Abstract:This report describes work done on a roundabout animation program during 1997. The roundabout animation program began as an undergraduate class project and has evolved to its current state. The program is based on the principle of an autonomous agent. The cars are programmed to speed up, to slow down, and to enter the roundabout based on an acceptable gap length. That is, the gap between themselves and the cars around them. The actual gap is compared to an allowed gap that is based on vehicle speed and assumed driver response time. If necessary, the vehicle speed is adjusted. The cars travel through the roundabout following a randomly assigned path. Traffic flow values may be input into the program manually during initialization. During simulation, the cars enter and exit randomly based on these values. After the simulation, traffic count data and average delay data may be displayed. Sponsored by Department of Transportation, Washington, DC.
