Millions of urban dwellers face difficulties owning a car because of congested and accident-prone infrastructure, sky-high parking fees, and high maintenance cost. The need for car ownership can be reduced by providing an efficient and effective car sharing system. In this paper, we propose an electric car sharing service system using mobile technology, which can be a substitute for fuel consuming cars. Our system will be helpful in saving the resources and the energy consumed in producing and owning cars as well as improving the quality of life in urban areas.
