The objective of SITRAFFIC Concert is to precisely record the inbound and outbound traffic in Athens and ensure that individual traffic is optimally guided through the city.
The integration of all trafficrelevant data and the optimum switching and control of all traffic signals and information media makes it possible to speed up traffic flow in Athens, resulting in less congestion and less pollution.
The complex task is supported by networked cameras, independent loop detector systems, video recording systems for expressways, and dynamic displays for congestion warnings and detour recommendations, for example.

The task of the traffic control system (TCS) is to provide a system-wide traffic overview and information basis that encompasses all traffic systems and enable quick and effective checks and interventions.
Since the existing traffic facilities such as the planning system, traffic computers and the parking guidance system were no longer up to meeting today’s high demands, they had to be upgraded or replaced by modern, networked systems.
The primary objective was to create an open system with standardized transmission technologies and interfaces (OCIT) to ensure full high-quality data communication capability across all subsystems.

The customer expected a “smooth transition” from the previously installed systems to the new, technologically innovative solution.
The new SITRAFFIC Central traffic control system would gradually take over the central monitoring and control of the traffic signal systems in Geneva and thus progressively replace the four outdated traffic computers and one operating computer.
In addition, it had to be guaranteed that the new system would offer at least the same range of functions for monitoring and controlling all traffic signal installations previously connected to one of the traffic computers.

In order to increase the performance of the Copenhagen traffic network, a traffic-actuated control system was to be introduced.
The system operates on two levels. First there is the macroscopic control, which is part of the traffic computer and considers the city center as a whole (including the interaction between the individual intersections).
Then there is the microscopic control, which works in the individual controllers and optimizes the signalization at each intersection.
