OVERHEIGHT VEHICLE DETECTION
Reduce the number of bridge and tunnel strikes immediately


Ask for registration to TOPAS2515C, this ensures the sign message is monitored, and faults raised if any of the sign message starts to fail.
Collisions or strikes caused by overheight vehicles can not only be extremely costly, but they can also cause significant damage to critical infrastructure and threaten both driver and pedestrian safety. But crucially, they can be avoided.
SWARCO’s TOPAS2515C-certified Overheight Vehicle Detection (OVD) systems are the ideal solution, utilising intelligent detection technologies to seamlessly determine whether a vehicle is too tall to safely pass under a bridge, tunnel or height-restricted area and provide guidance on the appropriate action to take.
The OVD system, which can be used with multiple interfaces including SWARCOs own MyCity system, or UTMC systems when using an OMU, simply activates a TSRGD-compliant fixed message on an LED display advising drivers to ‘Turn back’, ‘Divert right’ or ‘Divert left’ as appropriate, while there is also the option to create a bespoke and fully customisable design.
Live information from the SWARCO OVD system, including all activations and status, can be monitored and recorded through SWARCO’s intelligent remote management system MyCity to ensure safety critical signs are always in optimum condition.

Enhanced Road Safety / Proven Reliability / Live Data and Remote Monitoring
Key benefits of SWARCO's OVD system:
- Full internal monitoring as required by the latest TOPAS2515C standard:
- OVD Low Beam Fail, Single Beam Fail, Total Beam Fail, Presence Detector Fail, Amber Lantern Fail, Non Critical LED fail, Critical LED fail, Power Fail, Watchdog Fail, Sign Controller Fail, Luminance Failure
- Reduce the number of bridge strikes and reduce congestion
- Enhanced safety for all travellers
- Applications include bridges, tunnels, site infrastructure and car parks
- All activations and operational status monitored and recorded, also available remotely
- Also available in full colour VMS to display any message or graphic required
- Vehicle detection in carriageway to prevent spurious activations
- High speed radio link from detection to activate signs, no need for expensive ducting and cabling
- Option for system to be fully solar powered, combined with the radio activation above, the whole system would require no cabling or ducting.
