The local council says that fewer road collisions are happening in Brighton & Hove streets where 20mph limits have been introduced, and the majority of residents consulted about extending the limits support the idea.
The council has monitored collisions and casualties from Phase 1 of 20mph limits in central Brighton & Hove, introduced in April 2013.
The figures show a 17% reduction in collisions and 12% reduction in casualties, compared with the average of the preceeding three-year period.
Prior to the introduction of 20mph the annual average in the three-year period 2010-2013 was 318 collisions, whereas under 20mph this fell to 264 collisions.
With regard to casualties the previous annual average was 371, but with the introduction of a 20mph speed limit this dropped to 327. There has also been a 20% reduction in serious casualties, down from an average of 53 to 43. On average, there has been one person a year killed on the roads in the Phase 1 area, but since the introduction of 20mph there have been no road deaths.
Councillor Pete West said: “We’re getting increasing support on 20mph from residents who feel it makes, or will make, their streets safer, more pleasant places to live.
“This is for the simple reason that you or your children are far more likely to survive being hit by a car at 20mph than you are at 30mph. Now, we also have the figures from Phase 1 showing it makes streets safer.
“Interestingly, support was highest in areas with pre-existing 20mph limits. That shows residents are seeing first-hand the positive impacts lower speeds can bring for safety and quality of life.”
NOTE TO CONTRIBUTORS
News stories about 20mph limits tend to produce lengthy discussion threads, but often these comprise multiple posts by a small number of contributors. To counter this, we are encouraging contributors to state their views once and then allow others to do the same – and then let the readers make up their own minds about the story. We welcome open debate and views from all quarters, but would like to avoid discussion threads, particularly on 20mph stories, becoming a dialogue between a small number of contributors – which can become repetitive and a little tedious for other readers. Thanks for your co-operation on this point.
