1. TSP Must Fit Within An Overall Agency ITS Plan

2. Transit Priority Data Needs Vehicle Location –Speed Door & Lift Status –Predictions Passenger Counting Stop Location –Near side –Far side Vehicle Routing –Stopping –Turning Schedule Adherence Vehicle Identification CEE582

3. Let’s Just Look at AVL Systems Do we want one AVL system that meets all needs, or multiple AVL systems?

4. AVL Systems GPS Sign Post (beacon) Dead Reckoning Sign Post + Dead reckoning GPS + Dead reckoning

5. AVL Systems Does the bus know where the bus is, does the traffic management center know where the bus is, or does some device in the field know where the bus is? Information provided Communication required Flexibility / content of that message

6. AVL Systems How do you intend to use that information? –Fleet management? –Labor management? –Labor oversight? –Automated control? –Security?

7. AVL Implementation Issues Political Technical Institutional Financial Legal CEE582

8. AVL Implementation Issues Political – Big Brother –Who gets to know where the bus is? –Who controls that data? –How will that data be used? Homeland security? CEE582

9. AVL Implementation Issues Technical –Move to proactive fleet management –Which technology is best? Purchase price Maintenance / operations price Long term value, including flexibility –Not really “plug and play” yet –Reliability of communication network

10. TSP-Related Systems CEE582

11. Transit Management Center Location Monitoring Schedule Information Desired Headway Ridership Monitoring Service type CEE582

12. Traffic Management Center Signal System Management Signal Coordination Signal Timing Priority Restrictions Feedback CEE582

13. Traffic Signal Services request for priority Resolve conflicting priority requests Recovery from priority request CEE582

14. Scenario 1 CEE582

15. Scenario 2 CEE582

16. Scenario 3 CEE582

17. Scenario 4 CEE582

18. Logical System Model CEE582

21. TSP Implementation Issues Confusing array of technical choices: detection, communications, control strategies, integration with other systems Complex organizational issues in multi-agency and multi-jurisdictional setting Need better guidance to navigate choices and issues CEE582

22. More TSP Implementation Issues Lack of standardized reporting on impacts and benefits to allow comparisons Practical information hard to obtain by practitioners All simulation and optimization tools, and traffic controllers are not well suited for TSP CEE582
