STUDY ON THE USE OF AN INTERACTIVE VISUAL DISPLAY UNIT IN ROAD DESIGN

STUDIES UBER DEN EINSATZ EINES INTERAKTIVEN BILDSCHIRMSYSTEMS IM STRASSENENTWURF

The investigations were carried out on a Control Data Corporation (CDC) visual display unit (VDU) system. The aim was to develop the basis for an interactive on-line system, with reference to its applicability to handling design work in road construction, particularly in optimization program systems. As a basis a set of experimental programs was established, called INTAK (interactive design room), which enables problems in road design to be handled. The study contains an analysis of the possibilities for using an interactive VDU system in road design, and an introduction to the CDC 1700 system with a general outline of its characteristic properties. The experimental INTAK program handles some typical design tasks within the framework of a preliminary investigation. With the program, a series of illustrations demonstrates the operation of the VDU. In short, the essential elements of interactive VDU systems are described, together with the weaknesses and limitations of the DCD systems and notes on the construction of interactive VDU program systems. Recommendations are also made for the use of interactive VDU systems in optimization program systems. The study shows that interactive VDUs can be used successfully in many areas of road construction design. However, the expenditure on hardware and software, particularly for the interactive control of large program systems, e.g. for optimization, is very high. For this reason the type of system where this approach can be put into operation with very little delay is that where an interactive VDU with its own independent programs can be used as a supplement to existing program systems. /Author/
