The M30 tunnels are not just another tunnel-infrastructure project, but their special characteristics of the urban route and forecast traffic density make them a world-leading reference for traffic-management and safety in road tunnels, turning the control centre into the driving force that coordinates and synchronises installations and human resources.

There are two control centres: Main and Mobility. The functionality of the main control centre is control and safety in the Calle 30 tunnels, while the mobility centre will handle traffic management and control for the M30 and act as a backup for the main control centre. The project includes the construction of the building that will house the main control centre.

A powerful communications network will be set up, based on Gigabit Ethernet technology with redundant topology, to permit the interconnection of all tunnel installations with the control centres and other centres in Madrid.

The integration of systems within the ambit of this project involves:

• Design of software applications based on latest-generation platforms.
• Scalable relational databases.
• Mass data storage via high-speed networks and clustered servers for control and management.
• Integration of the operating manual into the application.
• Study and design of critical algorithms for the system: ventilation and fire.
• Redundant remote system.
• TCP/IP integration of video, audio and data systems.
• Integrated audio-communications system responsible for the centralised management of automatic telephone communications, SOS posts and TETRA and PRR (for operations and maintenance services) radio communications.
• Database-operation system based on reporting tool.
• Simulation and training server for tool operators and administrators.
• Web-based publication of useful information on tunnels and traffic.
• Full traffic studies to channel needs inside the tunnels.

Integration of subsystems necessary for the control of the tunnels:

• DAI.
• Fire-extinguishing (water-spray based).
• Automatic evacuation of emergency exits.
• Number-plate recognition.
• Interconnection with other control centres, data and video exchange to optimise tunnel operations: Traffic Department, Urban Tunnels.
• Interconnection with other organisations to coordinate emergency situations inside the tunnels: CISEM.
• Control of the system via authorisation mechanisms.
