North Yorkshire County Council electronically monitored traffic driving past Easingwold Community Primary School for the whole of the last week of February 2000:
Two thirds of all vehicles were exceeding the 30mph speed limit
More than a third of all drivers were travelling faster than 35mph
On average, six drivers every day were going faster than 70mph
In September 1999 the Department for Transport said of 20mph zones:
"Average speeds reduced by 9 mph, annual accident frequency fell by 60%, the overall reduction in child accidents was 67%, and there was an overall reduction in accidents to cyclists of 29%"
Department for Transport published research on speed tables (humps) in February 1996:
"Installing 75mm humps reduced speeds between the humps by an average of about 10mph."
Department for Transport published research on speed cushions in January 1998 showing they are all but ignored by most vehicles:
"55% of cars and 90% of buses were found to straddle the cushions"
Department for Transport on speed cushions in September 1999:
whilst speed cushions can reduce and control vehicle speeds, they do not match the effect of flat or round top road humps
In a survey of 4,600 Hull residents in areas where 20mph zones have been introduced:
72% though traffic had slowed down as a result
26% thought there was less traffic as a result of the scheme
48% thought the scheme had made the area a more pleasant place to live
71% would recommend traffic calming to someone in another area.
Government research shows:
at 40mph, 90% of people hit by vehicles die
at 30mph 20% die
at 20mph 2.5% die
