But let's get back to the I-75 in Atlanta. It is on level -1, with a lot of overpasses, and even parking lots on top of it. The I-20/I-75 interchange is locally known as the spaghetti interchange. (Birmingham is not the only city with such an interchange )

The Downtown Connector is when I-85 and I-75 combines as one interstate. The I-85/285 is known as the spaghetti junction not 75/20 there is no such thing.

Indeed, the 85/285 freeway interchange is also called spaghetti junction.

To be frank, the 20/75 interchange looks more spaghetti then this one, since this one is a quite standard 4/5 level stack.

There are only two HOV exits on the downtown connector, one in each direction. Except for them, all exits are on the right. We change lanes like that because, well, just because.

Great movie. Something that really strikes me is the bad anticipation to other traffic, considering the huge amount of unneccasary braking lights... If I would see that on a motorway here, I'd immediatly be alarmed.

Nah, watch it in Dutch traffic. People brake all the time for nothing, let go the gas would do the same. It creates an unnecessary chain reaction effect.

Yeah, indeed. I don't get irritated in traffic very fast, but those are one of the things which create unnecessary much stress. You cannot see on the braking lights whether the driver is braking just a little bit or that he's making some emergency stop.

I have a question to Atlantan forumers;

why has the traffic volume dropped from 349.000 in 2004 to 286.000 in 2006 on the I-75/I-85 duplex? That's quite a significant drop!

It hasn't. As I understand it, traffic counts there aren't done by cables in the road, but by software that interprets video images from traffic cameras. The cameras and software are pretty good at assessing traffic conditions, but they suck at actually counting cars.

IIRC, at one point a few years back the traffic 'counts' went up to over 400k. Actual traffic volumes didn't get that huge, either, which is a good thing considering Atlanta's problems with meeting air quality standards. At the time I did ask GDOT WTF, and what they told me then is what I'm telling you now.

Okay, thanks. And what is the correct number? 300k+ is more California-like.

I donno, but 300k seems about right.

I think it also has to do with the fact that most cars in North America use automatic transmission. In heavy traffic where the average speed is low, simply releasing the gas or switching to a lower gear is very effective at reducing speed quickly on a manual transmission, but in an automatic the coupling between the engine and the wheels is loose at relatively low speeds, and using the brakes may be necessary. Also, if a driver sees someone brake ahead, he/she might tap the brake slightly to make sure that the driver behind is aware as well.

Personally I like to keep a larger-than-usual distance from the car ahead of me when the traffic is moving very slowly, so that I don't have to press the brakes until I come very close (which works well even with an automatic transmission), but many drivers don't do that.

Its because Americans love to hog faster lanes.

Currently, I-75 is 15 lanes wide north of the Windy Hill Road interchange (8 northbound, 7 southbound), and as such, is the widest freeway in the United States.

The project plans to expand the freeway from I-285 northward to the Wade Green Road interchange, making it to 26 lanes (13 lanes each both northbound and southbound) at Windy Hill.
that's impressive.

Goggle earth is inaccurate sometimes. First of all they have it listed as 20-75 interchange when it's supposed to be 20-85/75. The spaghetti junction (85-285) is indeed larger that the 20 interchange.

Here's the difference between the two.
