Wireless vehicle detection system hits the roads

Capita Symonds has been working with Blackburn with Darwen Borough Council and Clearview Traffic on the implementation of the new Golden River M100 Wireless Vehicle Detection System.

The system, which allows more reliable and cost effective traffic detection, has been used to upgrade three of Blackburn’s major intersections.

The decision was taken to use a new innovative wireless technology, which is more reliable and provides cost benefits for the Council, instead of using the traditional ‘inductive loop’ based detection technology (normally seen as dark square outlines on the road surface).

The loop technology detects a passing vehicle by using a magnetic field to detect the metal components in the vehicle.  Whilst accurate in detection, loops are prone to a number of failures including road degradation, utilities and other works which can reduce their effectiveness and thus can contribute to congestion.

The Golden River M100 Wireless Vehicle Detection System - part of the Clearview Traffic Group - provides a more reliable, lower cost and easier to install alternative to the use of inductive loops. The system uses small independent magnetometer sensors in the road surface which wirelessly transmit real time data via secure radio technology to a nearby Access Point. This in turn feeds either locally-placed or remote traffic management controllers to ensure optimum traffic flow.

The system has a quick and simple installation process at around 15-20 minutes per sensor. It is also cheaper to install than loops and involves minimal traffic disruption. Once installed the M100 provides a ten year maintenance free period and is far less susceptible to damage than traditional loops.

The system is providing significant cost benefits to Blackburn with Darwen Council. Ian Richardson, Capita Symonds' Director said: “By implementing the M100 wireless vehicle detection system at three major sites we have reduced installation costs by around £60,000 and will continue to create efficiency savings through reduced replacement and maintenance costs”. 

Councillor Alan Cottam, executive member for regeneration and environment, Blackburn with Darwen Council welcomed the innovative technology, saying:

Keeping traffic flowing is important for businesses, commuters and air quality. This is cost effective technology which is easy to install and reliable and provides a real benefit to motorists
