Critical Dynamic Display System Upgraded to Enhance Control Room Efficiency


During 2015, Highways England expanded the capability of its Eastern Regional Control Centre at South Mimms. With their existing dynamic display system reaching its tenth year in operation, a superior replacement was required in order to cope with increased operational demand. The Eastern Control Centre has 20 operator positions, of which, four are designated for training and two, which are in a separate room are used during major incidents. Images can be selected from approximately 870 cameras.


Highways England required a videowall that would be brighter, of higher resolution and use less power than its predecessor. It was also essential that the system did not require consumables such as projection lamps that would need regular replacement. The control room had to remain operational throughout the installation period.


Electrosonic installed 24, Mitsubishi Electric 67” LED illuminated cubes with a 4:3 aspect ratio that matches the camera images exactly. The cube solution required only 127 watts per display, and features automatic colour balancing so that all cubes in the array give a uniform performance. A very narrow 1mm bezel between the screens offers virtually seamless images across the wall. An Eyevis videowall processor was chosen for its flexibility and capability of dealing with many source types. In order to ensure that performance targets are met, Electrosonic’s Service Department has a two year contract to provide regular maintenance and emergency cover for the dynamic display system.


The videowall can display a flawless combination of high resolution video and graphics, with any image appearing wherever required. Overall resolution, brightness and reliability has been improved, while reducing the need for maintenance, which has heightened the control room’s operational effectiveness.
