多方式交通信息下节假日活动链重构机理研究

多方式交通信息是影响节假日出行重构规律的重要因素.本文以节假日活动链为研究对象，基于分层决策理论探究多方式交通信息下节假日活动链的重构机理.利用 2012 年节假日出行行为调查数据，综合考虑出行者个人属性、信息属性及活动-出行行为的历史依赖性，构建了基于节假日活动链重构机理的结构方程模型.研究结果表明：多方式交通信息对节假日活动和出行行为有显著的负效应，出行者受信息影响越大，活动链的时空复杂性和结构复杂性越低.在多方式交通信息的作用下，节假日活动链的重构方向并不是随机变化的，而是在一定程度上依赖于过去的行为习惯，并朝着与之相关的方向发展.

Reconstruction Mechanisms of Holiday Tour under Integrated Multimodal Travel Information Service

Integrated multimodal travel information (IMTI) is a key factor for holiday travel reconstruction. This paper takes holiday tour as the study object, and investigates the reconstruction mechanisms of holiday tour under IMTI service based on the theory of decision hierarchy. An activity-based survey was conducted during the holiday in 2012, and a structural equation model was developed based on the survey data. The estimated model takes personal attributes, information influence and history dependence of activity and travel needs into account. Results suggest that IMTI has a significant negative effect on the holiday activity and travel behavior. The more IMTI perceived by the traveler, the simpler the tour spatiotemporal and structural complexity will be. In addition, under the influence of IMTI, reconstruction direction of holiday tour is not random, but relies on the past travel behavior or habit.
