Mobile Agent based Train Control System for Mitigating Meet Conflict at Turnout

Timeliness and correctness in conflict detection and resolution mechanisms form an important component in railway operation especially when the decision process involves human factors. The current approaches used by Indian railways (IR) for conflict management can be enhanced through the use of Mobile Agent (MA) technology. The use of MA technology appropriates due to their asynchronous, autonomous, robust, and fault tolerant properties. In this paper, we discuss certain train operation conflicts and detail about meet conflict followed by implementation of MA based meet conflict management system for IR. Due to the suitability of formal modeling techniques for implementing highly dynamic and concurrent systems, in our rail traffic scenario we modeled the meet conflict detection and resolution mechanism using coloured petri net (CPN).
