CALS-oriented standardization of digital road design drawings

Standardization of information is required for construction to realize the exchange and sharing of information. This paper proposes a technique for standardizing digital drawing with a CAD system for road design. The technique uses CAD and compatibility of data in Japan; layer information, line styles, color and figure drawing operations, are standardized. Moreover, a field experiment was carried out to confirm the technique's applicability to designing and usefulness for drawing. The result verified effectiveness of the technique.
