Described in this paper is the development of an interactive computer graphics (ICG) system, named GTRAF, that provides users with a new and highly efficient methodology for analyzing results generated by the NETSIM microscopic traffic simulation program. This tool may be executed on microcomputers (PCs) with graphics capabilities or on any larger computer that supports Fortran and graphics. Portability of the software is assured through the adherence to ANSI Fortran and the Graphics Kernel System (GKS) standard. Following a discussion outlining the need for and use of ICG systems for the traffic engineering profession, an outline is provided of the concepts and objectives guiding the design of GTRAF, as well as a description of its logical structure. The reader is then walked-through an ICG session with GTRAF. Photographs of the displays are provided to illustrate the process.
