公路运输通道内的车辆出行路径选择模型及应用研究

Research on Model of Selecting Travel Route of Vehicle Within Highway Transport Corridors

考虑到影响运输通道内车辆出行路径选择的因素较为复杂 ,而现有的出行路径选择模型对多因素、微观指标的反应不敏感 ,本文利用随机效用理论建立通道内的车辆出行路径选择微观模型 ,并以安徽省沪蓉通道高界段为例进行模型的辩识和参数的标定 。

Considering complicated factors,which impact on vehicle travel characteristics within highway transport corridors,existing model of selecting vehicle travel route is not sensitive to impact of multi-factors and micro-index.The author applies random effect theory to establish a model of selecting vehicle travel route within a corridor under competitive conditions,and utilizes the data of traffic survey to determine and prove model parameters in travel route selection.Practice indicates the model objectively reflects traffic distribution within a highway transport corridor and how relative factors impact on it ,the research results will have important influence on highway comstruction and operation management decisions.
