These nine Montreal bus lines will offer service every 2 to 12 minutes
The Société de transport de Montréal (STM) is outlining its new plan to help commuters easily identify which buses pass the most frequently on its network.
Tuesday, the STM announced that 31 bus lines will now be grouped in purple under the title "high-frequency lines."
"What our customers value most is frequent bus service, which is why we want to make these lines stand out from the rest of the network," said Éric Alan Caldwell, chair of the STM board of directors. "As with the Metro, customers using these high-frequency lines don't need to plan their trip down to the minute. They can just turn up at the corner and know that the next bus will be there in a few minutes."
The STM notes the buses will be marked in purple to allow people to quickly locate them, both on the street and online on the website and mobile apps.
Network maps are slated to be updated in spring 2024.

"With their high ridership and wide geographic coverage, these high-frequency lines are the backbone of our bus network, providing service where customers need it most," said Caldwell. "The new distinctive colour of these lines will make it easier for customers to find their way."
This comes almost a year after the public transit authority stated it could not guarantee a "10-minute max" due to financial strain paired with a small post-pandemic ridership.
The decision was overturned last spring after the STM received $26.5 million in funding from the Autorité régionale de transport métropolitain (ARTM), which oversees transit in the Greater Montreal area.

In addition, the public transit authority says it plans to add additional departures on approximately 75 other bus lines, with as many as 30 more on some lines, to address the increasing number of workers returning to the office.
The STM bus network is comprised of 200 lines covering all 500 square kilometres of the Island of Montreal.
Its 31 high-frequency lines account for over 50 per cent of ridership.
