Recent developments of interactive computer-graphics user interface for traffic simulation models are discussed. Each developed interface is using the capability provided by computer graphics to graphically "translate" the alphanumerical information needed and/or generated by the digital simulation program into a display with a more easily assimilated format. Such graphic capability enables the traffic engineer to reduce, or on occasion even eliminate, some of the difficulties associated with traffic simulation models such as extensive data preparation, tedious debugging, and voluminous printouts. Computer graphics aid in input data preparation, and debugging would achieve a greater benefit for the traffic engineer compared with applications like animation of traffic flow or output information display. Therefore, future research efforts should concentrate on the development of algorithms that use as little additional geometry data as possible and to generate sufficient network diagrams as needed by the simulation model. A typical example of this is to design an algorithm that would generate the lane-detailed urban street network mixed with freeways and their on-and-off ramps. The use of interactive computer-graphics user interface with traffic simulation models is relatively recent. Substantial efforts are still needed in research, development, and implementation of such a new technique.
