Data Display can provide customised signs for a variety of tunnel applications. For example LED displays at the entrance or approach to the tunnel can inform drivers or vehicles of speed restrictions and lane closures. Data Display electronic tunnel signs are also excellent for safety messages, lane control and general commuter guidance on the approach to a tunnel. Tunnel displays can also be used in conjunction with Automatic Number Plate Recognition (ANPR) and speed detection devices.
A wide range of LED tunnel displays are in use at Eurotunnel on the UK and French side and also at Limerick Tunnel in Ireland.
