Yes, most traffic signals in the City are coordinated in order to minimize stops and delays. Ideal or "perfect" signal coordination is often difficult to attain due to varying speeds, congestion, the distance between signals and varying amounts of green time at each intersection. "Perfect" coordination for one direction of travel results in frequent stops and delays for the other direction.
When traffic volumes are relatively balanced, the traffic signals are timed so that the "reds" and "greens" are balanced in both directions. When the traffic flow is heavier in one direction, the signals are co-ordinated to favour the highest volume of vehicles. For example, a vehicle on 97th Street, travelling towards downtown during the morning rush period should arrive at more green lights than vehicles leaving the downtown via 97th Street during the same time period.
Signals along the South LRT (Light Rail Train) corridor are not coordinated. North and south coordination is provided by LRT pre-emptions of the signal.
