We've had a few of them in Belgium, but they've fallen in disuse due to lack of maintenance etc.
They didn't always give a correct speed to catch the wave either.
Should be a lot easier with todays electronics and sensors.
In the north of Belgium, we're down to a measly 4 gov't employees synchronizing lights, while the administration puts up more traffic lights that these folks synchronize per year ... suffice to say, there's hardly any road at all where the lights are synchronized.
