INTERACTIVE GRAPHICS IN HIGHWAY DESIGN

The Texas State Department of Highways and Public Transportation has an automated photogrammetric data-acquisition system that uses aerial stereophoto digitizing systems, which are integrated through video graphics, in order to produce digital models of the geographic areas on which highway facilities are proposed to be constructed. Highway design engineers then use a computer-supported system of engineering programs in order to interact with the digital model and proceed through the necessary logical processes at remote terminals to superimpose the design of the proposed highway facility on the existing terrain and develop the required engineering criteria for construction of the facility. The graphics related to these processes can be handled in either the video or hard-copy mode. In addition to generating the usual graphics provided in a set of construction plans, the system allows the designer to view three-dimensional displays of the proposed roadway and bridge structures as they will appear to the driver when completed. The system is applicable to all similar engineering problems, such as airports, waterways, streets, and utilities. The purpose of this paper is to discuss how the automated data-acquisition system functions and how a remote network of video graphics terminals supports the highway design process in a distributed data-processing environment.
