Abstract
A train rescheduling system using Timed Coloured Petri Nets is proposed. Traffic in a single track area named, “Chumphorn” is modelled and analysed. This area is selected because of its high traffic density. Even with a small traffic disruption in this area, the consecutive delays can be severely propagated. Although Timed Coloured Petri Net (TCPN) formalism is a natural choice to model a train scheduling problem, we rarely see TCPN used in real world practice. We envisage that there are two problems. First, interacting with the TCPN model requires programming skills. Second, analysis of the traffic in a large railway network often encounters state explosion. This paper suggests the solutions to these problems.
