Situational Awareness for Tunnel Operators

Monitor traffic flow and automatic incident detection alerts using Navtech's situational awareness interface.

Situational awareness

What is situational awareness?

Navtech’s situational awareness is a user interface for tunnel operators and emergency services.

Tunnel operators use the interface to monitor traffic flow and automatic incident detection alerts. When there is a serious incident, the same interface is used by emergency services to see the real-time location of vehicles and pedestrians in the tunnel.

ITS SOLUTION Why use radar technology in a tunnel?

Radar works when you need it most: in harsh tunnel environments and in smoke and hot gases, when other technologies start to fail.

Radar works in harsh tunnel environments, even when covered in dust and dirt. It delivers uninterrupted performance in smoke and hot gases. Cameras rely on light in the environment for detection and can’t see through thick smoke. At high temperatures, such as in a tunnel fire, the performance of thermal cameras is also impaired, while radar continues to work.

Single login to monitor all schemes

From just one login, the operator can monitor all road and tunnel schemes where our radar-based ITS system is installed.

Web-based UI

The interface can be viewed on a web-browser. It can be used by tunnel operators to monitor traffic flow and alerts, and by emergency services when responding to an incident.

Operator-friendly map-view

A map view helps operators quickly understand where an incident has taken place.

Speed and density heat maps

Traffic speed and density information can can be used to inform decision-making. Empty tunnel alerts can also be used ahead of scheduled tunnel maintenance.


Navtech’s Intelligent Transport System (ITS) will find a stopped vehicle or wrong-way driver in seconds so operators can get assistance to road users faster. The same system can provide further actionable data such as vehicle count and classification.
