This paper documents the results of a case study in which an interactive graphics system was applied to solve a bus transit design problem. The aim of the study was to gain insights into the applied use of the interactive graphics system and to assess its utility as a practical sketch-planning tool. The particular system used was the Interactive Graphic Transit Design System (IGTDS), and the problem to be addressed was the design of a bus system in the Southfield-Jeffries Corridor in southeast Michigan. The study consisted essentially of a data-base development phase and a system-application phase. The results of the case study are reported in terms of (a) the user requirements for data-base development, (b) the general on-line problem-solving experience by using IGTDS, (c) the efficiency characteristics of the IGTDS design process, and (d) the on-line times and costs associated with IGTDS operation. The major findings were that IGTDS was simple to use, that the application costs were relatively low in terms of both data-base development and system operation, and that the IGTDS design process was quite efficient in generating design solutions to the relatively complex bus transit problem (i.e., 81 designs in 24 h of on-line time). These findings suggest the strong potential of interactive graphics systems like IGTDS as practical and cost-effective sketch-planning tools. (Author)
