And which is why if you have a close look on Google Earth (
clicky) you can make out the solid white lines across the road which indicate where to stop when the red flashing lights (also just about visible on the road edge) that warn of an approaching aircraft are lit (even easier to see on Street View....the lights and warning signs that is, not the approaching aircraft!). Of course there are moron's who believe these lights are advisory....
I stand corrected.
It does seem like an odd set-up though having no physical barrier beyond some painted lines on the road and a set of traffic lights (if only for the safety of the pilot - never mind the numpty who decides to run the light in his HGV)
