I've seen a number of places when driving where there are warning
signs about pedestrians; since mapping I notice more things when
driving and usually this corresponds with a footpath crossing the
dual carriageway (I'm thinking A120/A12/A14 which is a route I've
driven quite a bit). Usually the bit where they are to cross is
evidenced by the crash barriers between the carriageways suddenly
being two barriers with a gap between them, so effectively there is
a footpath between the two barriers.

I'd be tempted just to draw the ways on, stick maxspeed tags on the
A3, and hope that whichever routing engine you have in mind can put
a penalty on paths that cross roads with high maxspeeds and no light
controlled crossing on the node(s).
