摘要

A HPN (hybrid Petri nets) traffic model, composed of discrete Petri nets and TdPN (timed Petri nets), is proposed for modeling dynamic traffic flows at non-signalized T-intersections in urban traffic networks. This model is used to solve two primary problems. One is how to formulate dynamic traffic flows at intersections. Another is how to simulate their behavior accurately and continuously. The discrete Petri nets represent the Levels of traffic priority, and the TdPN computes the corresponding time-varying quantities. The simulation results indicate that the model can represent the characteristics of dynamic traffic flows at non-signalized T-intersections and meet the requirements for modeling the urban transportation networks.
