Data that shows 20mph does work

Well, when I say ‘near’, they meant up to 500 metres from schools. Using this measurement they gave the impression we had more casualties near schools than almost anywhere else.

It’s an odd measurement – I’m guessing most of the city is within 500 metres of a school. Some people said this was proof 20mph speed limits don’t work. The trouble is, the statistics were mostly from before we started rolling out 20mph limits.

In reality, data from phase 1 of 20mph limits in the city shows clearly they do work, with collisions down 17 per cent, overall injuries down 12 per cent and serious injuries down 19 per cent, with no fatalities.

The insurance company said we have a high rate of cycling accidents compared to most places. So some people suggested that means cycle lanes don’t work. But again much of the research data is from years before the big new cycle lanes in Lewes Road and Old Shoreham Road were open. Also, we have a lot more cyclists than many places.

The insurance company also said they counted these accident rates per head of population. So they ignored the fact we have about 11 million visitors a year, many of whom unfortunately will have accidents. People would naturally conclude that if roads near schools are dangerous, their children will be in danger going to school. You would never guess that general casualty figures are down, from 1110 in 2010 to 908 in 2013. Child pedestrian casualties are down 40 per cent since 2011. Serious child casualties more than halved from 12 in 2010 to five in 2013. That’s still too many and we’re still working hard on it, with more 20mph limits and a schools road safety programme.

With insurance companies, it’s always wise to get a second quote.
