Mixed traffic micro-simulation of urban branch roads

At present, traffic micro-simulation studies are mostly based on the following model and lane changing model, which are the fundamental models. What make them distinct are their different forms and parameters. Although these methods can simulate the foreign traffic system fairly well, they can not precisely simulate the mixed traffic of Chinese urban branch roads. This study, which focuses on the unique situation of Chinese motorized vehicles and non-motorized vehicles advancing in a mixed way on the urban branch roads, puts forward a new model that can be applied to motorized and non-motorized vehicles. It is an advanced model for mixed traffic on urban branch roads. Take motorized vehicles for example; it will no longer be limited to fundamental forms, such as free driving, following driving or lane changing driving and so on, but will always be in an advanced state. There is no rigid lane dividing principle when the vehicle is advancing. Its lateral location, speed and other factors depend on the comprehensive traffic circumstance around it. In theory, there are numberless possibilities and choices. The principles of the non-motorized vehicles model resemble the motorized vehicles model. When the model was built, we used the crossing bridge of north Jianshe street in Shijiazhuang for testing and verification. It turned out that this method can make an accurate micro-simulation of mixed traffic on Chinese urban branch roads. In this way, it filled the blank left by the imported software.
