Existing Efforts County developed a comprehensive annual signal coordination programProactive approach to correct potential operation problems before citizen complaints are receivedStudies considered adjacent signals ignoring jurisdiction ownershipSuccess of the system is realizedCoordination of systems is real – limited by congestion and existing intersection capacity

Program Cost
Initial Cost: $ 5,000– Purchase Synchro, SimTraffic & GPS unit
Annual Cost: $20,000– Collect volume and geometry data– Survey existing traffic control devices
Exploit Available Resources: $ 0 – 20 to 25 staff hours per intersection

Conclusions
County and City have established informal agreements to coordinate maintenance and operation of traffic signalsThere is a perception that traffic signals are not coordinatedThe real problem is congestion and not enough intersection capacityThe County is committed to improving mobility, safety, fuel efficiency, and air qualitySince 2000 the number of timing complaints in the County has significantly decreased
