Keep the Traffic Moving: Incident Detection, and the Rapid Response it Offers, is Vital in Modern Tunnels as is Equipment to Keep Them Clean and Smoke-Free

This article describes new technological advances in tunnel safety. The first is a system that creates an electrical field that acts as an electrostatic "roof" over a road segment. This allows fine particles (PM 10) to become electrically charged and collected for disposal. Another technology described is one that was used on a project along the Black Sea coast in Turkey, which includes 20 tunnels that are receiving an intelligent automatic detection system. It provides video detection of incidents and direct visual feedback. Once an incident is detected, the tunnel management system automatically activates operating plans. Variable message signs are also activated for drivers in the tunnel. From within the central control room, the operator can verify the details of the alarm and dispatch police resources or take other actions, including deploying message signs to divert traffic. The center will also manage lighting, ventilation, power distribution and supply, along with fire detection and fire fighting. Backup power systems and an independent network of seven control substations provide redundancy.
