Left-turn Track Function of Bicycle Flow in Intersection

The study of bicycle flow left-turn track is the basis of studying the traffic conflict between left-turn bicycles and motor vehicles. This paper built the two-dimensional coordinate system of intersection using its geometrical features, acquired the coordinate data of the left-turn bicycle traveling track through the video coordinate method, and applied the coordinate data to the two-dimensional coordinate system. Finally, the track function expression of the left-turn bicycle flow was founded using the method of regression analysis. This function is a quadratic function, and relevant parameters are only related to the geometric parameters of intersections. The construction of the intersection left-turn bicycle flow track function is significant to the optimization of intersection traffic management.
