Transit Information Access for Persons with Visual or Cognitive Impairments

We are developing a location-based information delivery system to facilitate efficient and safe use of public transportation by people who have visual or cognitive impairments. This system comprises Wi-Fi beacons (access points) that are placed at bus stations and inside bus vehicles. Users of this system receive information on their cell phone, without the need for GPS or for Internet connectivity. The system allows one to receive information about an upcoming bus at a bus stop and to select a specific bus line. Once the desired bus arrives, the system automatically connects to the access point on the bus vehicle and remains connected while the user is riding the bus. The user can specify a desired bus stop, and the system informs the user (by a speech message) with enough advance notice when the bus is approaching the stop.
