What is NDGPS?
The Nationwide Differential Global Positioning System (NDGPS) is hoped to make traveling safer and to reduce the problem of road congestion. NDGPS is a radio navigation system implemented by the US Department of Transport. It is used in conjunction with global positioning systems (GPS) already in use to provide a more accurate picture of travel conditions. Recent reports have shown that almost 40,000 Americans die in auto crashes every year. Eighteen thousand of these deaths are due to single vehicle crashes. It is hoped that the use of NDGPS can greatly reduce these fatalities. NDGPS can tell drivers when they are leaving the roadway and exactly where they are in terms of the highway infrastructure. By using this system, drivers can be informed in advance of congestion hotspots and potential and actual crash sites. Consequently, drivers will be able to navigate their journey with greater accuracy and safety. Drivers will also be able to save time by avoiding congested areas. GPS will
