摘要
Aimed at actuated intersection control problem,a real-time queue length estimation method is proposed under a connected vehicles technology environment.Base on this method,a model of actuated intersection control based on dynamic combination of traffic flow is put forward.The above-mentioned control logic was achieved completely with the VISSIM-COM programming.Choosing a typical intersection as simulation experiment object,comparisons with the fixed time plans and the traditional actuated control in the same condition was made respectively.The results of simulation indicate that the model effectively decreases average queue length and average delay time as well as improves operating efficiency of intersection significantly.In addition,it makes up the defects of the actuated control technology in the nearly saturated or supersaturated traffic conditions.
