项目摘要

(1) In developing a transportation network plan, it is generally required to handle bulky numerical data as well as various maps, in order to understand planning condition of a study area. However, as the volume of data increase, not only it requires a lot of times and efforts to handle them, but it becomes difficult to realize problems hidden under those data, especially to analyze those data in relation to a location of specific sites that data represents. For the purpose of eliminating those technical difficulties, the team has studied to develop computer mapping techniques. In the process of study, transportation network planning for the Kumamoto urban area has been taken as the case.(2) The study has developed two types of programs : firstly, analytical tools such as to evaluate accessibility of people by car or by bus, and to allocate traffic flow using I-A algorithm : secondly, mapping tools to present basic data or results of analysis, visually. Though a work station can be use … More d for both types of programs, the study has used personal computers that had been linked to the work station for data editing and graphic presentation. We made such arrangement in order to reduce occupation time of faster system by works that human interaction or interference are frequently required.(3) The study has edited, such data as the census district base population census data, or various network data that transportation planning committee had constructed, for the system mentioned above. In addition to basic analysis of those data, the case study has showed that it is urgent to complete ring trunk roads and new bus service lines that correspond trip demands for circumferential direction. It also evaluated impacts of planned ring road for the year 2000 on traffic flows pattern.(4) Those case study also has showed that computer mapping technique can be used as an effective tool for planning studies, because it makes easier to understand bulky numerical data in relation to spatial structure of the study area. It also will be able to overcome such conflicts in graphic presentation as that planner needs quick and continuous presentation of both total image of the study area and detailed image of the part of the area.

(1)在制定交通网络规划时，通常需要处理大量的数值数据和各种各样的地图，以了解研究区域的规划情况。然而，随着数据量的增加，不仅需要大量的时间和精力来处理这些数据，而且很难发现隐藏在这些数据下的问题，特别是很难将这些数据与数据所代表的特定站点的位置进行分析。为了消除这些技术上的困难，该小组已经研究开发计算机制图技术。在研究过程中，以熊本市区交通网络规划为例。(2)研究开发了两种类型的方案：一是分析工具，如评估人们乘坐汽车或公共汽车的可达性，并使用I-A算法分配交通流量；二是地图工具，以可视化的方式呈现基本数据或分析结果。虽然工作站可以用于这两种类型的程序，但研究使用的是与工作站连接的个人电脑，用于数据编辑和图形展示。这样的安排，是为了减少经常需要人的交互或干扰的工作对较快系统的占用时间。(3)本研究为上述系统编辑了普查区基础人口普查数据或交通规划委员会构建的各种网络数据等数据。除了对这些数据的基本分析外，案例研究表明，迫切需要完成符合圆周方向旅行需求的环形干线和新的公交服务线路。并评价了规划的2000年环城公路对交通流模式的影响。(4)这些案例研究还表明，计算机制图技术可以作为规划研究的有效工具，因为它更容易理解与研究区域空间结构有关的大量数值数据。它也将能够克服这样的冲突，在图形呈现，因为规划师需要快速和连续的展示研究区域的整体形象和部分区域的详细形象。少
