| Comment | Potentially - although that's much harder to track.
(There's a lot of argument around "regression to the mean": there are a couple of bad accidents on a stretch of road, a camera gets put in. No accidents happen for a while, is that because of the camera or because bad accidents are relatively rare and the first two were random events?)
When I studied some of this back in the late 90's, the cost of a fatal accident to the public purse was over £1 million. That will have gone up significantly since, probably higher than inflation.
At the time, the government had spent more money scraping bodies off the A77 between Glasgow and Kilmarnock, than the motorway cost to build.
(It was a particularly bad road - two lanes each way with no central reservation - so the same argument doesn't apply elsewhere, although the A9 would have a decent claim) |
