Roundabout Animation (Traffic Circle Animation Report for Years 10 and 11)

摘要

This report describes work done on a roundabout animation program during 1998 and1999. The roundabout animation program began as an undergraduate class project and was presented in February 1998 in the New England University Transportation Center report 'Animation of Traffic through Roundabouts'. This new report presents the work funded by the Year 10 (97/98) grant Traffic Circle Animation (Project No. MEE10-2) and Year 11 (98/99) grant Data Collection for Traffic Circle Animation (Project No. ME11E-2). Undergraduate students were involved in all of these modifications. The program is based on the principle of an autonomous agent. The cars are programmed to speed up, to slow down, and to enter to 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.
