LOCATION SELECTION OF CHARGING STATIONS FOR BATTERY ELECTRIC VEHICLES IN AN URBAN AREA

2Every day countless miles are driven on the millions of miles of roads. This general trend continues to climb and it has led to an increasing demand in the diminishing oil supply and an increase in greenhouse gas production. Battery electric vehicles are emerging as an alternative to internal combustion engine based vehicles. As these vehicles enter the consumer market, the supporting infrastructure, such as charging stations, must be provided to reduce the driving range anxiety due to limited battery power and a long charging time. The readiness of this fundamental infrastructure is critical to the future market growth of such vehicles. The main objective of this paper is to determine the number of charging stations needed and the ideal locations to put them in order to meet the charging demand in an urban area. In this study, we developed a facility location model aided by a GIS based geometric reasoning method to help resolve the problem. By means of integrated modeling and mathematical optimization, it is demonstrated that the proposed model is capable of selecting proper locations for electric charging stations based on constraints in a given socioeconomic environment.
