Updates from SIEMENS


Monitoring and controlling tunnel traffic
SIEMENS – One of Siemens’ first tunnel projects was the 15-kilometer Arlberg tunnel in Tyrol some 30 years ago. Since then, Siemens has equipped so many tunnels in the world that, placed end to end, they would extend around 500 kilometers. The company also played a key role on one of Europe’s largest tunnel projects, the Bolaman-Persembe highway. The 28-kilometer four-lane road between the towns of Bolaman and Persembe, which includes 40 bridges and five tunnels with a total length of 4,600 meters, is an important connecting roadway on the Black Sea. Siemens technology ensures the efficient and safe operation of the five tunnels, one of which, the Nefise-Akcelik tunnel, is the longest in Turkey at 3,800 m. The 350-kilometer four-lane road along the Black Sea coast from Espiye to Sarp on the border with Georgia encompasses a main control center and seven control substations for a total of 29 tunnels, as well as the required technical infrastructure, including traffic management, fire protection.

A smoothly functioning road, rail, and mass transit network is decisive for the economic wellbeing of regions and states. Tunnels play an important role in these. They enable people to travel to their places of work and they connect companies with their suppliers and markets. They ensure that locations are easy to access so that they remain attractive to industries and investors and competitive. For cities, tunnels are an effective means of facilitating economic activities that depend on transportation while reducing the traffic burden in inner cities. more> http://tinyurl.com/njfm35p
