To meet the expectations of today’s passengers, Société de transport de Montréal (STM), the provider of public transport services for Montreal, decided for the implementation of an ITS project called iBUS. The project aims to deliver updated passenger information at all times. Adjustments to the schedule, caused for example by service disruptions, become public in real time to allow riders to make the best decision while en route. Of course, reliable information is also available before the trip. Further important goals of STM were to improve punctuality and regularity of the bus service, as well as provide greater safety aboard buses.
