1 10 Years of Evolution and Lessons Learned

2 PIERCE TRANSIT Bullet Heart of the Puget Sound Service area: 292 square miles Annual ridership: 15.4 million 263 buses providing local and regional services to a Pierce County area population of just over 821,000

3 DEMONSTARTION PROJECT 9-weeks on an 11- intersection corridor. 15 buses - 2 routes Demonstration corridor 2 control strategies; green extension quick green return Budget - $75,000.

4 2001 IMPLENTATION PHASE 1 $2.69M 7 corridors 110 project intersections Opticom emitters installed on entire fleet Opticom equipment for Tacoma Fire Control strategies for system operation Completed 2004

5 2010 IMPLENTATION PHASE 2 Area 1 Downtown Tacoma 60 intersections mph speed limit Area 2 44 intersections 17 miles mph speed limit

6 BENEFITS Reduction in transit delay Improved transit speed and reliability Reduction of travel time Reduced fuel consumption Improved system speed

15 PARTNERSHIPS Address Jurisdictional Concerns

16 MEETING GOALS Meet Agency and Jurisdictional Goals Agency Project Objectives: Improve Transit Service Reliability Maintain Transit Travel Times along the corridors Reduce delay at project intersection Jurisdiction Project Goals: Deploy compatible equipment at project intersections that provide the greatest public benefit. Verify operational benefits in accordance with agency traffic engineering requirements. Provide measurable and quantifiable project results and outcomes. Develop strong jurisdictional partnerships for project coordination and implementation.

17 IMPLEMENTATION GUIDELINES Satisfy Jurisdictional Implementation Guidelines Maintain minimum pedestrian crossing time during Maintain minimum green time for the left turn movements Maintain signal coordination during Avoid skipping any vehicle phases Do not service consecutive calls for selected bus route only

18 MAINTENANCE Maintenance is important to the long term success of the program. Partnerships with local agencies may be required. Opticom emitters will degrade over time. This will change the detection point for each intersection. Dirt and vibration on the bus can reduce the effectiveness of the emitters. Detectors can vibrate and rotate changing the detection distance. Newer technologies can improve the service life and reduce maintenance costs (LED emitters, GPS based systems).

19 OPERATIONAL CONSIDERATIONS Upgrades and maintenance can enhance the benefits and operations of the system. Data analytics provides a vital feedback for maintenance operations and planning. Proper detection is vital to operations of the system. systems can piggyback onto technologies and communications that are currently available in the corridor. Partnerships require good delineation of roles and responsibilities.
