Wireless traffic management

2057 Golden River Traffic, part of the 557 Clearview Traffic Group, has unveiled the M100, a new road traffic data collection system that uses secure radio technology as a more reliable, lower cost and easier to install alternative to the use of inductive loops. It can be used for count and classify or for traffic light control and is suitable for all Urban Traffic Control (UTC) systems. Golden River says it offers a likely cost saving across 10 years of installation of as much as 46 per cent.

Granted full 1841 UK Highways Agency TR2512A homologation in February 2009, the M100 system uses magnetometer sensors flush-mounted in the road surface, removing the need to close a section of road to install the system and its associated wiring. The sensors wirelessly transmit real-time data via secure radio technology to a nearby access point, which in turn feeds either locally placed or remote traffic management controllers to ensure optimum traffic flow at a junction.

As well as being significantly less time-consuming and cheaper to install, Golden River says its wireless vehicle detection system has many other advantages over traditional inductive loops. Its small size and lack of wires allows it to be positioned in the middle of a lane, making the data it generates highly accurate. The system can also be easily fitted to existing sites to conveniently replace failed inductive loops.
