Separate dual-left turn lane is a new type of inlet channelization, which has been tentatively set in many cities. Through the actual measurement and analysis, it is found that the separate dual-left turn traffic flow has obvious interference at the exit position of the intersection, the traffic efficiency is significantly lower than the entrance position. According to the analysis of vehicle mutual interference based on separate dual-left turn traffic flow at exit position and quantization model of force and relative position, this paper gives the range of safety distance between the left-turning vehicles driven in inner and outer lanes. It analyzed the turning angles of vehicles driven in both inner and outer lanes by the exit position. Based on all the researches this paper brings out a guide line setting method for vehicle flow release in the case of separate dual-left turn lane setting is proposed. This research fulfills the blank of the existed traffic guide line setting specification GB5768.2, which makes a significant theoretical support for the signalized intersection traffic guide line setting work.
