I'm surprised!

Where I live you're safe from the red light camera if your front-two tires are over the white line when the light changes to red. Sounds like in Oregon you're only safe if you're out of the intersection when it turns red, which seems entirely absurd, especially for tourists / newcomers to the area. How am I supposed to know how quickly your yellow light changes on this street?

Re:Traffic lights worldwide set to change after a Swedish en... by kevin_b_er on Monday October 21, 2019 @11:41AM (#21313535)
You are not supposed to know.

You are supposed to be an income source for American Traffic Solutions, Redflex Traffic Systems, and the city in question. It isn't about safety anymore. It is about money.

Cities are known across the country to make yellow timing extra short to increase the money. https://www.motorists.org/blog/6-cities-that-were-caught-sho...

I'm sorry. I don't think I understand this comment. Can you clarify?
Re:Traffic lights worldwide set to change after a Swedish en... by inetknght on Tuesday October 22, 2019 @10:43AM (#21324142)
Sure. Let's consider a company that claims to reinvest in itself and ends up with a lower tax liability as a result. Every big company does this, but I'll admit that I like to pick on Amazon and Wal-Mart.

I think being able to reinvest profits into your own company is a great thing to be able to do. But I don't believe it's ethical to pay people little in order to reinvest in your own company and certainly not without the input of the workers affected. When Amazon's own workers are unable to do the very same thing -- reinvesting their own profits into themselves -- then Amazon's workers are certainly fleeced by a private corporation along the way.

Low wages are just the starting point here; any member of a community which is receiving less than a living wage also needs support from the community. Sometimes that support comes from friends and family or churches. Often it comes directly from your tax money.

I'm not saying it's a bad thing to send my tax money to help people though. I'm absolutely saying that I shouldn't have to. Large corporations reap millions and billions from their own employees. Why, exactly, is it fair that they should profit at the expense of the actual real humans doing their work?

Thank you for taking the time to reply. I appreciate it.

I think I understand what you are saying, but let me make sure. Are you saying you think corporate tax should be funding people in need and not personal tax (whether it property, sales, income, etc.)? To be honest, in my original comment I didn't really think about where the tax should come from, but I think I do agree with you. I do think something like a universal income could allow corporations more freedom as they'd be freed from the burden of feeding, clothing, housing, and healing an entire nation.

Re:Traffic lights worldwide set to change after a Swedish en... by inetknght on Wednesday October 23, 2019 @10:32AM (#21334996)
Why should the tax source be distinct? In my state of Texas, for example, there is no personal income; there is sales tax but that's more for corporate accounting than personal accounting. That leaves corporate taxes (and unreliably, fines) to pay for the state's budget. So then companies which engage in practices to minimize their tax risk avoid paying even that.

While I think a universal income is a laudable goal, I do not think our economy is automated enough to support it.

You don't think corporations should share the burden of feeding, clothing, housing, and healing the nation in which it reaps its profits?

I see. I live in an heavy income tax state, so I think that is why my mind went there initially.

Oh I do, I just don't want those things connected to employment. I am not comfortable with the current coupling of health care and employment, but corporations paying adequate taxes to fund these services offered to all I'm all for.

Thanks for the reasonable conversation, by the way. This thread has helped me learned more and think about different viewpoints on this topic.

The implicit premise of such arguments is that every WalMart (etc.) worker receiving benefits; would be employed at a party disqualifying them from public benefits if not for their present employer.

This is quite implausible, of course, which is why it's never explicitly argued, but the entire criticism falls apart without that assumption.

I've always found it to be an odd displacement of responsibility. If somebody doesn't have the resources they need to live, it's our collective ethical responsibility to provide a resource floor. Walmart et al don't magically gain ethical responsibility for providing this floor just because they purchase someone's labor, in the same way that buying a dresser from someone off of Craigslist doesn't make you responsible for making the seller has enough income overall. It's difficult for me to see this view as anything but a desperate ploy to abdicate direct responsibility for taking care of the neediest and foist it off on some perceived other

Most employers of relatively unskilled labor pay poverty wages because they can get the labor they are seeking at that price, and they haven't identified ways to get sufficiently better returns paying more to justify higher pay.

> and what can one of the biggest (or biggest) private employers in America do about it?

Why should they?

I'd rather just tax capital earnings as income, tax high-end income more, and fund a UBI than expect employers to act irrationally as public benefit agencies.

Their misdeeds are totally tangential to whether or not a city does the upstanding thing (raises taxes with approval or tightens its belt if it can't get approval) or the unethical thing (extracting more money from residents and people who pass through in the form of fees for services and fines for petty violations of civil law).

The most damning evidence for your perspective is how the cameras are basically hidden, painted black, made inconspicuous.

If red light cameras were about safety, the addition of warning signs "Red Light Camera Intersection" ahead of the lights would drastically reduce the amount of dangerous behavior.

That isn't how the incentives work, though. Instead they hide them, throwing away the powerful deterrent they've created, in an attempt to make money from the unwary.

Re:Traffic lights worldwide set to change after a Swedish en... by jonshariat on Monday October 21, 2019 @05:27PM (#21317611)
Playing devils advocate here: I think the reasoning behind it could be argued that if people dont know which intersections have red light cameras, they are more likely to not run reds at any intersection just in case. Similar to the idea behind [Panopticon](https://en.wikipedia.org/wiki/Panopticon). If the cameras were clearly labeled people might run reds in unlabeled intersections.
Re:Traffic lights worldwide set to change after a Swedish en... by kayfox on Monday October 21, 2019 @05:02PM (#21317322)
To clarify, the one the guy in the article is complaining about is not hidden, has been there for something like 15 years, and has plenty of signage warning about it.

It was also an intersection that had tons of accidents from people running the light before the camera was installed.

Re:Traffic lights worldwide set to change after a Swedish en... by olyjohn on Monday October 21, 2019 @05:46PM (#21317813)
You wanna know what reduces red-light related accidents more than cameras? Increasing the duration of the yellow light.

https://saferstreetsla.org/679/case-studies-longer-yellow-li...

Also increasing yellow light duration is significantly cheaper than contracting out a network of cameras to a vendor who takes over half the revenue from each ticket.

It's cheaper for society, yes. It's much more expensive if you're the government notionally "paying" for that contract. It's paid out of revenues you didn't have before.

As a potential counterargument, if you fear Red Light Cameras but don't know where they are, you'll drive more safely at all intersections, not just the ones where they're actually installed.
Re:Traffic lights worldwide set to change after a Swedish en... by gowld on Monday October 21, 2019 @06:26PM (#21318208)
That requires evidence that people drive more safely in their ticket-avoidance driving, vs accelerating through greens to beat the yellow, or slamming brakes on yellow to cause rear-end collisions.

The idea is to stop people running red lights everywhere, not just at red light locations.

If you run red lights, you should be banned from driving just like if you speed. The roads are unsafe enough as it is.

Punishing people for the light turning red when their back tires haven’t fully made it out of the box has nothing to do with safety.

If it was about safety, it would only hit people when the crossing traffic light turned green.

Re:Traffic lights worldwide set to change after a Swedish en... by jnty on Monday October 21, 2019 @08:32AM (#21311503)
Yes this is bizarre - it's the same in the UK, where crossing the stop line on red is the offence. Often in cities traffic will continue through the amber light so you often have to turn on red to clear the junction. (Pedestrian lights are generally timed to account for this.)

What if an obstruction appears in the road - a pedestrian or a u-turning car? Are you just meant to plow into them?

I'm guessing you're supposed to get the robot-generated penalty, get your court date, take the day off of work, and plead your blindingly-obvious case to the court.

..... /or/ they could change to make the offense fire if you enter the intersection illegally instead of exit "illegally". :-\

Re:Traffic lights worldwide set to change after a Swedish en... by pintxo on Monday October 21, 2019 @09:06AM (#21311798)
Interesting rule.

In Germany there is a 1 second grace period after the light switches to red. And apparently, even if your tires crossed the stop line after the 1st second, you will not get a ticket if the photo series shows you did not move across the intersection.

Urban rumors are that some taxi drivers used this to empty the (physical) film rolls on the cameras by slowly rolling forward and back across the line past the 1 second rule. I guess this does not work so well with digital storage.

> And apparently, even if your tires crossed the stop line after the 1st second, you will not get a ticket if the photo series shows you did not move across the intersection.

Indeed. For many years, there was a nasty traffic light in the Stuttgart city center (at the Main Station) which was guarded by a traffic camera. It was positioned inside a very sharp turn, and it was very difficult to notice that the light was changing to red if you were already on a position of the road which was too close to the intersection to see the large overhead traffic lights, but too far away to see the small traffic light at the side of the road. I remember my father sometimes only coming to a stop a meter past the traffic light, which always triggered the camera. It never resulted in a ticket, though, as he was standing and not moving.

Re:Traffic lights worldwide set to change after a Swedish en... by close04 on Monday October 21, 2019 @09:46AM (#21312158)
The reason is also that when the camera captures such an event an actual person gets to look at it and take the final decision, instead of just acting like a robot and dispatching the fine. They will use common sense to decide whether it was a punishable offense.

This is also the reason why it's never a good idea to flip off the camera. A court decided that looking at pictures of people showing the finger would have an emotional impact on the person analyzing them later so the fine in this case is much greater.

I live in Beaverton, OR. I'm not a fan of red light cameras but it's not that easy to get a red light ticket. We only have 4 intersections that have red light cameras[0], and they were put in because of the egregious abuse of the intersections. To get a red light ticket you would've had to either ignore or respond to a yellow light way later than anyone would agree is acceptable. There are intersections here where 3 or 4 cars will continue to turn on a red signal - it's insane.

Mr. Jarlstrom's wife may have been an outlier for the hardware and software that calculates the tickets. But, overall, the system is catching folks who are breaking the law.

Reducing the accidents (injuries and damages) is better than catching more people.

(Ignore this: clearly my memory is flawed. Indiana doesn’t actually say anything about yellow lights, either about the requirement to be out before it turns red or stopping safely if possible.)

Here in Indiana you’re supposed to stop on yellow if you can safely.

That’s hard to judge for law enforcement but an easy rule for drivers to follow, if they would in fact do so. Doesn’t matter then how long the yellow light is.

Re:Traffic lights worldwide set to change after a Swedish en... by balls187 on Monday October 21, 2019 @05:45PM (#21317807)
According to Title 9, that's not entirely accurate.

https://codes.findlaw.com/in/title-9-motor-vehicles/in-code-...

A yellow light only indicates that the light is changing to red, and that the right of way is ending (as marked by a red light). There is nothing that states what a driver must/supposed-to do when facing a yellow light.

Assuming a driver is obeying all other traffic laws, a driver is lawfully allowed to enter an intersection on a yellow light, regardless of whether they have the time to stop or not.

In most (all?) US jurisdictions, drivers are taught that if the light is yellow, you should stop if you can do so safely.

Re:Traffic lights worldwide set to change after a Swedish en... by shkkmo on Monday October 21, 2019 @07:08PM (#21318585)
In many US jurisdictions, including Oregon, you MUST stop for a yellow light if you can do so safely. Cops can and will ticket you for entering a yellow light when they deem that you could have safely stopped. I first learned this when one of my friends ticketed for this in Portland.

Since it difficult to remember which in which jurisdictions this applies, I always make sure to stop for yellow if I can do so safely.

Indiana has some silly law about signaling 200ft before a turn on rural roads rather than the normal 100ft. The local cops around IN highway 55 camp out, dinging people for this because the state highway signs are hard to distinguish from a 55MPH speed limit sign at that distance. Never mind if there's nobody else there to see you make your ridiculously unsafe turn.

I didn’t know that, and in fact it’s worse: 300’ if you’re in a zone with a limit of at least 50mph.

Re:Traffic lights worldwide set to change after a Swedish en... by fredophile on Monday October 21, 2019 @06:05PM (#21317986)
Seems reasonable to me.

50 mph is 264000 feet per hour. This converts to 73.3 feet per second. 300' means you need to signal about four seconds before turning or changing lanes.

Re:Traffic lights worldwide set to change after a Swedish en... by 1123581321 on Monday October 21, 2019 @06:45PM (#21318393)
Before turning, the time would be more like 8 seconds due to the need to slow down. It’s too long to be reasonable. And too much pressure to strictly adhere to the law would create perverse incentives to temporarily drop below 50MPH before signaling and to keep the signal constantly on in case one wants to pass a car. It’s better to have a reasonable law that’s easy to follow to foster a culture of high compliance rates.
Re:Traffic lights worldwide set to change after a Swedish en... by creato on Tuesday October 22, 2019 @01:27AM (#21320607)
Maybe the point is to be signaling before you start slowing down? It doesn't sound unreasonable to me at all.

When I turn off of rural highways with 50+ mph speed limits, I signal about the same time I let off the gas to start slowing for the turn. Braking is at least a few seconds later, turning is well after that.

Re:Traffic lights worldwide set to change after a Swedish en... by 1123581321 on Tuesday October 22, 2019 @02:39AM (#21320919)
It does sound reasonable if most people know where their turn is, start planning for their turn far in advance and take some time to coast before starting to brake. That’s probably what the group who wrote the law was thinking. It is not how people actually drive and it’s too far in excess of what following traffic needs to exercise caution or slow down.

One of the challenges of traffic planning is that people will do what feels comfortable and is working; it’s not really worth writing laws to force them out of that unless there’s an oil crisis or a municipal revenue crisis.

Re:Traffic lights worldwide set to change after a Swedish en... by macintux on Monday October 21, 2019 @08:01PM (#21318959)
I have three primary objections, but otherwise you’re right, it’s not unreasonable.

First, signage is generally awful in Indiana. I often don’t know that I’m turning 300’ in advance.

Second, I’d prefer a rule that’s simpler to follow but still (I think) achieves the same effect for those sharing the road: start signaling at least one second before you decelerate.

Third, treating this as a money-making operation for the police is perverse.

Re:Traffic lights worldwide set to change after a Swedish en... by kevin_thibedeau on Monday October 21, 2019 @08:27PM (#21319119)
MUTCD says this:

> In rural areas, the Junction assembly should be installed at least 400 feet in advance of the intersection. In rural areas, the minimum distance between a Junction assembly and either a Destination sign or an Advance Route Turn assembly should be 200 feet.

INDOT conveniently doesn't comply with this paragraph. You often only get a sign at the intersection itself with no advance. You're left guessing where the intersection actually is and when to slow down and signal.

You're in good company with the flawed memory. I went to Purdue out-of-state and a native Hoosier told me that you had to clear the intersection before it was red. Everyone else in the vehicle backed him up on it too.

This not being the rule where I was from (Virginia), I stopped by the DMV and picked up the handbook to see what else might be different, only to find that the rule was essentially the same as in Virginia (must enter intersection before it turns red).

It’s funny the kinds of falsehoods that people collectively believe. In CA, I can think of two widespread false beliefs about traffic law from when I was younger (no idea if they are still widespread). One is that it is illegal to drive barefoot. Another is that it is illegal to change lanes in an intersection. That latter one I actually got pulled over for but when the officer went to write the ticket I guess they couldn’t find the vehicle code section for it (because it didn’t exist).

It's not explicitly illegal to change lanes in an intersection but it is often unsafe.

It's not always possible to stop safely for a yellow light, especially if one is close to the intersection. Yellow lights should last long enough for a typical vehicle traveling at the speed limit and within some distance of the intersection to proceed into the intersection and make a complete (legal) turn.

That's exactly the idea behind the revised formula. (Which is an evolution of an earlier, similar formula that only considered the time to proceed straight through.)

When you drive in a new state, it’s good to look up whether the state is “permissive yellow” (e.g. California and Washington) vs “restrictive yellow” (e.g. Oregon) as well as whether it allows “right turn on red”.

A "restrictive yellow" light would be paired nicely with a speed trap, to increase revenue, since people will be monetarily motivated to "floor it" to avoid fees.

Wait, "right turn on red" is a state-by-state law? It's been a while since I drove in the States, but I always thought this was the rule everywhere.
Re:Traffic lights worldwide set to change after a Swedish en... by bzbarsky on Tuesday October 22, 2019 @10:13AM (#21323787)
All traffic laws are state-by-state (or even more local) in the US, in general.

In practice, according to https://en.wikipedia.org/wiki/Turn_on_red#North_America everywhere in the US has had right turn on red unless otherwise signed since 1980. Except for New York City, apparently...

Re:Traffic lights worldwide set to change after a Swedish en... by swish_bob on Tuesday October 22, 2019 @10:46AM (#21324172)
So, given the limited set of US States I've driven in, I don't appear to have been guilty of any violations.

Thanks.

> How am I supposed to know how quickly your yellow light changes on this street?

Does it matter? If you're a tourist/newcomer, simply don't try to make it through a yellow light just because you can. If you can stop, do so.

In Oregon, it's not absurd to be safe only when out of the intersection. As a "restrictive yellow" state, the yellow cycle time includes the time to completely clear the intersection. IOW, the yellow cycle time is longer than it would be otherwise.

Yes, without understanding that the yellow times are longer, it would seem absurd.

That may get you rear-ended or barely so, because the driver behind may be accustomed to the usual traffic of the area going through, and perhaps he may be the one who should stop, but is not expecting you to.

Re:Traffic lights worldwide set to change after a Swedish en... by jiveturkey on Tuesday October 22, 2019 @12:31PM (#21325602)
So you are recommending to anyone new to an area, race through the yellows? To avoid accidents??
Re:Traffic lights worldwide set to change after a Swedish en... by userbinator on Tuesday October 22, 2019 @10:06PM (#21330390)
Look at what the other drivers do, and of course look behind you.
Re:Traffic lights worldwide set to change after a Swedish en... by achow on Monday October 21, 2019 @10:48AM (#21312870)
You are right. Particularly because red light works in tandem with other lights at the crossing.

When light turns red, it does not mean other light in the crossing turns green immediately. At the crossing for sometime all the lights should be red, to cover the case of signal change after a vehicle has entered the crossing.

As a driver, you are not supposed to know this, nor should you base your driving based on this information.

It's simple: if you have enough distance to stop, you stop[1].

The yellow light is supposed to be timed so that people who don't have the distance to stop when going the speed limit would have enough time to legally pass the intersection[2].

The engineer's case (and many others) is that the lights are adjusted specifically so that this does not happen, i.e. people on a certain stretch of a road have are forced to cross on red if they don't decelerate unsafely.

[1] Your stopping distance only depends on your speed, road conditions, and reaction time.

I always thought there should be some line, marking, or sign that conveyed "if the light turns yellow before this line, at the posted speed limit you will not make the light" because it can be a hard call most of the time.
Re:Traffic lights worldwide set to change after a Swedish en... by tonyarkles on Monday October 21, 2019 @12:06PM (#21313871)
In Canada at least, some intersections (generally on major thoroughfares) have a “prepare to stop” light well ahead of the traffic light. If that light is flashing, the traffic light will be yellow or red by time you get to it. Of course, some people use this light as a reason to floor it to try to make the light...
Re:Traffic lights worldwide set to change after a Swedish en... by dsego on Monday October 21, 2019 @04:09PM (#21316706)
Newer traffic lights where I live will flash the green light for a few seconds before turning amber.
Re:Traffic lights worldwide set to change after a Swedish en... by jhoechtl on Monday October 21, 2019 @04:55PM (#21317238)
We have that in Austria since decades. It works great. They tried without the green flashing but reverted a couple of years back to flashing.
Re:Traffic lights worldwide set to change after a Swedish en... by gnicholas on Tuesday October 22, 2019 @02:19AM (#21320835)
In CA, my understanding is that you have to have "entered the intersection" before the light turns red.

The problem is, I've never known if that means entered the crosswalk or passed through the crosswalk and entered the rest of the intersection.

Re:Traffic lights worldwide set to change after a Swedish en... by qwhelan on Tuesday October 22, 2019 @04:57AM (#21321521)
The crosswalk is not part of the intersection, so it's the latter definition. For example, blocking a crosswalk and blocking an intersection are separate offenses.
Re:Traffic lights worldwide set to change after a Swedish en... by neves on Monday October 21, 2019 @10:14PM (#21319764)
The law says that you should stop at a yellow light. The yellow light is an announcement that it will become red, so a though break isn't necessary. Sure a classic law/solution that doesn't consider how humans beings think :-)
Re:Traffic lights worldwide set to change after a Swedish en... by xenocyon on Monday October 21, 2019 @06:46PM (#21318402)
The goal of the red light is to keep folks out of an intersection so that cross-traffic and pedestrians can proceed. Furthermore, in congested traffic, blocking the intersection can lead to massive gridlock.
Re:Traffic lights worldwide set to change after a Swedish en... by ppiuser on Monday October 21, 2019 @08:23PM (#21319098)
Or when that bus or truck in front of you is on its 5th gear change and still only halfway through the intersection when the light starts changing.
