GTT’s Opticom TSP helps to improve performance for Laval buses

Global Traffic Technologies (GTT) has implemented its Opticom transit signal priority solution (TSP) in the city of Laval in Quebec, Canada in an effort to improve bus network performance and boost ridership. The TSP system is installed at 90 per cent of intersections in the city and on more than 300 buses and paratransit vehicles.

542 Global Traffic Technologies (GTT) has implemented its Opticom transit signal priority solution (TSP) in the city of Laval in Quebec, Canada in an effort to improve bus network performance and boost ridership. The TSP system is installed at 90 per cent of intersections in the city and on more than 300 buses and paratransit vehicles.


The Opticom TSP system implemented by the Société de transport de Laval (STL) provides buses with a green light to keep them on time, while data derived from the GPS-enabled system helps managers update and refine routes and schedules for a better passenger experience and, potentially, an increase in passengers using the system.

Using both conditional and relative priority has been key to managing the priority of their buses. With so many vehicles in the system, there was a need to implement a means of deciding which buses receive priority and when. The solution was to send priority levels derived from the buses’ on-board computers to the Opticom system. Different priority levels are determined by passenger counts and schedule data.

    The governments of Canada and Quebec will invest a combined $42.6m (£24.3m) for 26 projects by the Société de transport de Laval (STL) under the Public Transit Infrastructure Fund. The plan is part of a strategy to reduce air pollution and create inclusive communities where everyone has access to public services. One scheme involves the replacement of buses to expand and maintain the average age of the fleet, and studies to continue STL’s electrification program. It aims to improve the performance and

Opticom works alongside intersection controllers to help ensure emergency vehicles can move through intersections rapidly and safely, and public transit vehicles can avoid delays and adhere to schedules. When an emergency vehicle needs to navigate an intersection, the Opticom system on-board the vehicle sends a request to the intersect
