6/103

Monitoring & Evaluation

Monitoring = evaluation'The critical assessment, in as objective a manner as possible, of the degree to which a service or its component parts fulfilsstated goals '

6


7/103

Why evaluate? Applies to any strategy, policy, plan or action,

not just highways Have we made a positive difference?

Success or failure? Quantifying - how successful? met targets? Have we been overambitious?

Job done, tick isnt enough Continual improvement learn from

successes and mistakes Helps to prove vfm or secure (or retain)additional funding / support

But, its not easy!

7


8/103

Why is this so hard?

Often a very fine line between success & failure Success can be all things to all men

What constitutes success can be different based on who isasked & what their objectives / agenda are! (who is the client?)

Have we identified the problem correctly? Robustness and confidence in results needed

What are we measuring?

Data isnt always (readily) available or reliable What should be our baseline?/when do we measure?

Nature of road crashes

8


9/103

Challenges & issues

Data (availability, currency, accuracy, under-reporting etc.) Nature of crashes (rare, random, multi-factor) Regression to mean

KPIs / what is success? (what to collect?) Sample sizes? Coping with evaluation of multiple measures Crash migration / crash type changes Resources / responsibilities / funding !

9


10/103

Wider (Strategic) Evaluation

not a specific type of RSA

audit of the auditors

review quality of RSA findings

review client responses

review whether client responses get implemented

assess what safety benefits are actually gained on auditedroads and projects

Capacity and Capability Building

Sharing knowledge & learning from each other is vital Because together we have the combined

KnowledgeSkills

Experience


15/103

How Do We Achieve It?

Forums/conferences/workshops Networking Knowledge Transfer (training) Staff secondments/exchanges

Partnerships / MoUs Guidance documents / toolkits Centres of Excellence Aid agency funded Consultancy commissions Importance of keeping things practical & including local

knowledge

15


16/103

RSA Specifics

Important considerations in building RSA capability: multi-disciplinary approach to road safety concept of auditor independence qualification process for auditors evaluation of audits: cost/benefit comparison audit regulations and legal consequences possibility of a universal checklist

development of an audit database audit procedures in emerging countries

Tools to Assist RSAs

34


35/103

Road Safety Audit Toolkit

The Road Safety Audit Toolkit is a free on-line tool to assist Australian and New

Zealand road safety practitioners to: undertake Road Safety Audits

(at any stage of a project)

document findings

manage and keep track of members in an audit team

provide a well-documentedassessment of issues andassign priority to each

generate a RSA report

browse jurisdiction references

reproduce the Austroads checklists for use in the field

35


36/103

36

Checklist questions

Users are stepped through the checklist questions for the selectedstage of the Austroads Road Safety Auditing process.


37/103

37

Reports

Three report typesmay be generatedby the system:

Detailed auditreport bycategory

Detailed audit

report by priority Corrective action report


38/103

FHWA (USA) - RSA Software

Iit is a tool for assisting with the completion of RSAs facilitates members in the collection of information as they

proceed thorugh RSA process

40/103

Identifying Existing Sites To RSA

needs to be strategically managed at the network level

initial phase (network may have never been audited before) use network assessment tools, such as iRAP or routine RSA Rolling program, all NHs every xx years ?

existing road RSA protocols, &/or thematic RSA, as needed

audit effort should be proportional to assessed risk and inresponse to data-driven/risk-based analyses and/or

community concerns link into ADBs road safety pipeline

Large Scale Existing RSA Programs

A few potential issues: resource intensive particular care with handling outputs -

reports and deliverables! will generate lots of data Intensive mitigation and follow up programs

likely to be required

Dont bite off more than you can chew

Be Careful !

Rolling programprobably better than abig bang

While tempting, theworks burger can be

bad for your networkshealth !

Some Background To The Scheme

2nd

of many schemes on Highway 4 in this district Ch. 157 500 - 166 200 km (8.7 km) Phetchaburi to Lat Tha Sala Project purpose - to by-pass Petchaburi and:

to increase access to services to meet road user / traffic demand for road (now and some future

proofing) local and through traffic (inc. local temple) & mix of traffic (buses, cars, two wheelers, pedestrians etc.)

to enhance the efficiency of road transport to the south to increase safety for road users to minimize the impact on residents near the highway and the

environment as a whole.

Design Audit A Recap

We are considering:- land uses/trip generators- traffic management/conflicts- road users:

- buses- pedestrians- cars- motorcyclists

- bicyclists- think about issues which may occur at night?

Project Briefing

Project Briefing

Road refurbishment project in Kerala, India Focus on provision for vulnerable road user

groups and specifically, signs and markings

Traffic data: AADT = 11,516 and growing rapidly (Kerala PWD) assume moderate pedestrian and bicycle flows and

high motorcycle flow (60% of total flow)

estimated 85th percentile operating speed 70km/h

Findings and De-brief (what did we learn?)

77

What Did The Auditors Note (1)?


78/103


Road goes through residential & commercial areas (KalanadVillage) with no footpath provision on either side

No bicycle or motorcycle facilities 3 no. 3-leg (T) intersections included, but no turn lane

provision or signalisation 4 no. marked unsignalised pedestrian crossing, but only one

raised (incorporating a speed reducing feature). Likely thatmotorised vehicles will not give way to pedestrians

Two pedestrian crossings (Ch. 6+900 and 7+000) are closeto intersection & on a curve (forward visibility may be limited)

78



79/103


Grade separated or signalised crossings (or at very leastpedestrian refuge islands) could be considered if speedscannot be reduced.

No traffic calming measures proposed (apart from the singleraised pedestrian crossing)

Median is centre line only, therefore head-on crashesbetween opposing flows can be expected mitigate withcentral hatching as minimum treatment, but physical median(kerb or barrier) preferred and would give good safety return

With AADT growing increasing capacity may also producesafety benefits & reduce hazardous overtaking manoeuvres

79



80/103


No crash barrier at bridge parapet or culvert head wallstherefore roadside hazards present Posts and trees close to road edge, with proposed widening

these will remain roadside hazards unless removed/protected

Ensure provision of paved shoulder with width >1m Consider raised profile edge markings (possibly rumblestrips) effective low cost treatment

Warning signs provided for intersections and curves, but

possibly located to close to the hazard to provide adequatedriver reaction time

Remember: Avoid tunnel vision, think W I D E Trust first impressions !

Entry and exit slip roads, as well as main body of intersection

Think about manoeuvres for approaches/departures All road users incl. pedestrians, cyclists, motor

cycles, public transport, others(?) Day and night issues

What Sort Of Issues ShouldYou Have Picked Up ?


97/103

You Have Picked Up ?

General issues: Deficient sight lines Poor road markings Lack of pedestrian refuges (Poor lighting at night)

Specific issue:

Approach operating as a one-way dual carriageway for traffic travelling away from the intersection
