• Authorized use of Highway Trust Fund cash balances (2001)
• $515 Million– $45 Million for signal improvements– $470 Million for pavement improvements
– up to 10% for economic development
• Benefits include:– Targeted major primary system corridors– Resurfaced & rehabilitated 5,500 lane miles of NC and US
Routes– Helped slow the increase of resurfacing backlog &
pavement needs– Improved highway safety
Senate Bill 1005
• $630 Million *Revised Delivery Schedule– $400 Million by end of 2005– $230 Million from 2006-2007– Budget adjustments impact only delivery time, not
number of projects
• Benefits include:– Reduces resurfacing backlog– Reduces patching costs and shoulder maintenance– Improves pavement markings and markers– Replaces bridges with high maintenance costs– Improves traffic flow and enhances safety

System Preservation
• New line item in maintenance budget• $ 78.6 M• Preserve the highway system by extending the life of pavement, bridge, and traffic features
– pavement seals– bridge painting– pavement marking
• $1 spent today saves $5 tomorrow

Alternate Funding
• TIP Funds– Signal Preventive Maintenance Program
(8,800 Traffic Signals Statewide)
– Intelligent Transportation System/Incident Response Program
– Positive guidance
• HB 1825– Allows SR Construction funds
to be used on paved SRs– Improves functionality, safety,
and condition

Maintenance Operational Improvements
• LED replacement for signal bulbs
• Signal preventive maintenance
• ITS (IMAP) initiatives• Incentive pay programs• DOC litter pickup program• Winter anti-icing operations
• Goals– Move from reactive to strategic/outcome based
– Clearly define mission & expectations for operations
– Develop strategies resulting in improved efficiency, performance, & preservation consistent with the Statewide Long Range Plan
– Develop management tools/systems to measure outcomes & performance
– Management flexibility with accountability
Performance Based Management Initiative
Statewide Transportation Plan
• Purpose– Offers policy guidance
& strategic direction
for NCDOT– Federally mandated– Inventory of 25-year
transportation needs for all modes– Forecast of available revenues– Opportunity to solicit public & stakeholder interest– Outlines long-term transportation investment priorities
• Statewide Tier - Facilities such as Interstates and major Primary Highways which serve long-distance trips, connect major population centers, have the highest usage and primarily provide a mobility function.
• Regional Tier - Minor US and NC designated highways which connect regional centers and typically serve high levels of demand for short distance like commuter travel.
• Subregional Tier - Minor NC routes and Secondary Roads which serve localized, short distance movements, have low demand, and provide land access to homes and businesses.
Highway System Definition(Tiered Approach)
Performance Based Management
• Uses data/statistical evidence to determine progress toward established goals/outcomes
• Measures efficiency, effectiveness of organization’s programs and operations (condition, quality, timeliness, reliability, etc.)
• Simple, understandable, logical, repeatable
• Shows a trend over time

Performance Based Management
Results, Benefits and Expectations• Uniformly constructed, maintained & operated Highway System
• Data drives decision making
• Shift to Outcome Based approach with clear goals– Move from a reactive to a planned approach– Increased focus on preventive maintenance– Target LOS by tier– Emphasis on planning & scheduling
• Highest & best use of resources
• Clearly defined performance expectations for operations
• Increased accountability and flexibility
• Challenging and rewarding workplace
