Tunnel Britz, Berlin Tempelhof / Neukölln
Improving the traffic control system
Inner-city motorway tunnel (1,7km) on the Berlin city ring (A 100) - It features lane control signals, traffic guidance systems, barriers, height-detection, variable message signs and a sub-center.
The tunnel Britz has been released for traffic in 2001. The commissioning of the connecting sections of two urban motorways (A 100 and A 113) has led to a significant increase of the traffic volume. The altered traffic situation in the south-east Berlin city ring required an optimization of the tunnel's traffic control system.
Located on 20 different measuring points, the existing ceilung-mounted radar detectors are able to determine the number of vehicles passing (cars/trucks), their velocity and the lanes' capacities, as well as the road's weather condition. The data is captured every 15 seconds and is then transferred to the traffic computer. It will then automatically perform the necessary traffic control actions, such as:
- Harmonization of traffic flow
- Congestion warning
- Signalin potential risk of congestion
- Reduction of the maximum speed limit
- Signaling of wet lanes
- Signaling of fog
VIA Beratende Ingenieure services included:
- Analysis and preparation of the data
- Evaluation of the rules and algorithms featured in the automatic control system
- Suggestions for the adaption of parameters and software adjustments
- Optimization of the control parameters
- After system installation: Evaluation of the changes over a period of 3 months
