5 measures implemented in Laval
Bus Preferential Measures (BPM) [definition]
Bus preferential measures (BPM) are devices and road setups that give priority to public transit vehicles and while simultaneously reducing roads congestion in Laval.
These preferential measures for buses are a whole in which every measure contributes on a scale that may seem minimal but, at the end a route, allows users to gain many minutes.

A smart system enabling communication between traffic lights and vehicles while shifting priority to buses. The STL system only emits an automatic priority request when a bus is running late and must catch up.
The STL system was custom designed and is unique in North America, and even in the world: It simultaneously processes the number of minutes to recover AND the number of passengers on board in order to assign priority.
All STL vehicles are equipped with a Transit Signal Priority System
- 309 buses
- 23 paratransit vehicles
- 232 intersections = 90% of the STL network = 75% Laval traffic lights
A road lane reserved for buses. Other vehicles, such as taxis, paratransit vehicles, and first responders, are often allowed to use reserved lines.
The use of reserved lanes does, at times, pose certain use restrictions.
- 14,4 km of new reserved lanes
- Nearly 1 km of which are central reserved lanes on Le Corbusier Boulevard

The ‘candlestick’ type traffic lights are part of the Transit Signal Priority System that ensures priority is given to public transit vehicles.
In Laval, these lights are part of a smart signal system that provides priority only when a bus is running late. They are also integrated in a complementary manner with the bypass lanes to the right.
What does it look like? An extra round black light with a vertical white bar in the middle is added to the overhead signal box.
What to do when the white bar lights up
Motorists have nothing to do when a ‘candlestick’ light lights up. They should simply wait for the green light just like at any other intersection.
- 11 new 'candlestick' lights
Bypass lanes are short stretches of lane added to the right near the intersections.
Bypass lanes have three main positive effects on traffic:
- Buses can bypass rush hour road traffic;
- They are then better positioned to take off in priority at the green light or at the 'candlestick' light.
- Motorists get the advantage of making an easier turn thanks to this lane.
- 6 new bypass lanes
Studies show that moving a stop past the intersection helps gain precious seconds.
This tactic makes perfect sense. Coupled with our Transit Priority Signal System it allows buses to cross the intersection instead of stopping at the light.
It is therefore more efficient to have the stop placed PAST THE intersection.
These small tweaks have a big impact on the travel time of our buses.
- 77 stops or shelters moved
