4G Camera Traffic Control


Background

A-one+ is responsible for maintenance on some of the busiest sections of trunk roads in England. Our Enhanced Network Control Centre (ENCC) aims to tackle delays and provide a better service for the travelling public when clearing congestion on the network and communicating delays.

Solution

Following a successful trial using cameras to monitor traffic flow during a major bridge refurbishment on the A1 Western Bypass, we made plans to set up a dedicated wireless camera network in the area, directly linked to the ENCC.

Our team designed and set up the network in partnership with specialist wireless CCTV, ensuring it was exactly right for our needs.

The system is monitored 24 hours a day. Operatives are not looking for moments of a collision itself but are instead looking for signs of tailbacks forming.

Using the cameras the cause of delay is quickly located and the right resources are deployed first time to deal with the incident and clear the delay as quickly as possible.

Thirty 4G cameras cover every metre with three cameras covering Tyne Tunnel approaches to monitor delays or incidents that might impact the area A-one+ are responsible for.

The wireless technology was necessary as there is no fibre cabling in the area to provide a network. Each camera takes an average of 20 minutes to install requiring only mobile lane closure and once in place requires little maintenance and provides uninterrupted coverage.

One problem was that the Western Bypass does not have constant, 24-hour supply of power; the lighting columns are only powered between dusk and dawn.

Our team developed a new type of battery power system, suitable for the size, weight and exposed location of the cameras, which charges overnight using the lighting column power supply and then provides consistent power throughout the day.

The new battery system has proved so successful that Wireless CCTV is now using it throughout their business.

On average there are 2,000 breakdowns per year on the Western Bypass and since the installation of the cameras, data shows that A-one+’s reaction time has improved by four minutes from the year before when there were no cameras.

The ENCC also has variable message signage located around the Western Bypass which is updated to advise motorists of delays, the reason, changes to speed limits and possible lane closures. This is linked to Highways England regional control centre so gantry signs can be updated to warn motorists in advance of the area affected.

Following the success of the 4G camera network around Newcastle we have purchased an additional 30 for use on schemes throughout the network area where there is potential for delays.
