摘要: 针对常用出行方式选择模型对铁路到达旅客离站交通服务水平需求考虑不足的问题,分析了到达旅客离站交 通方式选择机理,定义了服务水平期望作为服务水平因素变量;改进了到达旅客离站交通方式选择模型以及效用函 数;根据成都东客站调查数据进行了模型验证。研究表明:服务水平指标参数β取值较低时,部分对于服务水平要 求较高的乘客可能会由公共交通方式转向私人交通方式;β取值较高时由于交通信息不对称,乘客不能做出最有利 的决策,使得部分公共交通资源没有发挥作用。

Abstract: Current traffic choice models lack the consideration of the arriving passengers' requirements of service levels when the railway is arriving at the station. In order to solve this problem , the alTiving passengers' off-site modes choosing mechanism was analyzed; the expectations of service level were defined as factor variables; and the arrlvmg passengers' off-site modes as well as the utility function were improved. Finally , the model was validated with the survey data obtained by Chengdu East Railway Station. The results show that , when the value of service level indicator parametery is low , those passengers with higher service level requirements will shift from public transpOltation to private transportation; whenβIS high , passengers can' t make the most profitable decision because of traffic information asymmetry , which causes part of the public transportation resources do not work.

Key words: traffic engineering, service level expectations, improved utility function, nested logic (NL) model
