This local traffic control system is supplemented by close circuit television (CCTV) cameras for the visual surveillance of intersections. Efficient interplay between the individual traffic signals and CCTV cameras, and smooth traffic flow are assured by a ‘dynamic free wave’ program. Every traffic signal installation receives the required coordinated switching commands. The result: less congestion and an efficient use of the existing infrastructure.

The SITRAFFIC Concert system provides traffic information to assist operators in making the right decisions and respond to traffic congestions. Further, a sophisticated Siemens power supply system provides back-up supply to ensure the road users are never left in the dark.
