PASSENGER BUS ALERT SYSTEM FOR EASY NAVIGATION OF BLIND

ABSTRACT Guide cane, echo locations are all useful in navigating the visually challenged people to reach their destination, but the main objective is not reached that it fails to join them with traffic. In this project we propose a bus system using wireless sensor networks (WSNs)-(ZigBee).The blind people in the bus station is provided with a ZigBee unit which is recognized by the ZigBee in the bus. The blind gives the input about the place he has to reach using microphones and the voice recognition system this input is then analyzed by the ARM-7 which generates the bus numbers corresponding to the location provided by the blind. These bus numbers are converted into audio output using the voice synthesizer APR9600.Whenever bus has entered into bus stop buzzer will be ON to indicate the blind person. The desired bus that the blind want to take is notified to him with the help of speech recognition system. The ZigBee transceiver in the bus sends the bus number to the transceiver with the blind and the bus number is announced to the blind through the headphones. This project is also aimed at helping the elder people for independent navigation
