Development of an improved ERP system using GPS and AI techniques

This paper proposes a map matching and development platform created for a workable second generation electronic road pricing (ERP) system using Global Positioning System (GPS) and artificial intelligence (AI) techniques. Such a system will be well positioned to replace the existing gantry-based system used in Singapore due to its ease of reconfiguration of changing schemes. Search algorithms have been developed to intelligently map the raw GPS data points to the road network. Good accuracy has been achieved by performing point-to-segment mapping. The software developed, named ERP2, is designed to run on the Windows CE platform (for small devices such as PDAs), and has shown to produce good results in field tests. The system developed may potentially be extended to many other ITS applications such as calculating road tax and parking charges.
