Study On The Model And Impact Of Lane-changing Vehicles For City Road

Model of traffic flow is one of the basic researches in urban areas of traffic. By the analysis of the variety of traffic, to describe the general characteristics of the actual traffic of the traffic flow model, and reveal the basic rules of traffic flow, so as to provide reference and a basis. For the transport infrastructure planning and design.The Vehicles lane-changing behavior is the most common traffic phenomenon .the Behavior for Road described the various kinds of the traveling lane-changing behavior. The Behavior for Road has a great impact for the traffic flow, especially the traffic section, however the research for the Behavior for Road is lagging behind. The reason, in addition to Road the complexity of the act itself, there are significant limitations for the establishment of the premise of the model.In recent years, the cellular automata theory can well describe the traffic flow of these non-linear phenomena, and a lot of cellular automata-based traffic model Appeared. The paper discusses the ideas and methods to build the traffic model based on cellular automata theory. Taking into account the change of lane-changing decision-making is a thinking process, fuzzy control variables used language similar to the method of reasoning, it is appropriate to describe such a major decision by the people to do the process of subjective judgments. Therefore, based on the cellular automata, the fuzzy logic-based model for the simulation of a better vehicle for acts Road.First, for the vehicle characteristics Road acts carried out a depth analysis, summarized the existing model and compare their advantages and disadvantages. Then, established the principle of channel model for urban road based on the theory of the cellular automata. Considering the various circumstances and the impact of the driver's own factors, putting forward the concept of pressure change, according to the compulsory and free for Road sex-for-Road Road, respectively, given the conceptual model.As a result of the impact of the road, traffic and the features of the driver, the impact of some differences in behavior of the Road. On the basis of the detailed discussion for the model, the paper provides A series of proposals to avoid a negative impact on urban transport.
