TRANSPORTATION RESEARCH PART E-LOGISTICS AND TRANSPORTATION REVIEW
A heuristic procedure is developed to assign buses to transit centers (gara
ges) in such a way that all the buses on a particular route are assigned to
a single transit center. This research builds on an optimal mixed integer
programming location/allocation model that splits the bus assignments when
capacity limitations were reached at a transit center. The heuristic proced
ure adopts a two-step process: namely, assignment of all buses of a route t
o a unique transit center, then switching of routes to alternative transit
centers to enforce capacity limitations. The procedure is shown to still pr
ovide cost savings over current locations and allocations for the Vancouver
Regional Transit System (VRTS), Canada's largest urban transit network. (C
