Reliable, Zero-Maintenance Detection for Demanding Tunnels

Tunnels present unique challenges for designers, operators, and maintenance teams who must ensure safety, uptime, and reliable operation under demanding conditions. With the right detection technology, vehicle monitoring becomes more than a requirement — it becomes a strategic tool to improve traffic flow, enhance safety, and deliver stronger operational performance

Non-intrusive detection

Fast, simple installation with no pavement cuts.

Built for durability

TDC3X-T is engineered for all tunnel regimes—from frequent high-pressure wash-downs to wall-only cleaning or minimal maintenance. IP66/67 ingress protection ensures consistent performance despite washing cycles and corrosive tunnel atmospheres.

Actionable insights

Real-time, consistent traffic data enable smarter traffic decisions — improving throughput, smoothing traffic-flow, and reducing or delaying stop-and-go conditions for better overall traffic management outcomes.
