摘　　要：为了量化综合交通信息对小汽车通勤者的诱导效果,实施网络调查获取出行行为数据,分析了调查数据的统计特性,并对比有无综合交通信息时通勤出行链的时间、空间和结构特征,然后,基于SP数据建立通勤者在综合交通信息条件下出行选择行为的网络广义极值模型(NGEV模型),并利用BIOGEME软件包进行求解。通过分析参数标定结果,得到如下结论:综合交通信息下通勤者进行复杂出行链选择公共交通的概率更低,小汽车通勤出行链(私人交通模式)在泊位数充足的情况下转向其他交通模式的倾向性较明显。In the context of integrated transportation information,the content of the information service was designed,and an online survey was carried out.In order to learn the impacts of integrated transportation information,according to the statistical data with and without integrated transportation information,the commute trip chains' temporal, spatial and structural characteristics were compared.Then,a network generalized extreme-value model(NGEV model) was developed to study the commute travel behavior under the integrated transportation information based on SP data,and the BIOGEME software package was applied to calibrating the model.By analyzing the estimation results,some conclusions were obtained:when exposed to integrated transportation information,commuters with complicated trip chain tend to give up public transport,and the commuters with car trip-chain(private travel pattern)are inclined to shift to other travel patterns if parking space is enough.
