M62 traffic management system for Highways England.

A Digifort VMS system has been used by Graham Firth Communications Ltd. on the M62 motorway for traffic management. The Digifort VMS controls over seventy Redvision X-SERIES™ rugged PTZ dome cameras. The M62 is one of the busiest motorways in the UK and the traffic management system, which operates between junction 9 and 12, regularly views up to 120,000 cars a day.

Graham Firth Communications Ltd is a security integrator specialising in the design, installation, maintenance, and management of temporary CCTV systems for Highways England. The company is involved in many major motorway improvement and maintenance projects across the UK, often with 24/7, remote monitoring included.

Highways England is a government-owned company which operates, maintains and improves England’s motorways and A roads. It is responsible for traffic management CCTV systems and on-road signage, as well as providing real-time, web-based, traffic information to traffic officers and the public on its Traffic England website. The prime purpose of the new CCTV system is to manage signage and vehicle speeds to avoid congestion. However, Highways England is also accountable for all incidents on its road network, so is constantly reviewing ways to improve road safety, including through its systems, products and processes.

Paul Scott, technical director at Digifort UK, said, “The traffic management system comprises seventy Redvision RV30, X-SERIES rugged PTZ dome cameras. These were supplied to Graham Firth Communications through our distributor, Videcon Ltd. A Digifort, open-platform, Video Management System, which runs on high-resilience, DELL servers, is used for recording and control. Digifort’s free client software is installed on DELL PCs in the system control room where there is a video wall comprising sixteen monitors configured in multi-screen, alarm screen and report screen modes. There is also a dedicated, fibre network infrastructure, with a massive bandwidth and low latency, to ensure the X-SERIES™ cameras are accurate and responsive for operators over the large distances involved. Digifort UK helped Videcon and Graham Firth Communications with the project design, specification and commissioning, as well as with ongoing UK support.

“The Digifort VMS system used in the project was selected for its intuitive, logical and easy to use front end. It allows the camera channels to be individually configured for each operator in the monitoring station. Video Analytics is used to trigger alarms if there is a stopped vehicle (SVD – stopped vehicle detection) ‘bookmarking’ the video timeline for subsequent, efficient searching and retrieval of video and sending real-time video alerts to operators. This helps operators identify and respond to incidents in real-time, such as when there is traffic congestion, accident or stopped vehicle.

“Digifort has no annual maintenance fees, so has no on-going overheads. More analytics can be added in future for further system intelligence; these include functionality like tailgating, vehicle counting, presence, enter/exit, appear/disappear, direction filter, speed filter, stationery, loitering, abandoned object and removed object. Further add-on modules include License Plate Recognition (LPR); Facial Recognition; Edge Recording; and Edge Analytics. This means there are no limits to the system’s upgrade flexibility.”

The RV30, X-SERIES™ rugged PTZ dome cameras, used throughout the system, are manufactured in the UK by Redvision. They are finished with marine-grade plating and a tough, powder-coated paint. They are IP67 weather-proof rated, as well as shock and vandal resistant and come with a wiper to remove dirt, grit, salt and rain from their optical, glass, camera windows. This makes them the ideal cameras for the tough, outdoor surveillance requirements of motorways.

The X-SERIES™ cameras are also easy to install, upgrade, replace, repair and service, with a Mean Time Before Failure (MTBF) rating of 7 years. This makes costly, unplanned, on-site failures unlikely. Redvision also offers a back-to-base repair service should any cameras go wrong.

The combination of the Digifort VMS and analytics software; Redvision rugged PTZ cameras; and expertise from Graham Firth Communications has provided Highways England with a robust and reliable motorway solution. This combination of products is being used in many other motorway applications in the UK.
