The need for a visible message is not always fixed or permanent, sometimes people need to be informed of temporary roadworks, flood warning, changes in traffic flow or upcoming events in the area, and more recently we have seen mobile displays used to communicate Covid-19 messages.

With a single sign that serves multiple functions, Mobile Variable Message Signs (VMS) are an ideal road signage solution for informing, advising and influencing road users and the wider public.

Coeval supplies a complete range of Mobile VMS, from single line to full Colour Matrix, Vehicle Activated Signs (VAS), and Urban VMS with a wide range of pictograms and text messages.
This means our signs can be used for a wide range of customer requirements from road safety/warning signs to event management.

Coeval’s solar powered Mobile VMS are easily deployed and simple to programme, making them a perfect solution for providing temporary and effective messaging.
Our Mobile VMS range includes full-size and compact (see Portable VMS) options and offers LED signs that are modular in design and can be supplied in one, two or full colour, in varying shapes and sizes, and from 12mm to 25mm pixel pitch.

This trailer VMS solution combines full colour matrix VMS with a simple moveable trailer whilst retaining the benefits of our fixed VMS; including remote monitoring and control, multiple communications interfaces and data logging and download functionality. The full colour matrix display provides excellent resolution for messaging that is clear and legible.

They can be easily transported and positioned safely whilst also being robust, to ensure they remain in place with no risk of theft. In addition, all trailers can be fitted with battery monitoring and GPS tracking for theft and removal detection. Displays can be updated remotely using a Coeval’s web-based interface and mobile 4G coverage which is accessible from any device from any location.

Low power consumption, easy to use and fully trackable – Mobile VMS are the ideal solution for effectively displaying
temporary information in a range of situations/environments.

    What our clients say

    Connect Plus Services M25 Dartford Crossing

    ‘Even a short closure of the tunnel causes great congestion in the area, and if an over height vehicle were to cause that level of damage, the tunnel could be closed for hours, if not days, which would bring the whole of the South East of England to a standstill.

    When the Coeval over height vehicle detectors were first installed, we were talking about 10’s of vehicles a day that we were stopping; we are now down to low single figures, 4 or 5 vehicles a day we need to extract for being over height, so it’s a great improvement in efficiency through the crossing.’
