Comparison of Static Vehicle Flow Assignment Methods and Microsimulations for a Personal Rapid Transit Network

This article describes Personal Rapid Transit (PRT) is a new, fully automated public transportation system characterized by small-size vehicles running on exclusive guideways. The authors focus on the use of a static assignment method for PRT. They stress that, because of its automated, on-demand service, PRT must be able to automatically reroute empty vehicles after use in order to supply stations with waiting passengers. Therefore, any PRT traffic assignment must take into account the flow of empty vehicles as well as the flow of vehicles with passengers. The authors use linear programming models to come up with assignment methods. They describe the results shown when one of the assignment methods was applied to a realistic PRT network, and the statically assigned flows compared with averaged link flows produced by a PRT microsimulation. They conclude that the proposed static assignment method is not only useful to identify capacity bottlenecks of the planned PRT network but also serves to benchmark the microsimulator's vehicle management algorithms.
