The mobile app uses context-aware self-adaptive computing to deliver live, customised data to passengers en route.

The inclusive application, complete with useful information for all passengers, was created through a partnership between Ryerson University's Digital Media Zone (DMZ) and Sweden's Appear Networks.

Régie Autonome des Transports Parisiens (RATP) commuters can now download the free software and set up their user profile. Information is then automatically sent to their mobile phones according to their profile and contextual information.

For instance, users can receive notifications such as the location of station elevators and Metro transfer points; facilities and nearby businesses; updated schedules for connecting trains; and availability of services at each station.

For blind and low-vision passengers, the Mobile Transit Companion uses a speech-enabled, gesture-driven user interface. For other user groups, including the elderly, deaf or hard of hearing, or passengers with reduced mobility, the application offers an intuitive and easy-to-use visual interface.

Project leader Hossein Rahnama, a Ryerson postdoctoral student and DMZ Steering Committee member, commented: "We are specialising in context-aware consumer applications in airports, airlines, trains, subways, buses, etc. With RATP, our focus was on passengers with special needs because those communities could really benefit from such applications, even though they are often not considered when developing apps."

The Mobile Transit Companion's positioning function is integrated with a web-based monitoring service so that public transit staff can easily locate and assist passengers with special needs.

The only existing social tracking application for public transit passengers, this monitoring service has the capability to be shared with friends and family. Using the interface, the transit authority can message selected passengers, which is particularly helpful for deaf or hard of hearing passengers who can't hear announcements made over the PA. Messages are communicated to each passenger according to the information on his profile, e.g. the message will be interpreted from text to speech if he has indicated Low Vision.
