弹性需求下的双向混合交通需求预测组合模型

摘要

Based on the operational features of the mixed driving on two-way urban road and the actual traffic network in China,a forecasting combinational model is builded for the two-way mixed tr affic demand under the elastic demand by means of Logit path choice model. Its firstorder equivalence is proved,its specific algorithm is given and the example which shows that the model is effective.%基于我国城市道路双向混合行驶现状及实际交通网络的运行特点,借助Logit路径选择模型,建立弹性需求下双向混合交通需求预测组合模型.证明了模型的一阶条件等价性,给出其具体的求解算法并用算例说明该模型是有效的.
