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).
