tudy on applicability of panel data for transportation planning

本研究系以追踪调查法进行旅游行为分析。我们评估其适用性/效率经验，通过检查一些实际的交通规划问题。该项目包括两个阶段：（a）审查现有的小组调查技术，（B）利用调查数据进行实证评估。(a)回顾现有的调查方法，除了在欧洲和北美进行的调查外，还在日本进行了与交通规划和出行行为分析相关的调查。通过调查数据进行实证分析，可以证明在交通规划中可以应用调查数据。研究的面板分为三种类型：1）短期面板，主要关注路线和/或出发时间的选择; 2）中期面板，评估新设施对交通方式选择的影响; 3）长期面板，根据家庭生活阶段描述行为特征。并对使用面板调查数据和标准横断面调查数据进行了比较。

This research project concerns travel behavior analysis with panel survey. We evaluate its applicability/efficiency empirically through examining some actual transportation planning issues. The project consists of two phases : (a) review of existing panel survey technic, (b) empirical evaluation using survey data.(a) Review of existing panel survey technique considers panel surveys concerning transportation planning and travel behavior analysis, which include surveys conducted in Europe and North America as well as the panels our project team have been conducted in Japan.Empirical evaluation using survey data shows evidences of applying panel data for transportation planning. The panels examined are categorized into three types : 1) short-term panel, which focuses route and/or departure time choice, 2) mid-term panel, which assesses impacts of new facility on modal choice, 3) long-term panel, which describes behavior characteristic depending on household life-stage.We examined appropriate type of panel survey for specific issues of transportation planning. Comparison between using panel survey data and standard cross-sectional survey data is also made.
