TRANSPORT MANAGEMENT SYSTEM
First Claim
1. A transport management system comprising:
- a plurality of on-board units each for installation in a vehicle free to travel on different routes, and comprising a wireless transceiver;
a server;
wherein each on-board unit comprises a prediction client adapted to;
monitor vehicle actual position,use monitored vehicle actual positions to generate a vehicle prediction model of routes frequently travelled by its associated vehicle,transmit data concerning the vehicle prediction model to the server, andtransmit vehicle progress data updates to the server as the associated vehicle travels on a routewherein the server is adapted to;
receive said data concerning the vehicle prediction model from each prediction client and use it to generate and maintain a geographical prediction model, anduse the geographical prediction model to generate predictions of each vehicle position, so that only infrequent vehicle progress updates are required from the prediction clients.

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. Using the geographical model (4), the prediction server (3) can continue to provide predictions of the vehicle'"'"'s progress, such that passenger requests can be processed without using the costly communication resource. Only when the prediction client (7) decides that vehicle progress has materially deviated from its predicted route, by comparing actual progress from say GPS with the local client prediction, does it communicate with the server 3.
