Study On The Microcosmic Behavior Of Straightforward Bicycles Getting Across Right Turning Vehicles In The Same Direction

Mixed traffic flow, which is the main characteristic of large cities in China, is regarded as one of the primary reasons for serious traffic congestion. In the signalized intersection, great interference occurs between the bicycles and motorized vehicles which are in the same phase but heading for different directions. These interferences severely reduce the traffic capacity of the intersection, deteriorate the hidden trouble on traffic safety and make the traffic management very hard to be implemented. Model focused on microcosmic traffic behavior is one of the powerful tools for the study on mixed traffic, regardless the lack of mature and sophisticated model and the related theoretical system.Combined with one project under subsidy of National Natural Science Foundation conducted by my supervisor "Study on the mechanism and parameters calibration of interference between bicycles and vehicles in signalized intersection", this paper studies the microcosmic behavior of the interference between bicycles and vehicles in signalized intersection. Using the interference between straightforward bicycles and right-turn vehicles in the same direction as the case study, we build a mathematical model focused on the one-way interference of vehicles to the vehicles. The main steps we perform the study are summarized as follows: firstly, collect real traffic flow data of two classical intersections in Beijing by means of taking videos; then, analyze the collected data and try to obtain the useful data and principles existing among them; use the refined data and the related traffic flow theory to build the model for straightforward bicycles and bicycles platoons and through vehicles, respectively; Comparing the results with the real data, we find the model we build really reflects the real traffic flow in a very good manner, which justifies the validity of our model.
