DETECTION OF INCIDENTS IN TUNNELS

Automated detection and alert

Automated incident detection in transport tunnels is a vitally important safety initiative. Without automated incident detection, monitoring officers may be alerted to an incident only by use of an emergency telephone or a heat detector, minutes after the incident occurred. Fast incident detection and verification is crucial in preventing major tragedies in tunnels.

The Tunnel Incident Detection System
