Coeval | The Overheight Vehicle Detection system

Coeval are pleased to introduce THE OVERHEIGHT VEHICLE DETECTOR SYSTEM.  This market leading system has been devised to assist the prevention of overheight vehicles colliding with low obstacles e.g. railway bridges, tunnels, viaducts, aqua-ducts, motorway junction networks and flyovers etc. 

The Overheight Detector constantly monitors traffic flow approaching low obstacles.  When an overheight vehicle is detected a sign illuminates instructing the driver to DIVERT, STOP or TURN BACK.  Mounted on poles approximately 100 metres from the obstacle, the warning provides sufficient time for the driver to take action to avoid collision as instructed.  This system not only protects the low obstacle but also other road users and members of the public.  Prevention of collision avoids costly repairs to the obstacle and the delays and inconvenience associated with such works.

This system emits two beams of infra-red light from a pole on one side of the road to two detectors mounted on the opposite side of the road.  The beams of light are set to the warning height for the obstacle.  They detect overheight vehicles passing through the beams and trigger the system to illuminate the warning sign.  The system is direction sensitive ensuring that overheight vehicles moving away from the obstacle do not trigger a warning. 

This system offers advanced technology, sensible optical design, uncomplicated electronics and is vandal resistant.  For those requiring additional control, remote monitoring and traffic camera triggering facilities are available.  As no two road layouts are the same the system is designed to be flexible and is pre-set at the time of installation. 

SUCCESS OF THE OVERHEIGHT VEHICLE DETECTOR SYSTEM

Documented evidence suggests the use of THE OVERHEIGHT VEHICLE DETECTOR SYSTEM reduces the number of overheight vehicle accidents by at least 80%.  Other than removing the obstacle, the system is regarded as the most effective signing measure available.

RECENT PROJECTS

Coeval Ltd has recently had the pleasure of providing OVERHEIGHT VEHICLE DETECTOR SYSTEMS and support for the following projects:

Dartford – 26 systems for the new Dartford River Crossing

The City of Edinburgh Council – 15 systems for their Overheight Vehicle Detector Replacement Scheme

WEB BASED OVERHEIGHT VEHILCE DETECTOR REMOTE MONITORING UNIT 

The Coeval web based OVD Remote Monitoring Unit provides an online time-stamped log of OVD sign activations.  Information is accessible via a password protected web page on a Coeval managed server where the data is stored.

All Remote Monitoring Unit operation and emailing options can be configured by the end user.  Log file emails are sent to the end user either daily, weekly or monthly.  The preferred choice is configured on the web based customer control panel. 

Sign activation can be used to power a relay or similar to:

Trigger an image camera

or

Activate a video camera for a predetermined period of time

The Coeval Remote Monitoring Unit must be located in a GPRS coverage area and uses a standard data SIM card to connect to the server.  The unit can be attached to the Overheight Vehicle Detector System, providing statistical data and the option of photographic or video evidence.  The Remote Monitoring Unit enables effective incident monitoring and response.
