Bus Allocation With Time Dependent Conditions Considering Crowding

摘要

This report addresses the determination of the frequency of service on each route during each period of the day. The objective is to develop a mathematical representation of this frequency determination. An optimization model is presented which incorporates the following problem attributes: (1) The key input data--demand for service, operating costs, and travel times--are all time dependent. (2) Passengers' costs are expressed in terms of waiting times, as well as in terms of the inconvenience caused by crowding on the vehicles. (3) Realistic operating constraints on subsidy, vehicle fleet size, and vehicle capacity.
