This paper conducts a field survey of relevant intersections and analyzes their data. Through the analysis of the principle of turning left through the lane, set the lane in the appropriate position; On this basis, with the goal of reducing delays at intersections and improving traffic efficiency, the timing method of traffic signal control is applied to optimize signal timing at intersections under the conditions of cycle limits and lane length limits, and a reasonable pre-signal timing scheme is set up. VISSIM simulation shows that setting a left-turn lane at an appropriate location at an intersection and making a reasonable signal timing optimization can effectively reduce the delay of left-turn vehicles at the intersection and reduce the travel time and queue length. The results of this paper show that it provides certain theoretical support an...
