What is often forgotten that a red light and a flashing red light have very different legal meanings to a driver (road in this case). A steady red can be passed under certain circumstances, i.e. emergency services. Flashing red prohibits anyone from passing it under any circumstance!
There are many installations in the UK where rail signalling and road traffic control are cut into each other. Look at most metros with on street sections. I believe it is NET that actually has a length pass through the centre of a large roundabout! As for wig-wags and traffic lights on the same post, I seem to remember one at North Pole for a non-public road crossing at a very acute angle to the railway.
