Summary: | The invention discloses a closed-loop road network phase difference optimization method based on an improved cut-off method, and belongs to the technical field of traffic signal control. The method is characterized by comprising the following steps: S1, establishing a closed-loop road network connection priority level discrimination model based on fuzzy comprehensive evaluation, and determining a key intersection; s2, establishing a closed-loop road network phase difference optimization model based on an improved cut-off method; s3, determining a phase difference fine adjustment amount; and S4, obtaining a closed-loop road network phase difference control scheme. When the optimal phase difference of the intersection of the closed-loop road network is determined, firstly, on the basis of actual traffic parameters of the intersection and the closed-loop connecting line, the connecting line road grade, the green wave band width, the saturation degree and the traffic volume are selected as evaluation factors, and |
