Traffic Signals


Traffic signals are designed, installed, operated and maintained by the City of Ottawa ensuring the safe, efficient and sustainable movement of people and goods within the community through the use of:

  • Technologically advanced software and hardware
  • Signal timing, including special phasing for peak hours, weather conditions, special events and construction
  • Progression and synchronization between signals
  • A cohesive system which maximizes the capacity of existing infrastructure

The operation of traffic signals has a major impact on stops, delays and travel times for various users of the transportation system. The application of state-of-the-art technology and in-house software development has resulted in a customized, central, traffic-control system and traffic-control equipment tailored specifically to the City’s needs. This improves safety, efficiency and reliability at more than 1040 signalized intersections located within the City of Ottawa.

Mitigating the effects of congestion and the increasing demands on the transportation system helps to reduce fuel consumption and the negative impacts to air quality. The traffic control system is continuously monitored, with real-time adjustments implemented in response to peak hour congestion, weather conditions, special events and construction. Signal timings are continuously monitored and updated to reflect changing traffic patterns and volumes.

Information related to traffic signal operation, coordination, pedestrian signals, vehicle detection, left turn signals, and ordering traffic signal timing plans are listed.
