There are a lot of decaffeinated brands on the market today that are just as tasty as the real thing.

Finally. I grew up there, and was really confused when I moved down south at these weird non-sequential exit numbers. But Iíve grown to love them, and get confused when I go back north now. Some of my Boston friends are bitching about it because itís going to be confusing, but theyíve never lived anywhere else. Theyíre also the same ones who claim to love snow and Boston winters and couldnít imagine living somewhere that has moderate winters, so I canít trust their opinions.

One cool thing I've noticed being rolled out in Toronto is that the walk lights at some intersections go on before the green for traffic.

NYC does this too throughout the city at what seems like random intersections. I've also noticed that some taxis have learned this behavior and know they can run the red light longer at the cross street. And tourist can't understand tens of different lights at one intersection, which means they'll go through the red light because the crosswalk light turned on. And cars further back see the crosswalk light on and begin honking because they think the front car isn't moving on the green light.

An early start, we call it here. Not sure what US traffic engineers call it. It's a fairly low cost improvement as it shouldn't need physical changes, just software changes. Unless the infrastructure is ancient.

Leading pedestrian phase

And the cost is traffic throughput! There's a handful at high accident locations in my city, though.

I've usually seen LPI, leading pedestrian interval. Nice thing in NYC is that they recently legalized bikes to take the pedestrian light and beat cars through the intersection.

Another way to put that is that the cost is that car drivers take marginally longer to get to their destination.

Assuming that those two roads both take a fair amount of traffic, is there anything particular that's wrong about making a roundabout there?

I mean, I can see that it takes up a lot of space compared to a level intersection, but it doesn't seem like an expensive piece of real estate. Roundabout should be quite a bit safer and have better throughput, no?

When you have a signalized intersection that goes over capacity, particularly if it's one of the most busy/important intersection in the vicinity, when you push it further over capacity, you tend to get much worse results than you would expect. This is because traffic demand continues to queue up from the approaches, while a smaller and smaller percentage of the standing queue is cleared each time. You then get gridlock as drivers fail to clear adjacent intersections, and suddenly even the alternate routes that could avoid that intersection are awful.

This is not to say that pedestrian safety should be ignored, but that the traffic mitigation that is required can be massive.

I was not being facetious when I said that roundabouts should always be considered. This particular roundabout has a lot of bypass lanes, so you get less pedestrian/bike safety improvements than you normally would, but it's in the middle of nowhere so it's probably not a problem.

Things that make you not build a roundabout :

1. Costing too much due to real estate, utility relocations, weird intersection geometry
2. Unbalanced traffic volumes in particular configurations, or otherwise volumes that make the roundabout need too many lanes
3. High percentage of truck or other large design vehicle that cannot make one of the movements due to geometry

What exactly are the pedestrian/bike safety improvements that you "normally" get with roundabouts? My understanding is that it's fairly established that they decrease pedestrian and bike safety.

Utah loves roundabouts. We put them on top of our parking structures and in the middle of our rail lines.





... and then there's this mess, where someone managed to play Cities in Motion with actual infrastructure. Let's combine a SPUI with some frontage roads, an offset-T and a continuous flow intersection. Eh, gently caress it, let's give it a roundabout as well.

Oh for sure, I've read that one. But that depends on 1) Dutch road law which places the onus on drivers not to hit pedestrians and cyclists and 2) actually designing both the roundabout and the surrounding infrastructure to Dutch standard. I'd love for both to be the case, but in the North American context a roundabout is just giving drivers greater opportunity to scream through a crosswalk at high speed without checking if there's anyone in it.

Local roundabout to nowhere check...




This was built in 2013 with the intention of connecting 2 business districts, and hopefully creating a 3rd. They ran into many obstacles, as such projects tend to do. The first phase was finished in 2015. It took until 2020 to finish acquiring right-of-way for the second phase. Supposedly to be completed in 2022.


It has been in this state since about 2015, the road just ending.



When done it will take more or less this path, snaking right between the bank and the burger king. The burger king's parking lot and drive-through has already been relocated and a building in the way torn down, so maybe they might actually hit that 2022 date...

Skagit County has a lot of roundabouts but these two are the best.


You might think that these are entrances to the lumberyard but they've both been blocked for as long as there have been roundabouts here. My guess is that the city built them assuming that the roads will eventually be connected once the lumberyard shuts down.

Also, I'm a bad person because the diagonal road is called F&S Grade Road and in my head that automatically gets converted to "gently caress & Suck Grade Road".

The Arboretum is technically the entire University of Utah campus. Why the marker is in the middle of the medical center by the light rail station, where there are few trees... who knows?

What requirements are there for fences ~10ft off the road? Someone nearby wants to build 24x24 columns for a fence along the road, which seems like a hazard.

$300 if you want to be sure

Roadside Design Guide

But short answer is, depends on speed and traffic volumes. Send a street view of the road and the speed limit and we can guess

10 feet is ~probably~ fine

Note the streetview is a few years old - they've already built the pillars that you can see in satellite view. It's a 45mph road.

I think the pillars are ~4ft tall, they're planning on doing some kind of solid fence between them.

The whole thing is super creepy from the ground - they're essentially building a compound in the middle of a residential area.

I see like 24 feet from the edge of the travel lane (which is what we would measure) if the below image is what you're talking about

It's almost certainly fine.
