20mph limits & speed humps do not work - IAM on DfT data
Discussion
Association of British Drivers PR said:
Based on the latest accident figures published by the Department for Transport, and analysed by the IAM, those areas that have introduced 20-mph zones and speed humps have worse Killed and Seriously Injured (KSI) figures than those which have not.
Yet these measures remain in widespread use and seem to be appearing more frequently, 20mph limits are championed by those heavyweight libdims. Barnet seems to have other ideas at least as far as speed humps are concerned, removing them without ill effects it would seem.Discuss.

20mph Zones and Speed Humps Do Not Work
New Casualty Statistics Show Failing Policies of 20 Zones and Speed Humps
Based on the latest accident figures published by the Department for Transport and analysed by the IAM, those areas that have introduced 20-mph zones and speed humps have worse Killed and Seriously Injured (KSI) figures than those which have not. The IAM reports (see Note 1 below) that:
1. The biggest KSI increases between 2010 and 2011 were in St. Helens and Portsmouth. The latter had an increase of 57% whereas the national change was only plus 2% (probably due to weather factors). Portsmouth is one of the few cities that have introduced a 20-mph zone over the whole of the area, and subsequently claimed a positive accident improvement based on very limited data. This more recent information shows that the expenditure of over half a million pounds of taxpayers money on this scheme was a total waste of money and that those who promote the Portsmouth scheme as a success are seriously misleading the general public. The money should have been spent on other road safety measures that are known to be effective.
2. Are speed humps a good solution? No. The evidence from Islington and Camden in London, which are undoubtedly the boroughs with more speed humps than others, and have also used 20-mph schemes extensively enforced by humps, show that they also have the worst figures of KSIs per vehicle mile travelled.
The ABD continues to call for the use of effective road safety measures supported by sound scientific evidence, rather than simplistic attempts to reduce accidents by wasting money on speed reduction techniques.

It's all a waste of money in Oxford and if the greenies push on in Brighton & Hove it's doubtful BiB will have the resources to do much more.
