In the past, vehicle navigation systems have been confined to high-security loads or the larger distribution fleets, partly because of their high cost. However, prices have recently dropped so dramatically that such systems are now more affordable. The growing involvement of lorry manufacturers is a sign that the market for these systems is expanding. Volvo claims that its Dynafleet system can increase vehicle utilisation by 5-15%. Foden's Fodex is based on a well-established Australian fleet communications system. The Mercedes-Benz contract-hire operation, Charterway, is using real-time tracking of vehicles and mileage in its new On-Line contract hire package being launched in April 1999. The most common form of vehicle navigation takes latitude and longitude readings from a global positioning satellite (GPS). Some tracking systems are hybrids, where a GPS satellite does the positioning, but the position is then relayed to base using a variety of terrestrial communication systems. All systems allow data on vehicle performance and load status to be downloaded remotely; this can lead to a crucial reduction in operating costs. Hybrid tracking systems have contributed to much lower vehicle communication costs. Monitoring events for vehicles on the road enables schedule adjustment to allow for traffic delays and re-routing.
