【Abstract】 Two forms of fleet compression, “deceleration compression” and “parking compression”, were proposed. Based on the traffic wave theory, the relations between the number of stops of the coordinated fleet, the total delay of the coordinated direction and the compression time were derived respectively, and the ideal phase difference between the upstream and downstream intersections was obtained. Taking the nearest ideal phase difference of the actual phase difference as the optimization objective, a coordinated optimization model of road two-way signals was established. Guyang Road in Zhenjiang City was selected as the research object, and the model optimization scheme was simulated by VISSIM simulation platform. The results show that compared with MULTBAND model, the two-way average delay of this model is reduced by 16.7% and the number of stops is reduced by 21.7%.更多还原
