A lot of Dutch junctions have beg buttons. Or they look like beg buttons but might be motion sensitive. I've never quite figured it out. They also have little "Wacht" lights with an LED progress bar*, which I think are essential if you want people to use them properly.
(* Because Dutch junctions are heavily optimised and skip or shorten unnecessary cycles, they don't count down linearly so its easy to think you'll be waiting ages, get distracted and look up - usually prompted by a native sailing past - and see you have a green light)
The Advance Stop Line areas are an embarrassment of wonky thinking.
