Monitoring of Cargo Transport in Urban Areas Using GPS/EGNOS Technologies as Part of the Safety System

Safety in the transport of goods in cities much depends on the choice of route and monitoring of heavy vehicles in urban areas. When a passage route has been selected, the transport firm must have control over the driver's performance. This article presents results of research into the accuracy of the position determination by the GPS/EGNOS system in highly urbanized areas with continuous building lines. The results are compared to those obtained in open field areas.
