combined level crossing flashing lights and traffic lights

[onestrangeday]

I have attached the photo for discussion and clarity.


I am wondering does the car drivers are more likely to obey the flashing lights or the traffic lights(personally, I think the driver would be more likely to obey the flashing light since it 'flashes' and attract the driver attention----in other words, flashing lights are more effective than the traffic lights) I'm not sure whether I am right for this ?
what might be the human factors behind this ? How could level corssing control desgin take theses issues into account ?

Beside, what are reasons for this kind of combined installation ???
I think wouldn't be better to install separatley !!

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.
