Abstract: The study on traffic impact of highway accident plays an important role in highway incident management. In the study, the shockwave theory as a foundation, the accumulation and dissipation process of the accident upstream location on two-lane highway was analyzed. According to the numbers of impacted lanes, the clean up time and the upstream traffic flow, a mathematical model named highway traffic accident impact model was established. By numerical models analysis and professional microscopic traffic simulation software under the same traffic conditions, the result shows that the model is ideal for evaluating traffic impact of highway accident for its small deviation about 5% and efficient calculating.
