In response to Ford taxi cab challenge we decide to build a solution for helping taxis to optimize their job, clients to quickly find taxi based on its position and its destination. To make it work we gather informations about passengers and taxis. In fact they share their destination and empty seats, we match it with others clients requests. We provide distance, time and cost estimations for the trip. In future we'll users data and Artificial Intelligence to optimize user's requests and build decisionnal statistiques. Therfore user will be able to choose his trip in terms of cost or duration.
