Co-operative Research on the svstematization and application of Travel behavior model.

近年来，评估体系日趋多样化，评估动机和行为也越来越复杂。在对交通系统进行规划时，我们必须考虑这些现状，有效地使用出行行为模型，但目前已有的模型还不足以进行这些分析，因此对这些模型进行回顾和系统化，对于发展新的建模概念是非常重要的。确定了本研究的主要目的，即出行行为模型的理论体系化和应用。出行行为模型的理论系统化(1986)(1)回顾了迄今为止的行为模型，不仅在交通工程领域，而且在经济学、心理学、系统工程和管理学领域。在对交通规划问题进行分类的基础上，明确了模型所需要的信息和必要条件。我们考虑了两个问题：休闲旅行和市中心的商务旅行。出行行为模型应用研究(1987)(3)对出行数据和社会计量学数据进行整理，进行模型比较，并用不同的估计方法对一些具有代表性的模型进行估计。(4)通过对应用工作的回顾，我们发现其中的一些困难可以通过调查制度的改革来解决。(5)全体成员的讨论建议在未来的理论研究和实践研究中并行进行。

Recently valuation system is diversified, motive and behavior are more and more complicated. When we plan the transportation system, we must consider these current, using Travel Behavior Model effectively.However the models to date are not sufficient for thes analysis, it is quite important to review and systematize these models for the development of new modeling concept. We set the main purposes of this study such as theoretical systematization and application of Travel Behavior Model.1. Theoretical Systematization of Travel Behavior Model (1986)(1) To review the behavior models to date ,not only in the field of Transportation Engineering, but of economics,psychology,system engineering and management. Especially, we classified the disaggregated model,which can explain the decision making tree and criteria, and the entyopy model, which can analyze interaction among individuals.(2) After classified the transportation planning problems, we clarified the information required and requisites of model. We consider the two problems: recreation trip and business trip in downtown.2. Study on Application of Travel Behavior Model (1987)(3) To arrange the data of trip and socio-econometric conditions in order to model conparison.Using this, some representative models were estimated by alternative estimation methods. It was revealed that the difference between estimation methods were as much as that between models.(4) By review of the application works, we found that some of those difficulties could be solved by reformation of investigation system.(5) Discussion of all members suggested that in future theoretical research and a pplicational one would be carried out in parallel.
