There is a story in the Telegraph that claims that there have been fewer accidents since Swindon turned off their speed cameras last year. tinyurl.com/282gadn .
Of course, this being the British Press, there is not the slightest indication of whether the change is statistically significant. I have no idea, but the numbers look similar enough to me that I strongly suspect that the actual story is 'Turning off speed cameras makes no difference at all to accidents'. Which frankly is not much of a surprise, but nice to know.
