Abstract: A car pooling transport management system (1) comprises a central server (2) having a bank of prediction servers (3) linked with a geographical model (4). Vehicle on-board units (OBUs, 6) have prediction clients (7) which communicate with the central server (2) via a mobile network (10). Each OBU (6) has a satellite locating system, in this case GPS-based, to track actual vehicle position. Each prediction client 7 develops a vehicle prediction model for the driver's regular routes and communicates data concerning the vehicle prediction model to a prediction server (3) running on the central server (2), and in a normal transport/commuting mode compares in real time the position and timing of the actual mute of the vehicle against a route of the vehicle prediction model and transmits progress updates to the prediction server (3). The prediction server 3 consolidates the data from the various prediction clients 7 and builds a geographical model 4 for all of the OBUs 6 of the system 1.
