And chp would be cleaning up alot of messes at on location all in the name of tickets it's not realy worth it. A significant feature of system control is interconnection that permits the metering rate at any ramp to be influenced by conditions at other locations. In this algorithm the number of vehicles that the signals allow off the ramp is calculated as the difference between the flow before the ramp and the pre-specified capacity of the road. Ramp metering has been implemented on Autobahns in several areas in Germany, including the Rhine-Ruhr area, Munich, and Hamburg.
