摘　　要：介绍了TransCAD中交通方式划分模型,总结了利用离散选择模型在TransCAD中实现交通方式划分的操作规程;结合实例阐述了离散选择模型在TransCAD中应用的步骤,并将预测结果与实际值以及回归模型预测值进行了比较分析。对比分析表明,结合TransCAD利用离散选择模型进行交通方式划分可较为科学、直观和简便地获得各交通方式分担率。The characteristics and applicability of the model for mode split in TransCAD were discussed. The observing problems and the critical parameters in applying the discrete model were analyzed. Also, the operation regulations using discrete choice model in TransCAD for mode split were summarized. At last, the detailed approach to estimating and applying the discrete model was presented in TransCAD with an example. The forecast results were compared with MNL and regression model. The result shows that the forecast result can be obtained by using discrete model for mode split with TransCAD in a scientific, intuitional and simple way.
