This is a difficult problem - I can't think of any way to tell (from 
existing data) whether a road is safe to cross without an explicit 
pedestrian crossing.  You can't just go on whether it is primary, 
secondary, etc - there are quite a few secondary roads which can be 
crossed without any trouble but there are also a lot where you wouldn't 
dream of crossing them (or indeed, can't cross them because there is a 
fence on the central reservation).
