Abstract

In this article a significant relationship between vehicle (trip) assignments and garage location was found through a Detroit case study. From these results two conclusions are reached. 1. Vehicles should not be assigned to trips by mathematical models which do not consider the location of the garage that the bus will come from. Models which do group trips into blocks independently of garage location may result in block designs which have significantly higher deadhead costs than if the garage's location is considered. 2. Potential bus garage locations should be evaluated using a block design (vehicle assignments) which was designed for another existing site. The existing block design will have been created with the existing garage location in mind, hence biasing the block design toward existing sites. Therefore, the true picture of the potential costs of operating from a prospective site can not be obtained through existing vehicle assignments which do not consider the new location.
