摘　　要：通过调查大广高速衡大段断面交通量数据,对由于车型不同造成的路阻函数选取的不同进行了研究,选用Logit多路径非平衡分配算法进行交通量分配;并以MATLAB为数据处理软件平台,对新建交通分配模型进行了实例验证,并基于实测数据对模型结果进行了精度检验。结果表明,在此模型下得到的分配结果与实际结果吻合度较高。Based on the investigation of the traffic volume data of the Hengda section of Daguang expressway, this paper studies the different selection of the road resistance function caused by the different vehicle types, and selects the Logit multi-path unbalanced allocation algorithm to allocate the traffic volume. Taking MATLAB as the data processing software platform, the new traffic assignment model is verified by an example, and the accuracy of the model results is verified based on the measured data. The results show that the distribution results under this model are in good agreement with the actual results.
