So below the federal recommendation and worse, not uniformly but more often on lights with cameras leading to non standard light behaviour. Because we really want unpredictable behaviour from our traffic system... that can only lead to safer roads... like variable length steps on a stair case.

These people should be charged with public endangerment.

edit: Also as someone pointed out, less warning to pedestrians to clear the cross walk and less time to do so. Very safety conscious.

After you turn 14 you'll realize there is actually never an appropriate moment for an Ayn Rand quote.

I have never read Ayn Rand, but I have heard of her before. Why are such quotes inappropriate?

They make some people's head 'splode, others generate kneejerk responses. For an otherwise obscure writer, that that she is so well known to have detractors everywhere is itself telling, but you'd have to judge for yourself what it is telling about.

I think short yellows are dangerous, especially with loaded vehicles. US DOT should set standards for minimum yellow light times. Here is one such proposal: http://www.shortyellowlights.com/standards/ EDIT: Linked to proposed standard and equation

They do, through the MUTCD: http://mutcd.fhwa.dot.gov/knowledge/faqs/faq_part4.htm#q32

There's an inherent conflict of interest when cities, counties, and states rely on traffic tickets as a source of revenue. The all-too-tempting incentive is to maximize that revenue, either by abusing civil rights or, in this case, by endangering public safety.

It won't necessarily endanger the public if they add more delay between one light turning red and the other turning green.

You're not responding coherently, but it's indeed a fact that delayed green lights create safer intersections.

Here's a news story from 35 years ago on the topic: http://news.google.com/newspapers?nid=1913&dat=19780310&...

he's pointing out the irony cops endangering traffic safety in supposed aim of improving traffic safety

Is there a reason to believe that the police are trying to improve _traffic_ safety at this place? Perhaps they are trying to prioritize _pedestrian_ safety. That is, after all, why most no-turn-on-red signs are installed in California.

Seems extremely unlikely that they suddenly realize they need to increase pedestrian safety at the end of each month. I've been working there for about a year and the pattern of never being there and then suddenly appearing at the end of the month is unmistakable.

I had previously thought such rigid quotas were mostly urban legend until I saw the pattern repeat over and over with my own eyes.

Huh, it's interesting that there's actually an engineering standard for yellow light times that local governments don't seem to acknowledge. I've always been annoyed at the dangerously short yellow lights around here (Denver), compared to the rest of the country. (I think they were short even before we had red light cameras.) When I'm traveling in other states, I often find myself automatically hitting the brakes when I see yellow, only to sit at the yellow light for a few seconds. :/

After you turn 30 you realize that not everyone will believe what you do or be right about everything, but when they are right about one thing and you disregard it 'out of principle', you look the fool.

After you're 50, you'll be wishing they gave you enough time to make it through a crosswalk before the lights change...

How goes giving someone less time to stop before someone else goes not decrease safety? Why not shorten the yellow time to zero?

There is a portion of time where all of the lights at the intersection are red. The person you are responding to notes that as long as this portion of time is increased such that the total time that the intersection has for someone to clear it (i.e. - time that the light is yellow plus time that the lights are all red) stays the same then safety inside the intersection should not be impacted. This says nothing about…

You make an excellent point.

I am worried about the case where the driver, distracted, looks away from the intersection for a second. Returning their gaze to the light, they see it red. They never observed it yellow, and thus they have no idea how long it has been red and whether or not it is safe to run the light. Perhaps this is why we have yellow to begin with--as an redundant means of clocking the time until the opposing light turns green.

An appropriate partial quote of Ayn Rand's Atlas Shrugged: “Did you really think we want those laws observed?" said Dr. Ferris. "We want them to be broken." "But just pass the kind of laws that can neither be observed nor enforced or objectively interpreted – and you create a nation of law-breakers – and then you cash in on guilt."

Why is HN so obsessed with Ayn Rand? It's a serious question that I've been meaning to ask for some time. I never heard about her before joining Hacker News, and since then it's been at least once a week. Is this a Silicon Valley thing?
