Bus preferential measures (BPM)

New reserved lanes on Viau

Why bus preferential measures?

Bus preferential measures (BPM) consist of installations on the road system that ensure priority is given to public transit, thereby improving the reliability and on-time delivery of service, and increasing public transportation’s attractiveness and modal share.

Such measures make it possible to provide faster, more regular and timely service, while giving public transit a competitive edge over cars. They result in shorter travel times for passengers, a lesser environmental impact thanks to fewer GHG emissions, and lower deployment costs.

BPMs include:


27 reserved lanes exclusively for buses and taxis (at December 31, 2013)

They allow buses and taxis to operate on an exclusive roadway, thus avoiding traffic congestion, while offering significant advantages in terms of reliability, timeliness and comfort for passengers. 

They feature ground markings, separate signage (either lane-side or overhead) and are operational during rush hour, off-peak periods or 24 hours a day.

Queue bypass lanes

With road markings and special signage, queue bypass lanes enable buses to avoid traffic as they approach certain intersections.

« Candlestick » priority traffic signals

When the vertical white light appears on traffic signals, buses are given priority and a head start over motorists.

-    Priority departure for buses at intersections

  • 4- to 5-second head start
  • In the direction of heaviest ridership

Active priority traffic lights

Buses request priority from traffic signals as they approach an intersection. Either the green light or white priority signal is extended, allowing the bus to drive through and avoid stopping for a red light.

PILOT PROJECT - bus-bike-taxi reserved lane between Rosemont and Pierre-De Coubertin

Montréal is well known for its citizens’ interest in alternative methods of transportation including buses and bikes. This pilot project allowing for the cohabitation of these two forms of transportation.

Viau reserved lane offers several benefits:

  • Trips that are more efficient
  • Service that is more regular and more punctual
  • Lower greenhouse gas emissions in your sector
  • A safe and comfortable layout for the movement of buses and bikes

It’s a first!

This is the first test of cohabitation between buses and bikes in a reserved lane. We will conduct assessments and,depending on the results, this type of reserved lane could be implemented elsewhere in Montréal.

Ride aboard the 105 Sherbrooke and 420 Express Notre-Dame-de-Grâce bus lines and travel along a new reserved lane for buses and taxis, Monday to Friday.

Advantages of the reserved lane

  • More efficiency way to travel
  • More regular and on-time delivery of service
  • Fewer greenhouse gases on these lines

Hours of service

  • Eastbound : between Elmhurst and Girouard, from 6:30 to 9:30 a.m.
  • Westbound : between Addington and West Broadway, from 3:30 to 6:30 p.m.

On-steet parking is permitted on opposite side of reserved lane during operation hours.

This reserved lane for buses and taxis is a joint initiative by the city of Montréal and Transports Québec.
