Paratransit Service Optimization for Special Events

Paratransit services can be useful for special events, especially when private vehicles are discouraged from approaching the event locations. During the Athens 2004 Olympics, such a shuttle service was planned to connect major Athens spots with athletic complexes. A mixed nonlinear integer programming model is developed for jointly obtaining optimal headways and vehicle types for such a paratransit service, given demand, resource, and travel time constraints. The model is incorporated into a user-friendly Microsoft Excel–based interface. An application of the model to the Athens 2004 Olympics and its results are presented and discussed.
