1. Summary of 2004 Summer Workshop in Toronto
Bruce Zvaniga, P.Eng.
Acting Director, Traffic Management Centre

2. Signal Coordination Issues
Obstacles to Good Coordination
Multi-modal competing/conflicting demands
Some techniques to address these demands
Resonant cycle lengths
Discussion on research needs

3. Reality Check

4. Why Coordination isn’t Easy

5. Denney’s Word of Wisdom

6. Competing Demands We No Longer Just Move Cars

7. Good Old Days-Simpler Times?

8. Who Wins?
Different Modes have different optimal signal timing parameters
Pedestrians want the shortest waiting time possible (short cycle lengths)
Protected left turn phases require longer cycle lengths
Transit vehicles move more slowly between signalized intersections than general traffic

9. Cycle Time Selection Methods

10. Resonant Cycle Lengths

11. Potential Benefits

12. Will ITS Solve This?

13. Research Needs Need for fundamental research on multi-modal control
Need clearly defined objectives – and need to communicate these in “easy to understand language” to the public and political decision-makers
Need to define operating resource requirements to support good signal timing
