To solve the problem that the current intersection control form is fixed and can not adapt to the dynamic and random traffic flow. A new type of intersection dynamic control, variable channelization and traffic signal coordination control based on video traffic flow detection, is proposed. Real-time traffic flow is detected through video, and different channelization and information control schemes are adopted according to different traffic flows. Finally, taking the most common two-way four-lane lane as an example, the variable channelization and traffic signal coordination control scheme based on video traffic flow detection is designed and completed, including the channelization scheme design, the coordination and cooperation design of the main pre-signal light, the peak shift threshold design, the variable channelization and information control coordination design under different flow states and the transition design between the peak channelization scheme. And through the VISSIM simulation, from the parking times, queue length, delay three aspects of the operation benefit assessment under different flow state, verify the feasibility of the scheme, reduce the overall delay of the intersection, improve the efficiency of the intersection. It provides a new idea for the improvement of urban intersection.
