Minister, it's a fact that fewer than half of children walk or cycle to school. Research shows that the encouragement of active travel to school is hampered by issues related to the amount of traffic outside school gates. I've always supported 20 mph speed limits outside schools to help keep our children safe, but some councils in Wales have gone further, introducing 'school streets', where roads directly outside school gates are close to non-resident traffic during drop-off and pick-up times. This seems to me to be a sensible way of encouraging pupils to walk or cycle to school. So, what discussion have you had, Minister, with ministerial colleagues and others about encouraging local authorities all across Wales to adopt this approach to help keep our pupils safe and healthy going forward?
