ANALYTIC EQUILIBRIUM MODEL FOR DIAL-A-RIDE DESIGN
Dial-a-ride is a demand-responsive transportation system in the experimental stages of development. Previous analyses of the system have been dominated by relatively expensive, supply-oriented simulation models and crude, insensitive demand predictions. This paper presents an analytic equilibrium model that has minimal data and computational requirements and is suitable for use in designing future dial-a-ride systems. The model is used to test the sensitivity of level of service and net operating cost to changes in demand model parameters and fares. The results demonstrate the important effects of decisions such as fleet size, service area, and fare levels on the economic and noneconomic prospects of a potential dial-a-ride system. In dial-a-ride as in many other transportation systems, the inter-relations between design parameters and demand response are so complex that only an equilibrium model can predict the impacts of a specific design.
