Safety alert signalling measure in train transportation system and its automated behaviours using GPS

Abstract

The advancement of wireless communication and GPS systems paved the way for better monitoring in Railway Transportation systems. The GPS based monitoring of trains will help to track trains, better scheduling and avoids any mishaps. In the existing system, the scheduling of trains, traffic railway signalling is manual and less accurate in predicting train arrival destination time and no/or very less emergency alert broadcast sent to from and to station in case of any mishaps. Automated Train scheduling will be incorporated with the help of GPS system and if there are concurrent trains running in the same path, scheduling is automated to avoid deadlock scenario and train waiting issues and hence train travelling time can be reduced. Traffic Signalling is better handled with additional proactive measures by sending broadcast message to the nearest from or to stations with current latitude location details of train. The nearest station where train has been halted can be found by using the shortest distance using proposed Hybrid shortest distance algorithm using latitude conversion to weight and applying dijkstra to find the shortest distance. Accurate Train schedule timings are tabulated and expected train arrival at the destination will be precise enough as tabulations are dynamic. Hence necessary steps can be carried out for false traffic and immediate medical services can be provided for mishaps and reduces the number of accidents.
