Promoting inclusion for Montrealers with functional limitations

The paratransit division of STM in Montréal, Transport Adapté, contributes to social, professional and economic inclusion of 30,000 registered users whose functional limitations have a significant and persistent impact on their mobility.


How did HASTUS help?

STM used the HASTUS-OnDemand tools to optimize service provided with its own fleet of 86 minibuses and by 275 accessible taxis and 1,000 standard taxis operated by 13 companies, matching customers’ functional abilities automatically to the type of vehicle for the most cost-effective trips.
