doubles, a fall of $5,576 to $10,980. This equates to a fall in the lead tandem, and lead tri axle charges by approximately 74% and 76% respectively.

Minimising revenue change
The majority of the states will experience a material fall in revenues while the Commonwealth will pick up the difference through the increased RUC. Revenue impacts would be neutral if increased RUC revenues are redistributed. This this did not occur NTC estimates revenue shares as in appendix G
There is likely to be an increase in overall State / Territory revenue due to a marginally lower RUC which is required to balance out the higher revenues accrued via the registration portion of the charge model. NTC estimates revenue shares as in appendix G.
Adherence to Pricing principles
This approach does not comply with COAG principles and is inconsistent with the principles underpinning CRRP. It encourages the uptake of vehicles that is in excess of efficient levels and encourages inefficient operation (e.g. Inefficient trailer loading) which has costs to road providers. It may also act as a discouragement for broader investment and access for B-doubles and B-triples as they would no longer be „paying their way‟

It may also act as a discouragement for broader investment and access for B-doubles and B-triples as they would no longer be „paying their way‟
NTC notes that there are other combinations of charges which could be calculated under this model for scenario B and it will work with the ATA on identify the best combination prior to providing its advice to SCOTI.
It should also be noted that the ATA has argued that this option could be made to be compliant with COAG pricing principles if trailers were treated as a vehicle class. However, this is a fundamental change to the vehicle classification system and would require new usage data (that is currently not collected) as well as potentially changes to registration systems. Furthermore, it assumes that the costs that trailers would be required to recover are consistent with what trailers currently recover as a whole. However, there is no data or evidence to suggest this is the case.
NTC is of the view that if this change to the classification system was to take place, it would constitute a significant change and would take some time to implement.
3.4 Option 3 - Change the split between Registration and the Road User Charge.
3.4.1 Description:
This option applies the status quo methodology but increases the share of costs recovered through the RUC. This results in a higher RUC and lower registration charges.
The split between the RUC and registration charges has been historically set and reflects the revenue shares that existed between the Commonwealth and State/territories at the time of the First Determination in 1992. Over time, the share changed in favour of the States/Territories as
12
registration charges were increased by the annual adjustment and the RUC was not. The 2007 Charges Determination set revenue splits between the two charges to reflect more the revenue shares in 2007 (60:40) and took into account the inclusion of enforcement costs in the cost base (which the Commonwealth does not contribute to).
This option increases the RUC share to more historical levels (i.e. 66:34). Whilst this reflects historical shares, it does mean a movement away from revenue shares agreed in 2007. As a result, governments may seek to negotiate a financial agreement to hold them revenue neutral.
This option is limited in its effectiveness due to a limitation in the methodology which requires heavy vehicle registration charges to maintain relativity to registration charges for light vehicles. This is to prevent “boundary” issues where some commercial operators may be given a perverse incentive to use heavy vehicles (e.g. a 2 axle rigid) because it is cheaper than a light vehicle.

Assessment against Criteria

Quick implementation NTC is of the view that this option is unlikely to require a RIS as current commonwealth legislation provides a process for increasing the RUC. If a RIS is required, the timeframes would be similar to the timeframes outlined under option 2.

Better B-triple/double road train pricing relativity
B-Triple registration falls by $3,336 to $20,098 and the B-Double by $2,087 to $14,470. This equates to a fall in both the lead tandem, and lead tri axle charges by approximately 17%. Price relativities between the B-Triple and the Double Road Train are not materially reduced by this option, with the B-Triple still costing approximately double that of the Double Road train.
B-Triple registration falls by $5,773 to $17,661 and the B-Double by $3,446 to $13,110. This equates to a fall in the lead tandem, and lead tri axle charges by approximately 30%. Price relativities between the B-Triple and the Double Road are slightly better under this option, however the B-Triple will still cost approximately 60% more than that of a Double Road train.

3.5 Option 4 Update ESAs, B-triple Discount, and Increased RUC
This is a combination approach which combines options 1 and 3 and also includes an unsealed road discount for B-Triples similar to the discount which is applied to road trains. The discount reflects the fact that these vehicles typically operate on the road train network which has a large proportion of unsealed roads. Unsealed roads have lower costs attributed to them.
Like its component parts, combination Option 4(a) is in keeping with the COAG pricing principles. It would not need a RIS and could be implemented by 1 July 2012. The combination of the options provides greater flexibility in adjusting the level of current charges whilst still meeting the attributable costs for each vehicle class.

Better B-triple/double road train pricing relativity
Under this option the registration charges for B-Triples would fall by $6,723 to $16,712, and for B-Doubles, a fall of $3,794 to $12,762. This equates to a fall in both the lead tandem, and lead tri axle charges by approximately 39% and 45% respectively. In terms of revenue, the states as a whole would receive less revenue, with some states seeing a material decrease.
The option achieves greater price relativity between the B-Triple and the double road train with the gap narrowing considerably. The B-Triple charge under this option would be $16,712 compared to a Double road train at $11,113.
Under this option the registration charges for B-Triples would fall by $7,908 to $15,526, and for B-Doubles, a fall of $4,240 to $12,316.

The most notable increase in registration charges will impact the 4 axle rigids, who would see their registration charge increase from 1.7% of total cost, to 5.0% under option 1a, and 4.3% under option 4a. However, this increase returns the charge for those vehicles to a level consistent to pre-2007 Determination levels. In terms of decreases, the most notable reduction in charges will impact the B-Triples, who would see their registration charge fall from 9.3% of their toal cost to 6.7% under option 2a and 4a.

4.2 Government Revenue Impact
4.2.1 Revenue impacts under Scenario A
The following graphs depict the expected impact each option (under scenario A) will have on both State and Commonwealth revenues; the calculation of revenues assumes the old cost base inflated by 5.4%, and vehicle numbers derived from the SMVU, not actual registration data. The status quo under this scenario reflects estimates of revenues from 1 July 2012 for each government should no change be made to charges.
Figure 3: State/territory revenue impact under Scenario A
Option 1a will enable all states and territories to maintain their existing revenue share. Option 2a will see NT and WA receive additional revenues, whilst the others will receive less. Both options 3a and 4a will see all states and territories losing revenue to the Commonwealth with the increased RUC.

5.2 Preliminary conclusions
NTC‟s preliminary recommendation is for SCOTI to adopt option1b. This option is compliant with charging principles and consistent with the COAG Road Reform Plan, is able to be implemented in a timely fashion without a RIS and results in a significant reduction in the A-Trailer charge and the gap between B-triples and double road trains. This option also eliminates the need to undertake a separate annual adjustment process using the annual adjustment formula in 2012/13.
Option 4b is also an attractive option and has the additional benefit of reducing the impact of cross subsidies within the vehicle class. However, this option has fiscal complexities with states and territories likely to seek the redistribution of the additional RUC revenues. This may compromise the timely implementation of this option. NTC notes that if this was able to be resolved, it would this option would enable governments to be held revenue neutral.
Option 2 is a viable option. However, NTC is of the view that a RIS would be required to deliver this option as it is a more fundamental charge in the charging framework and reverses the outcomes of the 2007 Determination. COAG would be required to soften their pricing principles to underpin a RIS. The RIS requirements compromise the timeliness in delivery of this option.
Options 3 does not deliver a reasonable outcome and is therefore not considered to be a viable option.
5.3 Next steps
NTC will commence a consultation process on these options on 19 December 2011 and seeks written submissions on the options by 30 January 2012.
NTC will submit its final report to SCOTI by the end of February 2012 with the expectation that the preferred option is implemented by States and Territories by 1 July 2012.

Appendix D: ESA methodology
The new research conducted by ARRB seeks to address the data limitations discussed in section
3.2.1 as a means to increasing the accuracy and confidence in the ESA estimates.
This work has been done in conjunction with Austroads and has been reviewed through the assets
taskforce.
The following is a high-level overview of the steps taken to prepare and process the data, and
generate the ESA values for each vehicle class.
1) Processing of the raw data:
a. The raw data is „cleaned‟ and split into 63 separate vehicle categories, using
complex categorisation rules based on axle groupings and separation
b. For each category, grossly overloaded vehicles are removed based on maximum
allowable masses for GVM and individual axle groups (values are dependent on
vehicle category)
c. Categories are condensed into the 22 NTC price allocation vehicle classes, for the
rural and urban components of each jurisdiction (approx. 315 data sets)
2) Processed data is used to derive ESA values:
a. An adjusted national data set is recreated based upon the distribution of the
jurisdictional (and where possible, the urban-rural split) Vehicle Kilometres
Travelled (VKT) data. Separate checks and processes are adhered to where a
particular jurisdiction and/or urban-rural split has insufficient sample size.
b. Further processing is undertaken to remove statistical outliers based upon the
impact they have on the overall data set („robust regression‟)
c. Curves (equations) are fitted to the data set. Checks are conducted to ensure the
fitted equations are closely representative of the data.
d. Several ESA values are generated from the fitted equations using different
methods
3) Removal of overload data.
The original ARRB / Ausroads report included WIM observations for up to 100% overload
of a vehicle‟s GVM limit. However, for charges purposes the NTC, on the advice from
ARRB has only included overload data for up to 10% of a vehicles GVM limit. This 10%
represents an error margin, and is consistent with the 2007 determination. Any deviation in
the 10% overload factor represents a significant change to the charging methodology and
would require the completion of a RIS.
Despite the complex and detailed rules for processing data, there are inherent limitations to using
the WIM dataset, and these limitations can in some instances lead to the miscategorisation of WIM
observations. This issue also existed in the 2007 determination.
40
Appendix E: Method to calculate usage data
SMVU data is used as the source data to calculate the heavy vehicle charges for Determinations and Annual Adjustment purposes. The SMVU data set is acknowledged to be the only data set that provides sufficient level of disaggregation that meets the requirements to calculate the prescribed heavy vehicle charges method.
However, the data set has relatively high RSE‟s (Relative Standard Errors) at the level of disaggregation required by the NTC due to the survey based nature of the information as opposed to an empirical / observation based data gathering method.
To address the issue of statistical variability and volatility, a seven year trend approach is taken to reduce inherent bias should a particular year of data be used. The method uses seven years of historical data to return a line of best fit using a least squares linear regression.
This method has been the approved approach since 2007 for both the Determination and the Annual Adjustment of charges.
However, the NTC has had to adjust this method due to the unavailability of SMVU data in 2008 and 2009. Whilst continuous annual SMVU data was available from 1998 to 2007, due to budget cuts, ABS ceased collecting data for 2008 and 2009. In 2010, the SMVU data collection was resumed and ABS has confirmed that going forward the SMVU data will be collected on a bi-annual basis.
To address the issue of missing 2008 and 2009 data, the trending method has been modified, and a “double trending” approach adopted.
The 2010 SMVU data has been used in conjunction with the data set from 2001 to 2007 to infer the 2008 and 2009 data using a least squares linear regression. In order to do improve the accuracy of this method, the regression analysis has been done for each of the vehicle categories and not just at the overall total values.
After the 2008 and 2009 values are established, the normal trending method as described above is then applied to calculate the 7-years trend value used for the calculation of heavy vehicle charges.
For the purposes of setting charges for 2011/12, the 2008 trend road usage data is used (7 year mid-point).
The “double trending” approach has been independently reviewed by an external consultant, who considered the approach to be an acceptable fix for the missing data.

Appendix F: Annual Adjustment calculations
As per the April 2007 COAG communiqué, one of the responsibilities of the NTC is to apply an annual adjustment to ensure the ongoing recovery of Heavy Vehicle road expenditure in aggregate. The annual adjustment formula, as agreed to by the ATC in April 2010, is documented in the Model Heavy Vehicle Charges Act 2007 (as amended).
The derivation of the annual adjustment factor can essentially be broken down into three distinct steps:
Step 1 Determine the „raw‟ annual adjustment factor
Step 2 Derive the new estimated heavy vehicle cost base
Step 3 Derive the annual adjustment factor – the rate at which charges must increase so that the charge revenue equals the estimated cost base.
The section below outlines the processes involved and calculations undertaken in each of these steps.
Step 1: Derive the „raw‟ annual adjustment factor
The raw annual adjustment factor (RAAF) represents the annual change in the cost base that is
attributed to heavy vehicles. The RAAF formula as outlined in the Act is as follows: Raw annual adjustment factor (%) = road expenditure factor + road use factor
Where the road expenditure factor (REF) =
0.454 x percentage change in rural arterial road expenditure +
0.362 x percentage change in urban arterial road expenditure +
0.119 x percentage change in rural local road expenditure +
0.064 x percentage change in urban local road expenditure
The road use factor (RUF) = –1% When the new road expenditure data is applied to the above formula it generates a REF of 11.4%. When combined with the RUF of –1% the result is a raw annual adjustment factor of 10.4% (refer to the later section on the Road Use Factor for explanation of this).
The figure of 10.4% represents the estimated percentage increase in the heavy vehicle cost base from the previous year.
Road expenditure factors
The road expenditure factor reflects the change in expenditure across the four different road types: rural arterial, urban arterial, rural local and urban local. Arterial expenditure relates to state/territory expenditure, while local expenditure refers to local government expenditure. Federal government financial contributions (such as the Building Australia Fund road projects) are included in both these categories. Furthermore, the calculations are weighted („A‟ factor weights) to reflect the influence of each expenditure type on road costs that should be recovered from heavy vehicles.
1
The „percentage change in road expenditure‟ refers to the change in the seven-year moving average road expenditure – in real dollars. Therefore, the annual adjustment compares a seven-year average of road expenditure for years 1 to 7 against years 2 to 8, with year 8 being the last year of actual expenditure data.
1 The weights are based on data used in the 2007 Heavy Vehicle Charges Determination.
42
Road expenditure
The annual adjustment formula requires that road expenditure figures are expressed in real dollars (which is consistent with the method undertaken in a charging determination). The Bureau of Infrastructure, Transport and Regional Economics (BITRE) Road Construction and Maintenance Price Index (RCMPI) is used to convert road expenditure from nominal dollars to real dollars. Table 1 contains the most recent set of RCMPI values that have been used for the 2012 annual adjustment, the data including revisions to prior years.

Arterial road expenditure
For 2010/11 expenditure, NTC proposes to deduct any reconstruction expenditure that is funded through other revenue sources (eg insurance or the flood levy). The estimated expenditure for that year is shown in Table 14. These numbers are currently being verified by each state and territory and are subject to change.
2 In 2010 the BITRE revised the RCMPI methodology; this included rebasing the index year with 1998–99 =
100.

Applying the road expenditure figures derived in Tables 17 and 20 to the REF formula results in a RUF of 11.4%.
RUF = (0.362 x 17.2785) % change in urban arterial expenditure
+ (0.454 x 9.8253) % change in rural arterial expenditure
+ (0.064 x 3.9576) % change in urban local expenditure
+ (0.119 x 3.5811) % change in rural local expenditure
= 11.4%
Road use factor
The RUF reflects the change in expected road use by heavy vehicles. There are three parts to calculating the RUF:
expected changes in light vehicle travel
expected changes in heavy vehicle travel
expected changes in the number of heavy vehicles.
It is important to capture changes in light vehicle travel when estimating costs for heavy vehicles. If light vehicle travel increases more than heavy vehicle travel, light vehicles will absorb a greater share of the allocated cost and the road costs to be recovered from heavy vehicles will fall.
If the number of heavy vehicles increases, the cost to be recovered from heavy vehicles per vehicle will decrease, assuming the overall level of cost allocated to heavy vehicles remains unchanged.
A RUF of –1.0% was estimated based on a review undertaken as part of the 2007 Heavy Vehicle Charges Determination. This factor acts to modify the overall road expenditure impact in the annual adjustment formula to take account of changing road use by heavy vehicles.
Having derived the various expenditure components of the REF (11.4%) and the RUF (–1%) we are able to add the two components together in order to derive the RAAF. The RAAF associated with the 2012 annual adjustment is 10.4%.
Step 2: Derive the revised adjusted base cost
Step 2 involves using the RAAF to derive the revised adjusted base cost (RABC). The RABC is the estimated heavy vehicle cost base that is be recovered via registration and road user charges in order for heavy vehicle users to pay their share of road costs. The RABC for 2012 is derived by multiplying the RABC from 2011 by the newly derived RAAF.
For the 2012 annual adjustment, the RABC or estimated heavy vehicle cost base is $2,640.65 million. This equals $2,391.89 million, which is the 2011 heavy vehicle cost base multiplied by 1.104 (the 2012 RAAF).
47
Step 3: Derive the annual adjustment factor
The third step involves deriving the annual adjustment (AA) factor. The annual adjustment factor is equal to the percentage change required in both existing registration and road user (fuel charge) revenue required to equate total charge revenue with the updated estimate of the RABC.
AA = (RABC – RR – FR) / (RR + FR) x 100
Where, RR refers to current registration revenue and FR refers to current fuel revenue.
This equation says that the AA factor (expressed as a percentage) is equal to the difference between the updated RABC for the current annual adjustment year and the total amount of existing registration and road user charge (fuel charge) revenue at last year‟s charge rates divided by the total amount of existing registration and road user charge (fuel charge) revenue at last year‟s charge rates (refer to Appendix A for registration and fuel revenue estimates).
For the 2012 annual adjustment year, the value of the AA factor is as follows:
AA = (RABC – RR – FR) / (RR + FR) x 100
Where:
RABC = allocated cost in the current year of $2,640.65 million as derived above
FR = existing RUC revenue based on last year‟s fuel rate = $1,546.62 million. This is based on heavy vehicle fuel use as published in the NTC 2011 Annual Report (Appendix E) of 6,695,337,207 litres multiplied by 2011 RUC of 23.1 cents per litre.
RR = existing registration revenue based on last year‟s registration charges = $957.80 million. This is based on combined heavy vehicle registration revenue of $617.52 million plus heavy trailer registration revenue including spare trailers of $340.28 million as published in the NTC 2011 Annual Report (Appendix E).
AA = ($2,640.65 m – $957.80 m – $1,546.62 m) / ($957.80 m + $1,546.62 m) x 100
= ($136.23 m / $2,504.42) x 100
= 5.44%
This value is then rounded up or down to one decimal place as similarly applies to the raw AA factor. Therefore, for the 2012 annual adjustment year, the AA factor that applies equally to both registration charges and the RUC is 5.4%.
