基于車聯(lián)網(wǎng)的交通管控機制設計與驗證
[Abstract]:In recent years, the automobile industry has developed rapidly and the car ownership is increasing. At the same time, the road traffic congestion has also been affected by more and more people. In order to alleviate traffic congestion and improve the vehicle travel efficiency, a set of traffic control and control mechanism based on the vehicle network is proposed. First, the fixed long rotation method and the traffic flow are combined. A semi real time traffic light control method is proposed for two existing main traffic light control methods of the quantity response control method. In this method, the traffic light controller obtains the optimal traffic light phase strategy of this intersection according to the predicted traffic flow information, and minimizes the waiting time of all vehicles in this intersection. Secondly, in order to improve the individual user. A heuristic dynamic path planning algorithm is proposed. Based on the Dijkstra algorithm, the algorithm uses a heuristic method to calculate the weight of the road section, so as to plan the optimal path, so that the vehicle can avoid the congestion section as much as possible. In order to verify the performance of the proposed traffic control mechanism, the traffic flow simulator SUMO and the traffic flow simulator are used to verify the performance of the traffic control mechanism. The simulation experiment of the network simulator NS3 shows that the proposed traffic control mechanism based on the vehicle network can effectively reduce the waiting time of the vehicle, alleviate the traffic congestion, and improve the traffic condition of the whole road network.
