摘要：Abstract Traffic jam is a growing problem especially in big cities like Riyadh. Wherever, streets are congested with cars and the need of cost-effective system is increasing in order to reduce the traffic jam impact. At the same time, each car's capacity can take up to four persons but this capacity is generally underexploited. If we can take advantage of the free space in each car, this will lead us to its best use with an optimal equation for achieving: fewer cars in the streets with more number of passengers. In this context, our mobile application “Where are you ?” is proposed as a solution that can help solving traffic jam problem. “Where are you ?” is a real-time application, which connects for free people living in the same city and having the same travel needs. Users ride-share their cars, based on the GPS position of the requester, the system searches the nearest and available car on the way of the requester. The system provides feedback and favorite driver's features, so that will help to recommend the best available driver. Our system is developed for android phones. It is considered as a social media since it provides communications between individuals or groups. Our application is based on trusted users. Users are authorized to register as part of a university or a company group or validated by their administrator. A “female only option” is also provided by the system. Our application is environmentally friendly because it provides carpooling service, which reduces carbon emissions, traffic jam, and the need for parking spaces.
