A Study Of Bidirectional Green Wave Control Based On Random Optimal Graphical Method

With the increasing number of urban vehicles, traffic congestion is becoming more and more serious. Bidirectional green-wave coordinated control is one of the main ways to alleviate the city traffic congestion and improve the efficiency of city traffic. In this paper, a bidirectional green-wave control method based on random optimal graphic method is proposed. According to the different capacity of the road in both directions, the formula of bandwidth proration coefficient is established, and the green-wave bandwidth is allocated reasonably. The target formula of bidirectional green-wave and the target formula of the bidirectional additional bandwidth of the key intersection are used to find the suitable bidirectional green-wave band. The effectiveness of the method is evaluated using on an arterial road simulated by the VISSIM simulation software, and compared with the traditional graphic method. The simulation results show that the capacity of the optimized arterial road is improved effectively compared with the traditional graphic method.
