Which Neighborhood Has Most Traffic Congestion?

Every year the city conducts a traffic flow study, which measures the number of cars that go down a particular street during a typical day.

Some interesting stats from 2006:
Cars per day that drive through Ranier & Jackson -- 30,900
Cars per day that drive over the Montlake Bridge -- 56,800
Cars per day that drive through Queen Anne Ave N. -- 11,900

Car Traffic vs. Bus Traffic:
Cars per day that drive on E Yesler between 14th and 23rd -- 8,700
Number of 27 buses per day that travel that same route -- 70 (35 each way)

Cars vs. Population :
Cars per day that drive over the West Seattle bridge -- 109,900
Number of people that live in West Seattle -- 102,761
(Defined as the four WS zips 98106,116,126,136 + WhiteCenter 98146 -- 2000 Census)

Clearly this last stat is mind-blowing. More to come.

Check out the traffic flow stats yourself.

And see this interesting article suggesting why Vancouver has more public trans usage than Seattle or Portland.

Hah! Nice connection. Wonder what Tufte would say? I saw him talk about the Minard map for about 45 minutes in a lecture once... he was practically foaming at the mouth he loved it so much.
