Abstract: | Incidents and waiting for train connections are registered by dispatchers as sources of train delays, but route and headway
conflicts are not always clearly recognized. Moreover, traffic management and route setting are the primary task of dispatchers
and signallers, whilst monitoring and incident registration is not allowed to take up too much of their time. This paper describes
a tool that automatically and without discrimination identifies route conflicts and the train numbers involved. It is based
on standard train describer and infrastructure messages recorded on the Dutch railway network. The logic of these messages
is captured in a coloured Petri net (CPN) model on which a prototype tool for route conflict identification and estimation
of knock-on delay has been developed. |
