How LiDAR Automation Protects Critical Infrastructure

Tunnels are among the most complex and valuable pieces of transportation infrastructure. Their safety depends not only on structural engineering but also on the advanced technologies that monitor traffic before vehicles even enter the tunnel. When that technology works correctly, it prevents accidents, protects assets, and keeps vehicles moving.

But even with strict rules in place, over?width commercial vehicles sometimes slip through, and the results can be costly. Damaged tunnel walls, destroyed signage, and downtime for repairs all impact safety and traffic flow. To address this recurring challenge, the Austrian motorway operator ASFINAG partnered with SPIE Dürr Austria and EBE Solutions to develop an automated width?monitoring system built around SICK LiDAR sensors.

Although the project originated in Europe, the problem – and the solution – apply directly to North American roadways where DOTs and agencies manage thousands of tunnels, bridges, and critical choke points every day.
