Optimization of Highway Geometric Design Process for Computer-based Design

摘要

In the design process, a virtual model, which can be called an information structure, is built up using information in a virtual space. The information structures used in construction are propagated as a design progresses. However, this process has not been sufficiently analyzed and optimized for computer-based design. This paper summarizes the concept of information propagation in the construction process and analyzes the information flow in the process of highway design. The analysis of the highway design process clarifies the problems with the conventional paper-based method of highway design. The systematic flow of a computer-based highway geometric design method is shown, and the need for a paradigm shift in the highway design method and the relationships between designers, system developers, and verifiers are discussed.
