This paper discusses an elementary traffic simulation model developed by the University of Utah. It consists of two intersections operating with fixed time traffic signal controllers. Vehicles are introduced into the system using a uniform arrival distribution. A simple car following model is used to move the vehicles through the network. The model can also be used as a visual scheduling and planning transit tool (VISPLAN). It will allow the transit planner to examine specific high volume transportation corridors; and when deemed desirable, the time schedule of individual buses can be changed to reduce wait time for transfers at critical route intersections. Future phases of model development will include calculation of the total wait time for transfers for all passengers in the system, which will allow planners to evaluate proposed schedule changes interactively as the changes are input to the system. The use of computer graphics has not been limited transportation systems. Urban designers have used visual simulation to build a three-dimensional scale model of Salt Lake City's Central Businees District to visualize the spatial relationship of new buildings which are proposed, or already underway, to those which already exist. Further development of the existing programs and development of some new applications of computer graphics are included in the program's future plans.
