Each time a high sided vehicle approaches infrastructure that runs over the road it is travelling on, there are serious potential consequences for the driver,
others in the vicinity and the infrastructure in question.

We have technology solutions to help prevent incidents associated with ‘overheight vehicles’ and protect both the infrastructure and the user.

Coeval’s vehicle warning sign systems use sensors to constantly monitor traffic flow on approaches to the infrastructure, such as a gantry or bridge. This means it can identify an overheight vehicle in advance of it reaching the infrastructure that they are too high to pass through.

When an overheight vehicle is detected an intelligent LED sign illuminates, instructing the driver to take the nominated diversion, stop or turn back.

With this simple measure, Coeval’s OVD System directly addresses the issue of drivers not knowing the height of their vehicle. As well as the clear benefits of their responsive nature, the warning signs are robust, vandal resistant and visible in all conditions – an especially crucial benefit in the winter, where driver visibility can be a challenge.

The road sign technology is fully customisable, so the message is bespoke to its location, providing specific instructions to the driver. The LED signage can be accessed locally or remotely when using our Cloud Control Solution.

These warning signs have been shown to reduce bridge strikes wherever they have been implemented.

Bridges
Bridge strikes are costly to both rail and road network operators; creating hours of delay and disruption for all involved and risking the lives of anyone directly or indirectly involved.

An average of five bridge strikes occur every day – potentially endangering lives every time – despite the current risk reduction initiatives. At best, there is no negative impact on human life, but each strike causes infrastructure damage resulting in disruption to both rail and road users.

In simple monetary terms, bridge strikes cost on average £13,000 per strike. Historically this equated to around £23m a year of UK taxpayers’ money. These figures relate to the costs associated with the bridge assets. In addition, we have both the financial cost to the wider transport network and the impact on the environment, caused by road traffic delays and congestion associated with a bridge strike.

The physical infrastructure around the bridge location plays an important part in advising, informing, and enabling HGV and bus drivers to avoid low bridges, with more effective warning road signage and improved turning areas, for example.

Tunnels
The same applies to tunnels where drivers of high-sided vehicles need to be informed and made aware of the height of the infrastructure and to turn around / divert if their vehicle is too high.

Ports
We have been working in a highway environment for over 30 years and are now applying our technology solutions to other environments, including ports. Our OVD technology is one solution, designed to warn HGVs of port infrastructure where their vehicle is too high to pass through and redirect them safely.

The port environment can be difficult to work within, operating 24 hours a day, in all conditions, with multiple employers and contractors carrying out different activities. Add to this the operation of workplace transport in close proximity to pedestrian workers and there is an increased risk of accidents.

With many different people driving around ports and not all of them being familiar with the environment, accidents involving transport occur every year, resulting in people being seriously or fatally injured.

    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

    ‘Having used Coeval for the first time, we found them to be friendly and really helpful in ensuring we received the correct item we required. We were happy with the extremely quick response times and professional service they offer. We would definitely recommend their services to others.’

    Gloucestershire Airport

    ‘Thank you for your prompt and efficient service regarding our request for training on the 21st of August. You guys have been incredibly helpful over this.’

    City of Edinburgh Council

    ‘Coeval won the tender for the replacement overheight vehicle detector systems. The work was completed within programme and budget. We are now satisfied that the new systems will help protect the bridges for several years to come.’

    Swindon Borough Council

    ‘A sound, honest and efficient service provided by Coeval. Would be very happy for Coeval to manufacture and supply more of Swindon’s signs.’
