Schneier on Security: Red Light Cameras Don't Work

advertisement

Interesting: the solution to one problem causes another.

"The rigorous studies clearly show red-light cameras don't work," said lead author Barbara Langland-Orban, professor and chair of health policy and management at the USF College of Public Health. "Instead, they increase crashes and injuries as drivers attempt to abruptly stop at camera intersections."

Who's leading the conversation?
This visualization below allows you to see the impact that each user has on the current conversation. The top row contains the group of users who have had the most impact, the 2nd row the group of users who have had the 2nd most impact (et cetera). Users with similar impact are grouped together, and the average score of the group is shown to the left of the group. The author of the article is also shown on the left, in their corresponding group. Each user's score is based on the number of comments the user has made plus the number of votes their comments have received. The scores are calculated relative one another, so while their absolute value is not particularly important, their relative difference does indicate a larger difference in impact on the conversation.

As I mentioned in my comment on the blog entry, three cameras would work: the first two measure your deceleration -- you get fined for excessive deceleration, as measured by covering the first two speed cameras in too short a duration; the third camera fines you if you cross it.

Insurance companies won't be too happy, but speed camera manufacturers would. The city, not sure: it depends on how many people get caught for slamming on the brakes.

A nice thing about multi-camera systems is that you can vary the fines: if you cross a red light but traffic in the perpendicular direction is non-existent, you should get fined less. If you suddenly stop because someone cut a red light, you should not get fined. But that might be too rational.
