The analysis of vehicle behavior in the weaving section on the highway using a micro-simulator

Heavy congestion sometimes occurs in the “weaving section” of the highway road network and this phenomenon is noted from the point of view of the solution of traffic congestion. In this paper, the authors analyze the behavior of each vehicle in the weaving section by using a microscopic computer simulation model. The highway interchange used in the model is a weaving section in which two roads cross in an “X” manner and a number of vehicles traverse the interchange by changing lane. The model is described by three basic equations and these equations consist of simple forward movement, following movement and the stopping movement. In this study, the authors mainly analyze where behaviors of changing lane and braking occur in this weaving section, these analyses making it possible to investigate the smoothness of traffic flow
