| 摘要： | The Welsh Parliament voted in favour of 20mph becoming the default urban speed limit in July 2020 and the subsequent order came into effect, only about six months behind schedule, on 17 September. The Restricted Roads (20 mph Speed Limit] (Wales) Order 2022 was brought in under the Road Traffic Regulation Act 1984, which allows for speed limits to be changed on restricted roads - where lampposts are no more than 200 yards apart. Welsh local authorities were asked to consider which roads should remain at 30mph and follow the statutory process on traffic regulation orders (TROs] to make the exceptions. The risk of being killed is almost five times higher in collisions between a car and a pedestrian at 31 mph compared to the same type of collisions at 18.6mph - 'at the point a 20mph car would have stopped, a 30mph car would still be doing 24mph' - the Welsh Government's 20mph Task Force Group reports. In Wales, the official estimate is that average speeds on the affected roads will fall from 22.2mph to 19.5mph, which is consistent with a reduction in free flow speed from 31 mph to 26mph. This may seem a small change, but the 20mph task force highlights that: 'Research by the Transport Research Laboratory has shown that for urban roads with low average speeds there is an average 6% reduction in collisions with each 1 mph reduction in average speeds.' |
