Abstract

Timed Petri nets (TPNs) are useful for performance evaluation discrete event systems due to their mathematical formalism. This paper proposes to use TPNs to model parallel railroad level crossing traffic safety control systems. Double-track railroad lines by using TPNs are illustrated. The resulting models allow one to identify and thus avoid critical scenarios in such systems by conditions and events of the model that control the phase of traffic light alternations. Their analysis is performed to demonstrate how the models enforce the phase of traffic transitions by a reachability graph with timed information method. The liveness and reversibility of the proposed model are verified. This helps advance the state-of-the-art in traffic safety related to the intersection of railroads and roadways.
