Nonsense, we are removing lots of 20mph restrictions on roads.
Glad to see that.There are many cases where it seems to me 30 wouldn't be any more dangerous.
In contrast to the assessment of the pdf's numbers given above, when I asked AI, on the way home, what the numbers were, what it presented was fairly convincingly a benefit in the reduced speeds.. I did have to ask for the numbers, some of the "trends" were misleading.
One I remember was a 75% reduction in children's deaths. Actual number was from 4, to 1. That's not statistically meaningful.
Some of the measures for "traffic calming" seem to be immature, ill targeted. Like the speed pillows that motorbikes can scream between. (I've done that, to a point.) Humps of unregulated dimensions, some of which break car springs - I've had that too.
They put bus stops out into the road so the traffic has to stop - and they see that as a great way to reduce car speeds.
Stopping traffic doesn't make it safe!
An interesting - to me - answer would be for orange cameras to go up, which impose small fines, with the profit going to the council, and no penalty points. The cameras would then be self - financing. At the moment, all fines go to hmg, councils being without the necessary authorities.
People wouldn't be so offended, I think.
Blanket 20mph seems very inefficient. I'd bet the accidents happen disproportionately in specific places.
Signage is bad too, how about say a GREEN central line where the limit is 20, so it's obvious?
