Electronic surveillance in Stockholm 20 Dec 2018

18km of the new bypass is underground

Communications, control and monitoring technologies are to be supplied to the underground Stockholm bypass highway by Siemens Mobility. Some 18km of the new 21km bypass is aligned underground in twin three-lane tunnel excavated mostly by drill+blast through hard rock.

The €75 million contract awarded to Siemens by Swedish Transport Administration, Trafikverket, is for a comprehensive system to control safety functions throughout the tunnels, as well as a communications platform, camera surveillance, radio and mobile telephone network and fire and incident detection systems.

“With digitalization, Siemens Mobility will make this infrastructure intelligent, increase value over the entire life cycle of the installation and enhance the experience of all using the bypass,” said Michael Peter, CEO of Siemens Mobility.

Siemens Mobility is to co-operate with Eltel Networks Infranet on the project. Prior to installation, Siemens will provide a design for the monitoring and communications systems. Eltel will assist in the design and delivery of the system and will execute installation work in the area. Siemens Mobility will operate and provide maintenance throughout the system together with Eltel. Testing of the installed technologies is to begin in 2021.

As a separately managed company of Siemens AG, Siemens Mobility had a revenue of €8.8 billion in fiscal year 2018 and had about 28,400 employees worldwide.
