Traffic Signal Maintenance
10
State Forces

• - Inside Cabinet Preventive Maintenance (PMs)
• Contract Monitoring of Signal Maint. Contract
• Emergency Response
• Primary function
• On-call at night/weekends
• Mobile based response
• Reduced response times

11
Maintenance Contract

• - Outside Cabinet Preventive Maintenance
• - Mast arm, signal heads, cameras, loops
• - Planned Corrective Work
• Small corrective items (cameras, wiring, heads,
  pre-emption, conduit, junction boxes,
  cabinet/flasher foundations)
• Unit pricing and Task Order based
• - Performance Based contract

Why are we doing this?

• Improve emergency response to signal problems
• Response time impacts traffic flow and motorist
  safety
• Reduce time law enforcement needed for traffic
  control
• Improve condition of signals
• Reduce number of signal problems, improve
  reliability
• Extend asset life
• Begin planning for life cycle replacement
• Maintain core competency
• Troubleshooting and emergency response
• Inside cabinet equipment

14
Partnerships with Cities

• City of Winchester
• Used signal consultant (SWA/WRA) for timing
  improvements on border corridors
• Route 7 5 minute reduction, 75 less stops
• Route 50 East 40 sec reduction, 28 less stops
• Route 50 West 1 min reduction, 70 less stops
• Route 11 South 45 sec reduction, 50 less stops
• Multi-year plan to replace signals/controllers
• City of Charlottesville
• Coordination on Rte 250 signal improvements
• Future Vision

Integration Arterial/Freeway Systems

• GOAL
• Develop a signal control system within Region
• Integrate Arterial Management into Freeway Mgt
  System
• RESULT Improved reliability, improve traffic
  flow, fewer intersection crashes
• Phased Approach
• Re-design TMC Network to house existing signal
  software (Marc NX)
• Upgrade remote communications to/between signals
• Traffic Signal software acquisition
• Integrate Arterial/Freeway Mgt Systems
