Dynamic ridesharing


Dynamic ridesharing

dynamic ridesharing (also known as instant ridesharing, ad-hoc ridesharing, real-time ridesharing or dynamic carpooling), denotes a special implementation of a carpooling service which enables the formation of carpools on very short notice. Typical for this type of carpooling is
* arrangement of one-time trips instead of recurrent appointments for commuters,
* the usage of mobile phones for placing carpooling requests and offers through a data service,
* automatic and instant matching of rides through a network service,
* The network service compensates the driver by an integrated billing system.

While there exist plenty of carpooling agencies for commuters, there is no large scale operation of an instant ridesharing service today. However, pilot projects have proven the technical feasibility of such service.

Advanced Concepts, only described in publications so far, explore options for
* position tracking of users using GPS enabled devices to avoid the necessity to manually enter the current position when requesting/offering a ride. This also allows the use of fleet management systems for vehicle tracking and guiding, e.g. in case passenger pickup requires a short detour. Ideally, the navigation system integrates a ridesharing functionality.
* multihop matches: passengers change cars to get to their final destination
