Dr Rod Tolley from the UK spoke of the resurgence of walking worldwide. A lecturer from Griffith University talked of town planning here to answer much of what Dr Tolley had recommended.
Housing developments on the grid plan lend themselves to walking to the shops, to school etc., whereas modern suburbs seem to favour lots of cul-de-sacs not linked to each other. This precludes the easy running to time of local buses and is impossible for emergency vehicle access.
We need walker-friendly suburbs!
