Analysis of Sufficient Density of Alternative Fuel Stations Using Rectilinear Distance

This paper develops a model for determining sufficient density of alternative fuel stations. The service level is represented as the probability that the vehicle can make the repeated round trip between randomly selected origin and destination. Distance is measured as the rectilinear 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 demonstrates how the vehicle range, the trip length, and the refueling availability at origin and destination affect the sufficient density of stations.
