Abstract
The authors tried to construct Road Design Aiding Computer System, which aids configuring design image, solving design problems, design analysis and so on, and which contributes to creat better design solution. The system consists of five major subsystems as follows: (1) design information database system, (2) image configuring aiding system, (3) problem solving system, (4) design analysis aiding system, (5) landscape simulation system. In this paper the authors focused on (1) and (2) and described fundamental idea, composition, some detailsof them. Applications showed that the system appeared to be useful without missing our aims.
