服务水平-运行效率-资源消耗传导下的 通道交通方式选择模型

分析研究运输服务水平、运行效率及资源消耗三者的互动影响机理，并构建相 关模型表征三者互动传导机制.用户对交通方式服务水平的感知程度影响其选择决策，用 户的出行需求直接影响交通方式的运行效率，运行效率的高低表征了资源被有效利用的 程度.在该互动传导机制下，构建基于出行链的通道交通方式选择MNL模型.以北京-西 安运输通道为案例，对模型进行验证.结果表明，普通铁路依旧承担着该通道内的主要运 输需求.

The Transportation Corridor Mode Choice Model Based on the Interaction Mechanism of Transportation Service Level,Operational Efficiency and Resource Consumption

This paper firstly analyzes the interaction mechanism of the transportation service level, the operational efficiency and the resource consumption. Relevant models are built to show the interaction mechanism between the three factors. The users select a mode of transportation always depend on their perception in the transportation service level. The user's travel demand directly affects the efficiency of a mode of transportation. This efficiency represents the degree of effective utilization of resources. Under the interaction mechanism, this paper builds a travel-based, MNL transportation choice model in a transportation corridor. This paper chooses the Beijing-Xi’an transportation corridor as a case to test the model. The results show that the ordinary rail still undertakes the mostly transportation demand in Beijing-Xi'an transportation corridor.
