Plenty of statistics to support 20mph speed limits

Duncan Barkes claims in his recent comment piece, ‘I sign petitions or form a view based on hard evidence’.

Good for him! Except he then writes an anti-20 mph article which is conspicuously lacking in any evidence, relying solely on the claims of a single pro-motoring lobbying organisation – the RAC!

So here is some evidence from the 20’s Plenty campaign to help people make up their own minds about 20mph speed limits on residential streets:

1 More people are killed or seriously injured walking and cycling in Worthing than any other town in West Sussex and about a quarter of those killed and injured on Worthing’s roads are children and teenagers – data from West Sussex County Council.

2 More than 95 per cent of the collisions involving Worthing’s children happen in areas not covered by school safety zones – data on collision locations from West Sussex County Council.

3 Research by Royal Holloway University of London has demonstrated that ‘schoolchildren cannot accurately judge the speed of vehicles travelling faster than 20 mph.’

4 If you hit a child at 30mph you are seven times more likely to kill them than at 20mph. If you hit someone over 60 years old, the risk is ten times higher – data from the Department for Transport.

5 In London, 20mph zones have been found to be associated with a 42 per cent reduction in road casualties over a 20-year period, including taking into account underlying trends – report by London School of Hygiene and Tropical Medicine.

Duncan got one fact right in his article, though – the 20’s Plenty campaign is definitely not just about road safety.

It is about improving quality of life for everyone in Worthing, helping people to feel confident in choosing to walk or cycle, reducing congestion and pollution, reducing traffic noise and generally making Worthing an even better place to live.

The campaign has received letters of support from schools, businesses, charities and other organisations and now has more than 1,200 signatures on the petition.
