Identification Method and Behavior Characteristics of Competitive/Cooperative Lane Changing in Expressway Weaving Area
摘要
Abstract
In order to improve the accuracy of lane changing model, a quantitative method of identifying competitive/cooperative (C/C) lane changing behaviors was proposed according to acceptance gap, headway time and time-to-collision (TTC). Firstly, the process of this method was described systematically;Secondly, the application of the method was verified by experiment based on vehicle trajectory data at expressway weaving area; Finally, explicit characteristics of C/C behaviors, such as the relationship between acceptance gap and relative velocity, trans-line ride (TLR) time, maximum velocity variation and jerk of lag vehicle were analyzed, and C/C lane changing probabilities under different acceptance gaps were also obtained. The research results show that the proposed method can effectively identify C/C lane changing behaviors in complex environment. Acceptance gaps of C/C lane changing behaviors follow normal distribution. The probability of competitive lane changing increases with the increase of gap when it is less than8 meters. When the gap is over 8 meters, it decreases with the increase of gap. When the gap is more than20 meters, the probability of cooperative lane changing reaches to 92.4％ while the probability of competitive lane changing is less than 10％.关键词
