A novel hybrid petri net model for urban intersection and its application in signal control strategy

A signal control strategy based on model reference adaptive control is investigated with a new hybrid petri net model for urban intersection in artery. The hybrid petri net intersection model is simplified via the token transition. The new model can be more in touch with facts through the waiting zones and addition phases. The hybrid petri net is innovatively used as the reference model in the model reference adaptive control method. The predicted traffic flow is precisely computed by the support vector machine. Finally, a series of simulation results with the practical data verify the feasibility of the novel arterial petri net model and the effectiveness of the control strategy.
