FINDINGS



After implementing traffic signal priority for a light-rail transit (LRT) line along an urban arterial in Toronto, system operators were able to remove one vehicle from service and maintain the same level of service to passengers along the corridor. This reduction in equipment reduced operating costs. However, the transit agency had some concern with system operations at intersections with near-side LRT stops. The system caused increased delay to the transit vehicle by extending the green time while the vehicle dwells at the stop, typically reaching the maximum phase length permitted before the vehicle finishes allowing passengers to board. This increases the time that the vehicle must wait at the stop for the following green phase. The system operators have also received complaints regarding increases in pedestrian delay due to the signal priority system.
