Autorité régionale de transport métropolitain

The Autorité régionale de transport métropolitain (ARTM; Metropolitan Regional Transportation Authority) is an umbrella organization that manages and integrates road transport and public transport in Greater Montreal in Quebec, Canada. The organization was created by the Government of Quebec on June 1, 2017, replacing the former planning mandate of the Agence métropolitaine de transport (AMT). It has assumed other key initiatives including Opus card operation and multiple other projects supporting transit.

History
In 2017, the AMT was dissolved and replaced by two newly created organizations, the ARTM and the Réseau de transport métropolitain (RTM). Its planning mandate went to the ARTM while the operation of the various commuter rail lines across the Greater Montreal became the responsibility of the RTM. Also known as Exo, the latter also acquired oversight of the public transport agencies of Montreal, Laval, and Longueuil.

Organization
The ARTM consists of six appointed chair members from the Montreal Metropolitan Community council and six transit experts appointed by Transports Québec, the provincial transportation authority.

Park and ride
The ARTM also is responsible for all Park and ride lots in the Greater Montreal region. It runs 61 park-and-ride lots, many that are connected to either metropolitan bus terminuses, STM Metro stations, or Exo commuter rail stations.

In addition, the agency also organizes carpooling, offering unloading spaces near public transit services in several of its park-and-ride lots, which allow for transfers to the bus, Metro or commuter train.

Future projects
The ARTM is undertaking several major projects:
 * Metro extensions: Extending the Blue Line by five stations to Anjou. The extension is slated to open in 2030
 * Extending the Pie-IX BRT system to Notre-Dame Street. The extension is due to open in 2027.
 * Study a major transit solution for the Grand Sud-Ouest area in Montreal. The project could possibly consist of a new light rail line or an extension of the Green Line into LaSalle, Lachine and Dorval.
 * Study a major transit solution to replace the cancelled REM de l'Est project, named PSE. In January 2023, it was revealed that the ARTM was planning on proposing a 21-kilometre light rail line consisting of 22 stations, at a cost of $10.4 billion.
