Dynamic Route Information: Beacons or Radio

Two technologies which are emerging to lead the field in driver information systems are the Radio Data System Traffic Message Channel (RDS-TMC) and the infrared beacon-based route guidance system ALI-SCOUT. While both systems offer attractions over current technologies such as ARI, these approaches are not truly integrated at this time.
RDS-TMC primarily provides traffic information to drivers concerning events such as accidents, severe weather or congestion. ALI-SCOUT provides routing advice, but no background information on the traffic conditions which determine the best routes. The systems also differ in that ALI-SCOUT is only supported in areas equipped with beacons, while RDS-TMC can potentially cover wide areas; and in that ALI-SCOUT provides feedback on actual travel speeds, while RDS-TMC relies on external data sources.
This presentation builds upon current work carried out within the European Communities' DRIVE RDS-ALERT project, which aims toward the standardization of RDS-TMC throughout Europe. It includes some results of recent work carried out for the Rijkswaterstaat, on Dynamic Route Guidance Systems. It also outlines further work now required covering systems integration and field trials in the DRIVE II program.
