UK cities should have more 20mph speed zones, as they have cut road injuries by over 40% in London, a study claims.
In particular the number of children killed or seriously injured has been halved over the past 15 years, the British Medical Journal reported.
The London School of Hygiene and Tropical Medicine study estimates 20mph zones have the potential to prevent up to 700 casualties in London alone.
Well, I can't think of anyone more qualified to do a study on 20mph zones.
The researchers compared data on road collisions, injuries and deaths in London between 1986 and 2006, with speed limits on roads.
Is it a quiet time for tropical disease research, then?
After adjusting for a general reduction in road injuries in recent years, they found that the introduction of 20mph zones were associated with a 41.9% drop in casualties.
What kind of adjustment? Why is any kind of adjustment needed? Either 20mph zones make a difference or they don't. Or maybe they've been attending the CRU's classes on data fiddling?
He estimated that 20mph zones in London save 200 lives a year, but this could increase to 700 if plans to extend the zones were implemented.
Is this using the "adjusted" figures, perchance? And I rather think this figure is calculated using the same method as the amount of money lost to music piracy each year (as in it's completely made up, because they have no idea if people would have bought the music if they couldn't otherwise download it - in this case they can't firmly state 200 lives have been saved because they've don't conclusively know that they would have been lost if the 20mph limit wasn't there).
Kevin Clinton, head of road safety at the Royal Society for the Prevention of Accidents, said: "This research confirms that one of the most effective ways of protecting vulnerable road users, especially children, is the introduction of 20mph zones.
All very well. For the record, I think that 20mph zones in residential areas/around schools/high streets, etc are generally a good thing, provided we don't see "feature creep" of people then pushing for these limits in non-residential areas as well.
But I would ask: What the fuck has happened to this gentleman?
Surely, with the introduction of 20mph speed limits, education for pedestrians and cyclists should come with it? After all, leaving aside the extreme minority of cases where a car has mounted a pavement, if a pedestrian was hit in the road by a car, it's likely they weren't looking properly, a mistake which is exacerbated by a car travelling at excess speeds. Cars need to keep to the speed limit, but by the very same token, pedestrians need to be aware of how to look for traffic properly, and pick safe places to cross.
It's all very well having this plastered over every advert break:
But let's have a little balance, shall we?:
