Toronto Traffic Light Improvement Project

1. We often see traffic lights remain RED for lengthy periods even though there are no people or vehicles crossing the road, treating the main road like a side road.  Although the minor road has no more vehicles, the lights don't change.  It seems that traffic volume sensors are not installed in these places.  Major upgrade of ancient traffic lights is required.

2. During the rush hour, major roads with more traffic should be given higher priority, reducing the chance of seeing a RED light.  EX. Lawrence Ave. East.  Vehicles are frequently stopped at every major and minor intersection.  Traffic lights on this road are too frequent and always out of sync. 

3. Traffic light synchronization is required for traffic lights in close proximity. 

4. Minor road crossing should be disabled during rush hour.  Whenever possible, maintain a RED light and create a sign for motorists to turn right during rush hour.

5. Extended GREEN light for construction affected streets.

6. Cyclic increased priority for reduced priority direction. EX.  Northbound at Keele & Rogers, Northbound at Black Creek & Lawrence.

7. Street cars and buses need crossing priority.  We already use transponders for automatic station calls.  We can also use transponders to communicate with the traffic light so public transit vehicles receive crossing priority.

8. Traffic light differential between vehicles and pedestrians.  Whenever possible, vehicles should be allowed to turn right at the start of the GREEN light.  The pedestrian GREEN light should be delayed.

9. Yonge & Bloor, Bay & Bloor universal pedestrian crossing lights should be redesigned.  Pedestrians are already given the time to cross in all directions during the "All Vehicles Stop" round.  In the next 2 rounds, all pedestrian lights should be RED, allowing vehicles to turn.
