\nSpeed contributes to causing accidents and it also increases their severity.
\nA pedestrian hit by a car at 40 mph has a 95% chance of being killed, at 30 mph this becomes 50% and at 20 mph it becomes 5%.
\nMost child pedestrian road deaths would be averted if people drove at 20mph in side streets. As few places are more than a mile from a main road, few journeys involve more than two miles on side roads (a mile at each end). The difference between driving two miles at 20mph and at 40mph is 3 minutes.
\nWe are killing our children to save less than three minutes on our journeys.
\nIn residential side roads 20 is plenty.
\nTo enforce this policy we need
\n \u2022 A 20mph speed limit in residential side streets
\n \u2022 A recognition that motorists are solely responsible for the injuries that occur in accidents in residential side streets to the extent that they exceed those that might have been expected at 20mph. The concept of contributory negligence by pedestrians should apply only to injuries that would have been likely to have occurred anyway at 20mph. Any excess over that should be the motorist\u2019s fault.
\n \u2022 Ideally we need to reshape streets so that they are used primarily for community use and the vehicle is a guest.
\n
\n.
\nThe Dutch concept of the \u201cWoonerf\u201d (living street) (often called Home Zones in the UK, although the Woonerf is more radical than many Home Zones) divides up the street for community use. Car parking spaces are provided, usually in nose to kerb car parking places so that the parked cars add to the obstacles to traffic. Space is allocated to gardens, trees, communal meeting space and play areas. The carriageway becomes simply the gap between obstacles and is usually arranged in chicanes to slow traffic down.
\nThis concept has other advantages as well as slowing traffic down. It increases community networking and social support (the Appleyard & LIntell study in San Francisco, recently replicated in the UK, has shown that people know more of their neighbours in lightly-trafficked streets). It improves environments. It creates usable greenspace. It increases the aesthetic attractiveness of the street so as to encourage walking.
