Driverless metro in Milan rides on integrated surveillance and evacuation solution

Milan's new driverless metro line five which opened earlier this year has deployed an integrated security system that combines video surveillance with public address communication. Ansaldo STS designed the security system, which consists of 400 vandal resistant domes,10-bit digital processing technology, video and audio signal transmission encoders, as well as 10 iSCSI storage units. Ansaldo was supported by system integrator Tyco for this project. The Milan metro is the longest metro system in Italy, with a total length of 92 kilometers and 101 stations has a daily ridership of over one million people.

Due to the peculiarity of the city's ancient and magnificent architecture and the resultant constraints, lines of communication between the single security components needed to be as minimally invasive as possible. This was why the decision was made to install a wireless LAN network to cover the 13 kilometers of line, along with 19 new stations, where video cameras and a public address system needed to be integrated.

The main tasks of the surveillance and evacuation solution were to provide video monitoring and passenger movement control on trains and in stations. This included providing public information while guaranteeing increased passenger control and safety, as well as the management of any system alarms and diagnostics together with continuous event recording. All sub-systems operate independently, even in the event of a network failure or other outage, providing maximum operability and thus maximum security. Finally, all the systems supplied by Bosch were integrated via a SDK in the control room to form one complete solution.

This means that Milan's fully automated M5 line can be controlled by a single operations center, which processes all the information centrally. The center is able to issue all the necessary commands to ensure the correct functioning of the line, the safety of the passengers, timely maintenance measures, and the optimum use of operational personnel (mobile agents). As a result, the Italian city can rely on modern, LAN-based security technology for intelligent traffic control coupled with the highest standard of safety.
