A Push Service for Carpooling

Carpooling is a social service par excellence. Solidarity between people or within identified groups, contracting service and confidence in service when hazards can occur, safety of the service provided (not only the ICT information provided but also the operated travel when an itinerary path is computed), and sometimes confidentiality agreements or information exchanged, all these characteristics and values are features which are considered necessary to develop the use of carpooling. The use of carpooling is too confidential. It is struggling to reach a critical mass. Furthermore, the democratization of the carpooling service faces the difficulty of access to a critical mass of offers (empty seats) to look forward a request. In this paper we define and provide a push service to carpooling. This push service brings more opportunism. So the instant processing of an offer or need transportation, explicitly formulated, or implicitly and partially formulated, that leads to intelligent use. Log management, knowledge of the operating environment in real-time, enabling the functionality of the service push, all these features make up a process of linking supply and demand as a prerequisite of all carpooling contracts. We present such a service in the context of Real-Time Carpooling service, and more generally in the context of demand responsive transportation system. The concepts of this push service were validated through experimental service at a stadium of French Ligue 1 of football during the past two years.
