INRIX's "National Traffic Scorecard"

[Duke87]

Results are out for 2009.

The top 100 bottlenecks in the US
and the top 100 congested metro areas in the US

Four of the top ten bottlenecks are on the Cross Bronx

[Scott5114]

The worst 100 bottlenecks occur in only 8 states. Hmmm...

[Alps]

The Cross Bronx should be one bottleneck.

52 55 Pittsburgh (22) Santa Monica Fwy/I-10 EB US-19/BANKSVILLE RD/EXIT 5 Allegheny PA 0.73 45 11.9

Hmm, so they are saying there is a wormhole right here in my back yard pretty much that would allow me to go directly to CA in 2 seconds?

The worst 100 bottlenecks occur in only 8 states. Hmmm...

Take note of how all but 9 of them occur in only 3 states:  California, Illinois, and New York.

I find it a bit surprising that the same study which puts D.C. at #4 for worst congestion, says that DC lacks any of the "top 100 bottlenecks".

I took note of how they did it by interchange/milepost.  Those Dan Ryan bottlenecks are just one large bottleneck from Ohio Street on the Kennedy to I-55 on the Ryan.  Part of the problem here, northbound on the Ryan, is that the connector from the Ryan to Wacker Drive was never built.  That would've removed enough cars and trucks bound for the Loop from the overburdened Circle Interchange.

Which happen to have the largest metropolitan areas of the United States. Usually the most notable exceptions are further down the list, when a 900,000 metropolitan area has worse congestion than a 2.5 million metropolitan area. (Baton Rouge vs Detroit comes to mind).

[J N Winkler]

Wichita has its worst traffic congestion at 9 PM on Monday.  Hmmm . . . .

Inrix has done a lot of fixing-up of their Web site that has their "scorecard" information on it, which is why I am reviving this old thread. 

Members of this board may wish to take a look (disclaimer:  I do not work for Inrix, but I do use their data).
