In recent years, traffic flows have changed significantly as a result of socio-demographic developments and changes in the network structure in northern Thuringia. This led to the necessity of a fundamental revision of the 15-year-old coordination of traffic lights in the course of the B 247. The aim was to reduce the environmental impact by liquidation of traffic. The study was based on a comprehensive empirical assessment of traffic demand in 15 junctions.

In a second step, all traffic light programs were adapted and the existing synchronised traffic Lights, the so called "Green Wave", optimized. The entire traffic flow was tested with the help of a traffic-dependent microscopic traffic flow simulation, on the basis of which the reduction of negative environmental effects could also be demonstrated.
