An intelligent wireless bus-station system dedicated to disabled, wheelchair and blind passengers

The urban public transportation systems are usually not appropriate for disabled, wheelchair and blind passengers (DWB). This paper introduces the MobiPlus system that aims at improving the public transportation service so as to meet the needs of DWB. The MobiPlus system is an intelligent wireless bus-station interactive system with the integration of multi-wireless techniques (RFID, ZIGBEE, WiFi, and GPS). It consists of three subsystems: DWB detection subsystem, wireless communication subsystem, and bus service subsystem. This paper presents the design of the MobiPlus wireless interactive system at different levels, such as hardware, software and protocol, and also gives the function description of its three subsystems. Currently, this system has been implemented and is under evaluation at Clermont-Ferrand city, France.
