Yeah, I've seen similar traffic lights at the entrance of some small Portugese villages to slow down the traffic. And that was last century. '98, if I remember well.
There even was no intersection or pedestrian crossing. The light just went red when a car was approaching and if you weren't speeding, it was on green right on time to let you pass without stopping or even slowing down.
Should I add that once he knew the system, our driver didn't mind to slow down anymore and since he often was speeding crossed a few red ones also?;)
