Maintenance, vehicle breakdown and calamities. As a road maintenance authority you can’t avoid them. In the event of blocked road sections or tunnels on motorways, safety, traffic control and the quick access of emergency services demand your full attention. You can’t afford to waste even a minute of time. With the CADO®, designed by SPIE, a calamity passage in a guide-rail can be set up anywhere to provide rapid access for emergency services such as the police, fire department and ambulances. Indeed, opening up the barrier provides a motorway traffic redirection solution in case road sections or tunnels are blocked. A CADO calamity passage can be used to create an opening in the central reservation so that it is easy for emergency services – police, fire and ambulance personnel – to move through motorway congestion or to make a U-turn on the highway. On this way they can get to the scene quickly. Speedy access means saving time and this time could mean the difference between life and death. The gate in the motorway barrier also facilitates traffic flow to resume following an incident or roadworks. It allows road users to make a U-turn and reverse their direction of travel. The CADO looks like, and has the same construction as a standard reservation barrier. When closed, the reserve barrier is continuous and the CADO is just as impact resistant as a fixed reservation barrier. The CADO opens to allow an entry up to 15 meters. This is more than sufficient to give emergency services speedy access. The CADO can be operated electro-mechanically or hydraulically and is activated either directly by an on-site control box or remotely from a central traffic control centre. Consequently, the need for internal and external personnel is low. Even more important is that this solution is much safer than a manual system since no physical power of a human being needs to be involved at the scene. Thus, no workers will be on the road. However, in the event of a powercut the CADO can also be opened and closed manually.
