Comprehensive tunnel renovation: monitoring, control, and safety systems in a tunnel where 30 million vehicles pass through each year
In colaboration with Aldesa, Acisa successfully carried out the project “Upgrade of the tunnels between km 17+500 and km 55+000 on the M-50 motorway” in order to meet the minimum safety requirements according to the Directive 2004/54/CE and RD 635/2006″.
The project has optimised the tunnel road safety by modernising the Perales del Rio tunnel in the Getafe region used by an average of 80,000 vehicles every day. Located at kilometre point (kp) 39+650 on the M-50 motorway, it has a length of 690 metres, two independent tunnels (one for each direction of traffic), and four 3.5 m lanes in each tunnel.
Our project consisted of renovating and updating the tunnel’s safety and control systems to comply with the Royal Decree 635/2006, aimed at reinforcing overall safety and optimising traffic flow conditions. To achieve this, we renovated vertical and emergency signs, communication systems, gas detection equipment, electrical systems, lighting systems, and fire protection systems.
We also improved the emergency exits from the inside and outside, installed fire doors, implemented an overpressure ventilation system to prevent smoke from entering the tunnel, if there is a fire and installed regular lighting and evacuation guide lighting.
All the systems were integrated into SEITT’s R4 Control Centre in Pinto using Sagit Tunnel platform, our road tunnel control solution, which seamlessly integrates all infrastructure systems: safety, ITS, ventilation, lighting and electricity based on high standards of cybersecurity and system availability.
