Last month, Eric Morris wrote a post on red light cameras at traffic intersections in L.A. that sparked a robust debate in the comments section, something we always like. The debate centered around whether these devices are effective at reducing people's willingness to run a red light, or whether they're merely sources of revenue for the city. Perhaps you'll feel similarly passionate about a new Australian study that examined the benefits of fixed speed cameras in New South Wales. From an ABC.net.au article:
On the whole [Auditor-General Peter Achterstraat] has found that speed cameras do change driver behavior and improve road safety but not in all cases. He has found 38 of the 141 fixed cameras across the state seem to have no significant benefit to road safety.
