The development of interactive graphics displays for the Integrated Traffic Data System (ITDS) is described, and technical details on the hardware and software considerations, which, to a large extent, influenced the end product are provided. ITDS is a user-friendly, data base-driven interface to various traffic simulation and signal timing optimization programs. Although very useful and effective, ITDS relies extensively on the user's capability to load and maintain traffic data from queueing menus. By adding the graphics display interface, users are now able to efficiently load and maintain the data base, draw schematic displays of the data stored, efficiently determine their integrity, and significantly improve the quality of the data used as input to traffic models. This paper is oriented towards individuals who are, or will be, users of ITDS and traffic models, and individuals who are involved in the development of graphics software for transportation applications.
