Development of Knowledge Information Model for Highway Route Design

This paper shows a design structure schema for highway route design based on the conceptual pyramid information model and the connector model in previous studies. In the design structure schema, the design process is classified into four stages: Conceptual Design, Outline Design, Basic Design, and Recursive Design, and it shows that the highway design process can be viewed as a function of the designer’s thought process. Moreover, a method for analyzing the fluctuation in highway distance was proposed. A distance-conversion table for each measurement that lengthens the highway can be linked to the dispositional information. Using this method, we can start compiling knowledge from the beginning about changes in distance and will be able to reproduce the route-selection process in a system.
