Finding efficient driving directions has become a daily activity and been implemented as a key feature in many map services like WMS, Google and Bing Maps. A fast driving route saves the time of a driver and also energy consumption (as most gas is wasted in traffic jams). GPS-equipped taxis can be regarded as mobile sensors probing traffic flows on road surfaces and taxi drivers are usually experienced in finding the fastest (quickest) route to a destination based on their knowledge. The authors explore the smart driving directions from the historical GPS trajectories of a large number of taxis and provide a user with the practically fastest route to a given destination at a given departure time.
