BUBLS : a mixed integer program for transit centre location in the Lower Mainland Willoughby, Keith Allan
Abstract
A mixed integer optimization model is developed to determine both the optimal location of transit centres to serve BC Transit's Lower Mainland route network and the optimal allocation of buses to those centres. The existing five transit centres are explored as well as five candidate facilities. The model considers nonrevenue transportation cost (deadhead), capital cost of constructing candidate transit centres and the salvage values of existing centres. A linear regression is generated to produce the travel times from the terminus of a route to potential transit centre locations. The optimal solution is determined, resulting in potential annual savings of over $560,000 compared to the current location-allocation strategy. Various experiments are performed to examine the sensitivity of model parameters and to determine the effect of different planning scenarios. The effect of the optimal solution on driver relief is considered. Conclusions as well as directions for further research are offered.
