In recent years, because traffic congestion tends to be more serious and electric information and communication technology is kept on improving, providing drivers traffic information is regarded as one of possible strategies to facilitate the efficient use of road network and relieve traffic congestion. But because of complexity of interrelation between travel behavior, traffic flow and real time traffic information, the effect of providing traffic information on traffic condition has not been confirmed yet.Therefore this research project attempts to build the dynamic network simulation system that can explicitly describe this interrelation and estimate influences of providing information. This system consists of three main sub-models : route choice model, dynamic traffic flow model and information model. In this project, we conduct the experimental analysis approach in which participants are repeatedly asked for their hypothetical route choices to analyze the route choice mechanisms o … More f drivers with real-time traffic information. This project integrates the route choice model based on the results of this experiment and the dynamic traffic flow model developed by this research group into the dynamic network simulation system.In this research project, drivers are divided into three groups : a group of drivers with fixed route, a group of divers who choose their routes based on their travel experiences only and a group of driver with real-time information. A few cases of numerical experiments on small network are conducted so as to test the validity of this system performance. The following useful knowledge is obtained through this research project. 1)As the component ratio of drivers with traffic information becomes larger, the average travel time for all the drivers decreases ; the direct merit caused by providing information to drivers with information, however, decreases. 2)There is strong possibility that providing information of which quality is low makes traffic condition worse.

近年来，由于交通拥挤的趋势日益严重，以及电子信息和通信技术的不断改进，向驾驶员提供交通信息被认为是促进道路网络有效利用和缓解交通拥挤的可能策略之一。但由于出行行为、交通流和真实的实时交通信息之间的相互关系复杂，提供交通信息对交通状况的影响尚未得到证实，因此本研究计划试图建立一个动态网络仿真系统，能够明确地描述这种相互关系，并评估提供信息的影响。该系统由三个子模型组成：路径选择模型、动态交通流模型和信息模型。在本研究中，我们采用实验分析的方法，反复询问参与者的假设路径选择，以分析参与者的路径选择机制。 ...更多信息 f司机实时交通信息.本研究将基于实验结果的路径选择模型与本课题组开发的动态交通流模型集成到动态网络仿真系统中，将驾驶员分为三组：固定路径的驾驶员组、仅根据行驶经验选择路径的驾驶员组和实时信息的驾驶员组。在小规模网络上进行了几种情况的数值实验，以检验该系统性能的有效性。通过本研究项目获得了以下有用的知识。1）随着拥有交通信息的驾驶员的构成比变大，所有驾驶员的平均行程时间减少，但向拥有信息的驾驶员提供信息所带来的直接效益降低。2)提供低质量的信息很可能使交通状况恶化。少
