A Study of the Design Support System for Preservation, Maintenance, Restoration, and Renewal of Roads

(1)研究者试图构建设计信息数据库系统，为道路的保护、维护、修复和更新设计提供帮助。这些信息是从196个实际道路设计案例中提取出来的，并以文字描述和图形图像的方式进行记录。从对道路功能、道路空间、环境、景观和道路建设管理的影响等方面对数据库内容进行了分析，并将其分为16类。(2)在数据库系统的基础上，尝试构建支持设计师构思设计形象的形象配置辅助系统。研究了图像图像处理系统的理论、可能性和问题，描述了图像图像处理系统的基本思想、方法和系统组成。(3)在数据库系统的基础上，尝试构建由作为事实的知识（数据）和解决问题的规则组成的知识库系统。该系统被认为是有用的：(a)指定设计场地的背景，(b)澄清设计的主题问题，目标，效果等，(c)识别设计中物理元素的组成和空间安排的问题结构。

(1) The investigators have attempted to construct the database system of design information which contributes to design roads for preservation, maintenance, restoration, and renewal. The information was extracted from 196 cases of actual road design, and was recorded by means of verbal descriptions and pictorial images. The contents of database were analyzed and classified into 16 categories in terms of effects or impacts on road functions, road space, environment, landscape, and road construction management.(2) Based on the database system, the image configuring aiding system, which supports for designers to conceive design images, was tried to construct. The investigators studied the theory, possibilities and problems of the system which deals with pictorial images for iconic image and image description for verbal image, and described fundamental ideas, methodology and system composition.(3) Based on the database system, the investigators made an attempt to construct knowledge-base system which consists of the knowledge (data) as facts and the rules for problem solving. The system is considered to be useful for :(a) specification of the context of the ground the design was placed,(b) clarification of the subject issues, the targets, effects etc.of the design,(c) identification of problem structure concerning composition and spatial arrangement of physical elements in the design.
