The PIS is aimed to integrate all local buses plying in the major cities with passenger information system as per guidelines of Ministry of Urban Development, Govt. of India. The system integrates all local buses plying in the city with central control station, Bus stand and Bus terminals. 

  The proposed Passenger Information System integrates & sends information across the network to the Bus Stop & the passengers about various items such as Estimated Time of Arrival, Departure, Route numbers, etc. It works seamlessly as follows:

While the bus is going on a route, the tracking device sends the location information to the controller at regular information. Based on the route selected, whenever the bus is close to the bus stop location, the controller alerts the driver of the next bus stop. It also announces the next bus stop on internal speakers. The System also controls the LCD at the Bus Stand / Bus Stop that displays the Estimated Time of Arrival of the next bus. This information is send to the LCD from the Bus via GPRS.
The above system operates automatically or can be manually driven as defined above.
