Ride sharing is a service that arranges one-time shared rides on very short notice. This type of carpooling generally makes use of three recent technological advances.
1-GPS navigation devices to determine a driver’s route and arrange the shared ride.
2-Smartphones for a traveler to request a ride from wherever they happen to be.
3-Social networks to establish trust and accountability between drivers and passengers.
Transportation experts have called these services “ride sourcing” to clarify that drivers do not share a destination with their passengers; the app simply outsources rides to commercial drivers. Examples of these “ride sourcing” companies are Fill Car, Uber, sidecar, Lyft, taxi and more.
