Oh, we got those here in Chicago, too (although they are loosely obeyed.) The traffic-signal-controlled roundabout with signals only on the through streets and not on the roundabout itself, like the on-ramp lights, I just don’t get the point of. If I have to yield to the traffic on the roundabout anyway, what is the purpose of the traffic signal? Obviously, it must be advantageous to stop the feed onto the roundabout for some reason, but I don’t quite see why. If the roundabout is so full of traffic, the feeds can’t merge into it anyway. If the roundabout is empty, what’s the point of stopping the traffic?
I’m sure there must be a logical explanation for it, but I haven’t figured it out.
When traffic is heavy in one direction, it’s difficult to enter the roundabout from the “next one round”. The lights let those drivers get a look in. In normal traffic conditions, they’re unneeded, and may not be operational.
Yeah, assuming people actually yield, I wouldn’t mind this at all. I don’t really see a need for a full three second stop, when simply slowing down to 5mph and stopping completely if there is anyone else there is sufficient. Sounds like some people have seen this done is their areas.
Where I am, Long Island, it would of course need a slight change in the definition of yield, if not in actual law, than at least in perception. I guess it’s different in other places, but here, I have never ever seen a yield sign at an actual 90° intersection. I’ve only seen it at road merges, or at T-intersections with a small turning lane that resembles a merge.
How do you know? The only experience I have with uncontrolled intersections is parking lots. Which is fine, because you know to expect that from it being a parking lot. What clues are there if it’s a regular street?
The alternative being, that you have to stop at every. single. intersection. It’s easier and cheaper to have “not right of way” (stop or yield) signs than “right of way” signs. And having signs is generally more beneficial to traffic flow than constant braking.
I don’t see the need for a stop sign at T-sections, because it’s obvious that you have to stop and/or yield if you are on the side street. But it’s still nice to have, just for clarity and consistency.
You don’t stop at every intersection here. If there’s no sign, you have to yield to the right, but that’s easy to do without completely stopping if nobody comes from there. Stop signs are very rare here (only for dangerous intersections with poor visibility, basically).
Norway is another country with very few stop signs (and when you see them, you by god STOP, because you know there’s a very good reason that involves keeping all your body parts functioning and attached to one another). If the road you are driving on is a priority road, meaning you don’t have to yield to traffic coming from the right, this is indicated by a diamond sign placed at regular intervals along the road, though rarely at the intersection itself. If you don’t see that sign, normal yield rules apply.
Norwegian traffic engineers are also very fond of traffic circles/roundabouts, and everyone knows the rules for those, as well. They tend to reserve traffic lights for high-traffic intersections where traffic circles wouldn’t work well. On the other hand, a major intersection near my house was converted a few years ago from a light-controlled intersection to a circle, and traffic flows better now.
I really do think it’s all down to driver training and driver expectations.
Oh, how I miss driving in Seattle. No, wait, what’s that other word? Dread.
See, here in Connecticut we have stop signs, but people just ignore them. That way the signs take on the role of public art exhibits. It’s all about culture.
Connecticut also used to have (don’t know if they still do) these great signs that said “Road Legally Closed. State Liability Limited.” They would put those up anywhere there was road construction, so that half the roads in the state were legally closed. Presumably the idea was to try to get out of getting sued, although I don’t know if it worked.
Where I’ve lived, we’ve never had uncontrolled intersections. As a tourist in other countries, I’ve never quite figured out when pedestrians are supposed to be able to cross the street at such places. My approach was usually to either a) wait until there wasn’t much traiffc; or b) pray to God and run like hell. Is this working as intended?
This is my situation as well. I live way out in the country where the roads are straight as an arrow. When I come to an intersection, I can literally see a mile in every direction and yet for some reason, I have to (legally) come to a complete stop even though I am assured that I’m the only vehicle within a one mile radius.
The problem is that many drivers are sure no one is coming when someone actually is.
Inattentive, lawbreaking drivers abound.
Sure. Nothing’s perfect. But when they do obey them, stop signs kill their momentum, and at lower speeds, the extra time before impact greatly increases their ability to react even if their judgment and decisionmaking can’t be improved.
I may be cynical, but I feel like it’s a risk to trust the judgment of other drivers too much, especially when there’s an inherent conflict of interest – a driver who doesn’t have to stop if he doesn’t see anyone may subconsciously tend to interpret what he sees in a way that doesn’t require him to slow down (yield).
There is so much distracted driving and general ignorance / disregard for traffic conventions and rules that ‘mindless’ measures like stop signs are necessary.
Yields don’t necessarily work that well, at least weekly I have to brake to avoid someone who ignores a yield sign and cuts me off. Heck, half the drivers on the road can’t even use merge lanes properly and are confused by traffic circles.
I think stop signs function a little like drills do for the military; it creates a behavior that is somewhat automatic. A drilled-in procedure of coming to a full stop and looking around breaks up a less attentive state of just cruising straight down a lane. Intersections require more attention and stop signs and traffic signals force that attention.
Think how often we all drift off mentally while commuting and find we are almost home and have driven most of the way in a state of limited attention - autopilot basically. I have heard that this is associated with a natural brain state (theta waves?). Driving consists of a lot of learned, nearly automatic behaviors, and traffic signals help define those behaviors for the appropriate time.
I am not going to wait five minutes for the red light at an empty intersection at 3 in the morning. I will ‘roll’ a stop sign in certain situations. But only at times when I know it is safe, and I accept the penalty of a ticket if I get caught - obviously I couldn’t have been paying enough attention if I didn’t see a cop. But I accept the necessity of the convention.
If you use that as the basis, then a stop sign isn’t safe enough either. Entering an intersection isn’t safe because there may be someone coming that you just can’t see. People can never be trusted with their own powers of observation. May as well stay at home.
Many millions of miles of driving occur every day by average people and, most the time, they don’t screw up. If we can’t trust drivers to use some prudent discretion and to trust their judgment and powers of observation, then driving itself is perhaps too dangerous for the average person.
Ah yes. I think the ordinary reasonable prudent driver should not be excessively dragged down by the lowest common denominator in the name of safety. Speed, efficiency, fuel consumption, safety, and probably a few more things, are all a big balancing act. I guess we disagree on how best to strike that balance.
Me too. Not a small town, either. The instructor took me through an uncontrolled, blind intersection, which according to the vehicle code has a speed limit of 15 mph, IIRC. Unfortunately, because of cars parked on the street blocking my line of sight, it was literally impossible to even see the intersection until you were practically in it. I finally was able to see that there was a cross street, and was about to slow down, when the instructor panicked and yelled, “There’s an intersection here”, and subsequently failed me. I thought it a rather unfair test. The instructor already knew the intersection was there.
Also, when I was growing up, changing the signals to flash at night was the norm.
