Variable Message Signs 1

With a single sign that serves multiple functions, Variable Message Signs (VMS) are an ideal LED signage solution for influencing road user behaviour.
Coeval supply a complete range of motorway VMS, from single line to full colour matrix, and urban VMS with a wide range of pictograms and text messages.

Coeval is a specialist in robust, LED road sign-based systems that advise, inform, educate and protect.

Intelligent VMS can be used to support a number of measures from improved road safety to air quality monitoring; every 4 minutes, someone is injured on a British road and poor air quality is the biggest environmental threat to health in the UK with up to 36,000 deaths a year attributed to long-term exposure (Public Health England, March 2019).

There were 1,748 road deaths in the year ending June 2019, as reported by the DfT (30 July 2020). The statistics also show there were 153,315 casualties of all severities in reported road traffic collisions in 2019. This is 5% lower than in 2018 and is the lowest level since 1979.

The Environment Audit Committee has estimated that total health costs, due to air pollution, range between £8.5 billion and £20.2 billion a year. Utilising intelligent road signage to influence road user behaviour and increase the attractiveness of active travel (walking and cycling), by improving safety and comfort, can support road safety and the improvement in air quality.

Coeval’s VMS are modular in design and can be supplied in one, two or full colour, in varying sizes, and from 12mm to 25mm pixel pitch. We also supply a wide range of parking, tunnel and toll signage.

    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.’

    Platinum Electrical Ltd
