摘要
提出了对已知流量的路段数少于OD对的对数的路网进行OD推算,利用LOG IT概率多路径选择模型,建立已知流量路段的分配模型,采用迭代算法对其进行求解,并对结果进行分析,提出了大型城市网路OD推算步骤。
This paper has solved the problem of OD estimation while the number of the ways with the known flux is less than that of the OD pair. It establishes the distribution model of the ways with the known flux, using Logit probability multi-route chosen model. Then, it solves this model with iterative arithmetic. Finally, it analyzes the results and puts forward the steps to the OD estimation of the large city＇s network.
