SAG – Your reliable partner for projects of any size.
Faults on traffic light systems often lead to congestion. In order to be able to react quickly in the case of failure, central monitoring is required. SAG had the right solution for the provincial road agency in Brandenburg.
SAG installed the web-based control and traffic counting system versasweb to monitor around 80 traffic light systems in the cities of Potsdam, Frankfurt (Oder) and Eberswalde. Using a web interface, users can view system faults at any time and immediately adjust settings. When a fault occurs, the SAG service teams are immediately notified by SMS so that they can resolve the problem quickly on-site. SAG equipped all monitored systems with routers so that the traffic light systems can communicate with the central traffic computer.
Besides monitoring, versasweb assists the provincial road agency by logging systems functionality. All operations such as shutdowns and downtime are logged in a type of diary. The data are stored and can be accessed at any time. In addition, traffic counts can be realised with versasweb.
