A sketch-level method for estimating bus deadhead costs that can serve as an input to high-level decision-making processes is described. In a recent analysis for TransLink in Vancouver, British Columbia, Canada, this methodology helped to quantify the total net change in deadhead costs associated with various location options. A geographic information systems (GIS) tool was used to calculate the shortest path among alternative maintenance base locations and start and end points of bus routes. Shortest-path calculations were based on estimated travel speeds, congestion, and known geographic constraints provided by the operator. Total deadhead-related costs were then estimated for each of the three maintenance base location options under consideration. The difference between these costs served as one component in the decision-making process, along with other factors such as property acquisition and construction cost. This analysis serves as an example of how GIS use can provide a low-cost sketch-planning tool to inform investment decisions.
