A normal sign might make people think only the left lane can’t right on red, but those signals look to be set up to prohibit all rights on red

Apparently it's a thing in some Florida counties to prevent cars sitting in the crosswalk while attempting to turn right on red. The signal comes on when someone hits the crosswalk button. mentioned briefly on page 22 of this pdf from Pinellas https://forwardpinellas.org/wp-content/uploads/2016/08/Pinellas-Pedestrian-Safety-Action-Plan.pdf quote: Evaluate traffic control options to reduce left and right turn movement Peanut President fucked around with this message at 00:17 on Mar 31, 2020 |

Peanut President posted:Apparently it's a thing in some Florida counties to prevent cars sitting in the crosswalk while attempting to turn right on red. The signal comes on when someone hits the crosswalk button. This is correct. For another example, the traffic light on McKinley Dr @ Fowler Ave in Tampa, FL does this. The no right turn signs illuminate when pedestrians have a walk phase across the right turn lanes. Old install from 10+ years ago, still rare and only found at intersections that have problems with ped collisions.  Here's a newer double right with the same controls, N/B Grand Cypress @ SR56 in Wesley Chapel, FL. This one is box span, also a monster of an intersection... has both nearside and farside traffic signals, due to the intersection being exceedingly wide. 33 signal heads, emergency pre-emption, and that lone light-up no right turn fixture.  Triple right turns have a hard no right turn on red prohibition. Another monster intersection, E/B Bloomingdale Ave @ US 301 in Brandon, FL:

Being allowed to turn right on a red signal seems deeply wrong to me. In Norway it is not allowed. How common is it outside the US?

pun pundit posted:Being allowed to turn right on a red signal seems deeply wrong to me. In Norway it is not allowed. How common is it outside the US? The first one is with an additional green arrow traffic light. With this one, if you have a green arrow, there aren't any cars from other directions that can come into conflict with turning right.  The second one is with an additional green arrow sign. With this one, you have to make sure no cars are coming, but you can turn on red.  There are more and more intersections that have signs of traffic lights like this, but the vast majority don't have that. And obviously they are only added where it is deemed safe.

Today on my walking commute home through the Perth CBD (West Australia) all the traffic signals with pedestrian crossing had big stickers on them above the buttons stating that the City of Perth Council and Main Roads WA had switched all the intersections to automatic traffic/pedestrian cycling between 7AM-7PM. This means you don't have to press the button for pedestrian crossing (Some of the intersections definitely required that outside of peak transit times). A good idea IMO to prevent roni transmission, anyone heard of other cities implementing it? Honestly for some main intersections like St Georges Tce/William St it was probably unnecessary as that already cycled between pedestrian and traffic all the time but the big stickers they put up on the poles are extremely good.

Some places you can't unless a sign says you can (NYC), some places you can't if it has a red arrow light, and some places let you turn right on red, even with a red arrow on, as long as there isn't a sign stating you can't. I got passed by a semi truck on the left at an intersection with two right turning lanes when I was in the right most lane with a red arrow light on. I was like "wtf" so I looked up that state's laws and apparently that is fine unless there is a sign say no right turns on red. That just feels so wrong to me that I'm not going to do it as I'm not in those states very often and I don't want to be in a bad habit.

You can also make a left on red in some places. If you're on a one-way street, turning left onto another one-way street

Indiana can turn right on red but you have to wait for any pedestrians (peds in crosswalk have ultimate right of way in Indiana for all the good it does) you sometimes get stuff like this, a crosswalk in the middle of a street so peds can cross safely  Peanut President fucked around with this message at 18:17 on Mar 31, 2020 |

Either that, or a full traffic signal designed to completely stop traffic.

It's a pretty trivial change to make (in many city CBDs that will already be there case during peak times), assuming there city doesn't have incredibly outdated signals hardware/software, or the city isn't incredibly hostile towards pedestrians.

Make a 180 towards the sidewalk, bike the gently caress away, and take the nearest non-car carrying exit. If caught on camera, claim you were startled and panicked.

Why are there some 4-way intersections that only have three crosswalks? Is it always a case-by-case basis or are there some general rules that make it advantageous? here are some examples:  https://www.google.com/maps/@39.3982367,-84.5471214,134m/data=!3m1!1e3  https://www.google.com/maps/@39.3520721,-84.330771,213m/data=!3m1!1e3  https://www.google.com/maps/@43.0209687,-85.6886807,174m/data=!3m1!1e3 Groundskeeper Silly fucked around with this message at 18:43 on Apr 8, 2020 |

Somebody sitting at a desk decided it's fine for other people to walk three times as far to get across the street, probably? We have a few of those here and they are completely ignored. e: here's a local one I DO know the reason for:  It's that way because 6th and 7th are one way, and there's a godawful interchange just south, so A LOT of people who need to go south on 6th have to go north on 7th then hang two lefts, like so:  Even without the crosswalk, M will back up from 6th, some moron will inevitably block the box on 7th and M, and then the left lane of 7th backs up down to the bottom of the pic. It's also pointless since people just walk across with impunity, so they may as well just paint one at this point. I wish they'd sit a cop at 7th and M to just slap tickets on windshields when motherfuckers enter an intersection they can't leave, which is the actual problem here. Or ED a strip of the car lot to make a dedicated left lane, maybe. Javid fucked around with this message at 19:11 on Apr 8, 2020 |

If you omit one of the crosswalk legs, you don’t have to have an extra phase for pedestrians on that leg that would conflict with cars that need a green arrow. Lets you get more vehicle capacity with the same amount of pavement. These days we pretty much never do it, since multimodal design has become popular, but it was pretty common 15 or 20 years ago in my area.

Lets you get more vehicle capacity with the same amount of pavement. Yeah there's one of these on my bike commute. It's extra annoying given that the intersection lies between a transit station and a medium-density neighbourhood, so it's actually a fairly busy pedestrian route. They obviously made it that way so as to have an extra turn signal phase, but it's still not great. The bike route it's part of was designed in the 80s, though, so it's full of this sort of poo poo.

Traffic already gets backed up waiting to turn left at those spots, it makes sense that they don't want any pedestrians in that part of the intersection slowing it down even more. Thanks!

Yeah the one I was referring to was Clark and Great Northern Way. At the very least, I've heard they're planning on running a bike/pedestrian bridge alongside the Millennium line when they extend it. (Sorta like the Canada Line bridge to Richmond.) So that should hopefully improve things.

There was one at a super-busy intersection near me, with a 2min30sec cycle length, so it could potentially take you 7 and a half minutes to get through the intersection as a pedestrian, if you really wanted to go between the two worst corners.

Pretty sure you can export to csv, a comma delimited file that Excel can import no problem Are you meant to be doing sanity checks or other stuff that’s important for a junior engineer to learn?
