The aim of study is to explore the expansion of traffic flow and the conflict between motor vehicles and non-motor vehicles in the left turn traffic mode. Through the investigating data, this paper studies the influencing factors of the expansion width of left turn non-motor vehicle flow from three aspects of non-motor vehicles, motor vehicles and intersections, and then establishes the expansion width model. At the same time, according to the conflict and left-turn trajectory, the conflict model between motor vehicles and non-motor vehicles is established.The results show that the selected index factors have a significant effect on the expansion width, and the established model has a general effect through analysis. Finally, the spatial planning method of intersections is proposed through the model, which provides a theoretical basis for reducing the influence of non-conflict interference and optimizing the design of intersections.
