Hampshire County Council have reported that there is no road safety benefit from signed-only 20-MPH speed limits. The county have installed such limits in 14 residential areas since 2012. But this is what Stuart Jarvis of the Council said: “In terms of accident and injury data, the impact of the pilot schemes upon road safety is projected to be neutral and there is no evidence of enhanced road safety benefits compared with that observed for the entire road network maintained by the county council”. The overall accident rates for the pilot schemes have actually risen, although this is not considered to be statistically significant. There have been marginal, or nil, reduction in traffic speeds in the scheme areas.
The residents in the scheme areas seemed happy though so it is not proposed to remove the existing 20-mph limits. But it is unlikely that any new such schemes will be installed.
The full council report on the schemes is here:
Comment: The ABD has consistently argued that such schemes cannot be justified on any sensible cost/benefit basis and that the large amounts of money spent on them would be much better spent on other road safety programmes. Not surprisingly perhaps, the latest Hampshire report does not mention the costs and links on the council’s web site to previous reports and decisions that might have mentioned the costs seem to no longer work. I wonder why that is?
It is regrettable that Transport for London (TfL), and local borough councils such as Croydon, have consistently ignored the mounting evidence that wide-area signed-only 20-mph schemes are a waste of money. TfL continue to finance them with taxpayers’ cash, and local borough councils in London are still implementing them. Why do they continue to ignore the evidence?
