Intelligent location identification and passenger-alert system in Indian Railways using GPS receiver

The aim of this work is to develop an intelligent real-time interactive information system which senses the location and calculates the distance of the train to the destination railway station which is taken as input from the passenger. The system also calculates the average speed of the train from the start of the journey and calculates the estimated time remaining to reach the destination based on the remaining distance and the average speed. The proposed system facilitates the passenger to precisely identify the railway schedules which are associated with unexpected delays. The estimated time of arrival can be predicted with high accuracy as time remaining to reach the destination is estimated based on average speed of the train. The system would alert the passenger when the train is within a pre-specified distance to a mentioned destination. An alarm is activated once the distance is within a certain pre-specified limit, thereby functioning as a passenger-alert system. The purpose of this alert system is to make sure that the passenger travelling in the train alights comfortably at the intended destination. A novel embedded system has been designed interfacing a GPS receiver with a host Field Programmable Gate Array (FPGA) board.
