项目摘要

The effects resulting from the traffic measures in a developmental region depend on its regional characteristics. That is, each inhabitant in each region evaluates the traffic measure differently each other, even if it is the same measure in every region. It mostly is caused by the subjectivity of human thinking. In this investigation, we propose to evaluate the interaction between physical services and the thinking which the people accept them in terms of fuzzy measures and fuzzy integral Such techniques are available to evaluate the ambiquity which we all possess in everywhere and every time. We examined three cases as follows :1) Evaluation of effects on inhabitant's living environment after construction of the bypass tunnel : The procedure and the method were developed on the evaluation of effects from the construction of road facilities In an empirical case, the inhabitants recognized not only direct effects but also indirect effects from the tunnel construction synergistically. T … More he effects were evaluated by Choque's integral.2) Use of a fuzzy theory technique for grouping of trips in the vehicle routing and scheduling problem : A technique of grouping trips on the basis of their similarity is presented. It is to be used in conjunction with any of the existing routing and scheduling models of demand responsive transportation vehicles. The composite similarity of the trip pair is computed by the fuzzy integral. It permits the selection of different similarity criteria, different values of weights among the criteria and the cut-off point of similarity grade depending on the requirements of the day. This is possible by expressing the similarity as a fuzzy relation. the technique can be used as part of prescreening of the original set of trips before any of the existing scheduling algorithms is applied.3) Traffic management simulation of the intersection in terms of driver's subjective information : The traffic flow on roads tends to be influenced in terms of drivers' attributes and their behavior to the traffic management.Thus it has been important to manage traffic control for keeping safety of car driving and harmonious traffic system. we propose a new idea to introduce drivers' subjectivity into Monte Carlo Simulation. the decision making system using fuzzy concepts make a number of right turned cars decrease, because it is compound of dirivers' attributes.

一个发达地区的交通措施所产生的效果取决于其区域特点。也就是说，每个区域中的每个居民对交通测量的评估彼此不同，即使它在每个区域中是相同的测量。这主要是由人类思维的主观性造成的。在这项调查中，我们建议用模糊度量和模糊积分来评估实体服务与人们接受服务的思维之间的相互作用，这种技术可以用来评估我们随时随地都拥有的犹豫感。1)绕行隧道建设对居民生活环境影响的评价：在一个实证案例中，建立了道路设施建设影响评价的程序和方法，居民既认识到隧道建设的直接影响，也认识到隧道建设的间接影响。T…采用模糊理论方法对车辆路径与调度问题中的出行进行分组：提出了一种基于相似程度的出行分组方法。它将与任何现有的需求响应型运输车辆的路线和调度模型结合使用。通过模糊积分计算出行对的合成相似度。它允许根据当天的要求选择不同的相似标准、标准中不同的权值以及相似等级的分界点。这可以通过将相似性表示为模糊关系来实现。3)基于驾驶员主观信息的交叉口交通管理仿真：道路上的交通流量往往受到驾驶员属性和行为的影响，因此，对交通控制进行管理对于保障汽车驾驶安全和交通系统的和谐具有重要意义。提出了在蒙特卡罗仿真中引入驾驶员主观性的新思路。采用模糊概念的决策系统由于是驾驶员属性的复合体，使得右转车辆的数量减少。较少
