Bus Identification Module For Visually Impaired

Talking signs, guide cane, echolocations 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). The blind people in the bus station is provided with a ZigBee unit which is recognized by the ZigBee in the bus and the indication is made in the bus that the blind people is present in the station. So the bus stops at the particular station. The desired bus that the blind want to take is notified to him as he presses a button on the user module. The blind presses the query button to search for nearby buses and if he hears the required bus number he presses the Ok button. The input is then analyzed by the microcontroller which signals the voice record and playback IC to announce the bus number received from the bus module. 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 speaker. The blind takes the right bus parked in front of him as the driver is also intimated about the presence of a visually impaired person at the stop. This project is also aimed at helping the elder people for independent navigation.
