TOLL TAGGING ON TRIAL AT DARTFORD

Two automatic vehicle identification (AVI) systems, introduced by Dartford River Crossing Ltd., are on trial at the Dartford Tunnel. The systems, one from Philips and the other from the American company Amtech, rely on a radio frequency transponder tag which is attached to the inside of a vehicle window. As the vehicle approaches the toll booth, the tag is interrogated by the system, and identified by means of a unique programmed code. This allows the motorist to continue without stopping and enables the system to debit a pre-paid account. The Philips system, Premid, offers a remote read and write facility (i.e., programming) while the vehicle is moving, and is simple to integrate into a complete computer controlled system with automatic customer billing if required. The Amtech device, which works by an individual personal 20 digit code plus other codes for security is backed up by its own specially designed computer software for billing, reporting and collecting tolls.
