• Abstract:
  Conventional bus service (with fixed routes and schedules) has lower average cost than flexible bus service (with ; demand-responsive routes) at high demand densities. At low demand densities flexible bus service has lower ; average costs and provides user-friendly door-to-door service. Bus size is interrelated with service type since large ; buses have lower average cost per passenger than small buses at high demand densities, and vice versa. The ; service type and vehicle size decisions are jointly optimized here for a bus transit system connecting a major ; terminal to local regions. Bus sizes, conventional route spacing and flexible service area are the decision variables in ; a proposed algorithm which optimizes a multi-dimensional nonlinear integer optimization problem. Numerical analysis ; shows how the proposed Variable Mode & Multiple Fleets Operation can reduce total cost compared to a Single Fleet ; & Single Mode operation. The sensitivity of results to important parameters is explored. ; Additional details on the problem and its formulation, the solution methods employed, and the results obtained are ; provided in the following report. This report has been submitted for publication by a transportation journal under the ; title “Mixed-Fleet Variable-Type Bus Operation” and is currently under review.
