| Abstract: | Under the background of 2013 CUMCM Contest A, traditional traffic flow model is proposed to research lane is occupied impact on urban road capacity. First, assuming a model. Secondly,modeling and solving models. Based on traffic flow wave theory, traditional traffic flow model is established to analyze the queue and dissipation process, to discuss mode of transmission assembly wave and evanescent wave, to get the vehicle queue length x and accident dissipation time 7＊ expression. At last, model checking show this model has a certain stability and robustness. |
