| 摘 要： | 在对出行目的地空间分布特点进行分析的基础上,提出了减少选择枝个数的目的地小区分段抽样策略,该策略的应用减少了仿真的计算量.采用该抽样策略建立了基于贝叶斯理论的出行者出行方式和目的地联合选择模型.通过对该模型进行仿真计算,结果表明出行方式和目的地的联合选择模型能够有效地模拟出行者的行为选择.而且,联合选择模型的预测精度明显高于重力模型.因此,在分析出行者行为选择方面采用出行方式和目的地的联合选择模型是一种有效的方法.

| Abstract: | This paper analyzes the characteristics of the destination distribution of trips and proposes a stratified sampling strategy for travel mode choice.The stratified sampling strategy can reduce the size of the alternative set;thus,the computation burden of simulation is decreased.Using the stratified sampling strategy,a combined choice model of the trip mode and destination is developed based on the Bayesian theory.Simulations are carried out to verify the proposed model.The results show that the combined choice model of the trip mode and destination can efficiently simulate travelers＇ choice behaviors.Furthermore,the forecasting accuracy of the combined choice model is higher than the one of the gravity model.Therefore,the proposed model is a powerful tool with which to analyze travelers＇ behaviors in selecting the trip mode. |
