Current requirements for tunnel safety can be summarised in one sentence: having everything under control. Traffic managers want a system that allows them to stay in control of the situation, no matter what happens. As such, they are able to guarantee top-level safety and security for the road user.
With automatic incident detection all incidents inside each section of the tunnel are detected within a couple of seconds:
- Stopped vehicles
- Underspeed
- Traffic congestion
- Smoke
This allows operators to take all necessary actions to make sure any incident has a minimal chance to escalating. The situation remains under control.
However, for certain traffic specialists this is not enough. More and more traffic managers are convinced that they can bring safety to a higher level by implementing a redundant AID system. The Fréjus tunnel is a perfect example of the redundancy solution offered by Traficon.
WHAT IS THE REDUNDANCY FOR A TRAFICON AID SYSTEM?
“The ability of a system to keep functioning normally in the event of a component failure (e.g. power or network communication failure), by having backup components that perform duplicate functions. Redundant components can include both hardware – and software elements.”
The power of such a redundant system is that it prevents loosing important data and, last but not least, the operator knows he can count on the system 24/7. He remains in control of any situation.
