Train Control System for Efficient Track Usage and Reduce Road Traffic

Automatic Train Control (ATC) is the term for a general class of train protection systems for railways that involves some sort of speed control mechanism in response to external inputs. ATC systems continuously monitor all movements of the trains on lines and at stations and provide safe signaling. A large number of automatic functions support the high speeds possible and enabling the line and network resources to be utilized to maximum capacity. ATC use to schedule multiple trains between two stations with small meter gap between adjutant trains. So the railway department can run more train by using the same track without accident problem. Population explosion has resulted in a series of problems, such as traffic jam, environment pollution, and energy crisis. This project focus on channel estimation errors and the tradeoff between MIMO multiplexing gain and diversity gain in making handoff decisions. The handoff problem is formulated as a partially observable Markov decision process (POMDP), and the optimal handoff policy can be derived to minimize the handoff latency.
