Study on the simulation of traffic navigation predictive control

This paper puts the implementation procedure of dynamic traffic assignment under the framework of predictive control so as to satisfy the requirements of real-time traffic navigation. The algorithm of traffic navigation predictive control is proposed, which is implemented on the rolling horizon including such three important parts as real-time traffic assignment, traffic-flow simulative operation and evaluation, and evolving best routes. The simulation results show that traffic navigation predictive control is a favorable computer control methodology. The optimization procedure proactively considers the effects of current traffic assignment on the links in the future, which can effectively prevent the congestion, realize the optimization of real-time traffic assignment of road network considering feedback, and at the same time provide the optimized routes for the travelers.
