Abstract. This paper presents a model for determining the sufficient density of alternative fuel stations. The model extends a previous model to incorporate both flow demand and the deviation distance, and provides a more appropriate framework for analyzing the density of stations. The service level is represented as the probability that the vehicle can make the repeated round trip between randomly selected origin and destination within a specified deviation distance. The density of stations required to achieve a certain level of service is obtained for three cases: fuel is available at both origin and destination, fuel is available at either origin or destination, and fuel is available at neither origin nor destination. The result shows how the deviation distance, the vehicle range, the trip length, and the refueling availability at origin and destination affect the sufficient density of stations.
