Abstract

In order to reduce the cost of demand responsive transit systems, this paper studies a grid hybrid transit service that integrates two modes of transportation: demand responsive service and fixed route service. An analytical model is developed that aids decision-makers in designing this hybrid grid network. The objective of the model is to determine the optimal number of zones in an area where each zone is served by a number of on-demand vehicles. The function of the on-demand vehicles is to transfer passengers to a fixed route line if the destination is to a different zone or to its final destination if it is within the same zone. The model trades off the cost to passengers, on-demand vehicles and fixed bus lines to determine the optimal number of zones. Two cases are analyzed to demonstrate the capabilities of the model in determining the optimal configuration for a given set of parameters.
