| Abstract: | A model of the urban traffic signal control system is established by using the extended Petri nets with time and constraint arc.The intersection flows are composed of six discrete phases and each phase has its own time label.It guarantees the vehicle and pedestrian in different direction safe.An method is given to verify the model soundness. |

| Keywords: | time extension intersection arc Petri nets phase |
