Some models can determine the traffic direction on several lanes.
Over-height vehicles collide with bridges and tunnels frequently. Due to their low clearance height, older bridges are now considered at risk of vehicular strikes. A bridge or tunnel strike occurs when a vehicle, typically a lorry or a truck (even vehicle cranes or oversized loads), tries to pass under a bridge or tunnel lower than its height and subsequently collides with the structure.
Bridge and tunnel strikes are recurring events that cost thousands of euros in repairs, maintenance, and inspection. They create enormous damage and represent a real danger to road safety. For example, a vehicle stuck under a bridge affects traffic flow because it can close one or more lanes until it is removed.
Therefore, Comark has developed several Overheight Vehicle Detection Systems (OHVD) solutions that alert drivers to maximum height limits to avoid collisions with infrastructure.
Over-sized detection systems are significantly more cost-effective than repairing infrastructure and, most importantly, help prevent potential issues. They operate effortlessly: when the sensor detects that a vehicle is taller than the infrastructure, it sends an alarm to alert the driver to stop or take the nearest exit to avoid a collision with the obstacle. These sensors can detect vehicles traveling at both low and high speeds.
