Transport networks are increasingly faced with the problems of congestion externalities which tend to reduce the overall performance of networks. Thus, the advanced traveler information systems have been investigated in many countries as high-tech approach top aid drivers more informative route choices and to alleviate increasing levels of traffic congestion on networks. This research tried to design a prototype model for route navigation systems. The research subjects can be largely divided into three subjects in order to carry out the project effectively. The subjects include :1) To develop a new analytical framework for traffic equilibria with incomplete information. The main research efforts are devoted to the question of whether drivers can learn rational expectations from repeated observations of traffic conditions in a stationary environment. We investigated whether drivers can learn how to from rational expectations using standard Baysian estimation techniques.2) To design the traffic information systems for route navigation. This subject addresses to the question of whether route guidance information can covey substantial information to drivers even if drivers behave with rational expectations about their environment. The authors try to propose an analytical framework for investigating the informational role of route guidance information.3) To measure the economic values of traffic information systems. This subject oriented to present a unified framework to measure the economic values of information systems for route navigation. Welfare measurement is made by use of random utility models with rational expectations. Two alternative indices to measure the economic values of informational messages are proposed.

传输网络面临着越来越多的拥塞外部性问题，这往往会降低网络的整体性能。因此，先进的出行者信息系统在许多国家得到了研究，因为高科技方法有助于司机做出更多信息丰富的路线选择，并缓解网络上日益严重的交通拥堵。本研究试图设计一个路线导航系统的原型模型。为了有效地实施该项目，研究对象可以大致分为三个主题。研究内容包括：1)建立不完全信息条件下的交通均衡分析框架。主要的研究努力致力于这样一个问题，即司机是否能够从对静止环境中的交通状况的反复观察中学习理性预期。我们调查了驾驶员是否能够学习如何使用标准贝叶斯估计技术从理性预期中学习如何设计路线导航的交通信息系统。本课题研究的问题是，即使驾驶员对周围环境有合理的期望，路线诱导信息是否能够为驾驶员提供大量的信息。试图提出一个分析框架来研究路径诱导信息的信息作用。3)测量交通信息系统的经济价值。本课题旨在提出一个统一的框架来衡量路线导航信息系统的经济价值。福利测量是利用理性预期的随机效用模型进行的。提出了两种替代指标来衡量信息信息的经济价值。
