OVER-HOverheight Vehicle Detection System
Detects Overheight Vehicles Before They Reach Road Infrastructure
OVER-H is an Overheight Vehicle Detection System that checks vehicle height using a laser sensor on road sections with clearance limits, automatically reads the license plates of vehicles exceeding the defined limit, and warns the driver through a Variable Message Sign.
It monitors vehicles approaching tunnels, underpasses, bridges, enclosed parking entrances, and similar areas with height restrictions; when a vehicle exceeds the limit, it generates an alarm, identifies the license plate and vehicle type, and transfers the warning to the relevant VMS display.
Overheight Vehicle Detection System
OVER-H is an electronic control system that automatically verifies whether vehicles comply with a defined height limit and generates a driver warning for vehicles exceeding the limit. While the laser sensor checks vehicle height, the license plate recognition system identifies the vehicle’s license plate and type.
The Integration Module combines information from these two sources within the same incident record and enables the warning to be displayed on the VMS. The vehicle’s license plate is shown on the VMS together with a message directing the driver to the control point, helping prevent damage to road infrastructure.

Frequently Asked Questions
What does OVER-H do? +
It checks vehicle height using a laser sensor on roads with clearance limits, reads the license plate of an overheight vehicle, and warns the driver through a Variable Message Sign.
How is an overheight violation detected? +
The laser sensor measures vehicle height and compares it with the clearance limit defined in the system. An alarm is generated if the limit is exceeded.
Does it read the vehicle’s license plate automatically? +
Yes. The license plate recognition system automatically detects the license plates of vehicles passing the control point.
Can the vehicle type be identified? +
Yes. In addition to license plate information, the license plate recognition system can transmit vehicle type information to the Integration Module.
How are the laser sensor and license plate information matched? +
Information from the laser sensor and license plate recognition system is combined in the Integration Module, and the overheight alarm is matched with the correct vehicle and license plate record.
How is the driver informed? +
The violating vehicle’s license plate and the relevant warning message are displayed on the Variable Message Sign.
Which information can be displayed on the VMS? +
The vehicle’s license plate, information that the height limit has been exceeded, an instruction to stop, or directions to the control point can be displayed.
Is OVER-H a penalty system? +
Its primary function is to detect vehicles exceeding the clearance limit and warn drivers before they reach the road structure. Use of records in other administrative processes depends on the project scope.
Can different clearance limits be defined for different roads? +
Yes. The monitored height value can be defined according to the clearance limit of the road or structure where the system is installed.
Which road structures can it protect? +
It can be used for tunnels, underpasses, bridges, enclosed parking entrances, and other structures with height restrictions.
Can it direct the driver to an alternative route? +
Where suitable road and VMS infrastructure is available, the driver can be shown directions to a control point or alternative route.
What are its main components? +
It consists of a laser sensor, license plate recognition system, Integration Module, and Variable Message Sign.
