Abstract:

An approach was proposed for the modeling of a signalized traffic intersection using Timed Hybrid
Petri Nets (THPNs) to alleviate traffic congestions and improve driving safety. The proposed model could
comprehensively capture and simulate vehicle mobility when crossing a four-way signalized intersection at
a specific phase plan. Continuous nodes (places and transitions) were used to represent vehicles flow and
queues at intersection while discrete nodes were used to represent discrete events such as phase change and
enabling/disabling vehicle movements. Using timed transition, time delays between different time instances
of the intersection were also considered to make the model suitable for real-world analysis and simulation.
Simulation results of the proposed model were added and analyzed. The method can be useful for studying
traffic flow patterns at intersections and has the potential to improve traffic environment.

Key words: traffic congestion, driving safety, traffic intersection, vehicle mobility, timed hybrid Petri nets
