Any more I missed for Los Angeles area? :)

This type of info has been available for many Metro areas in the US for quite a while from the Travel Advisory News Network.

Of course if you live in the L.A. area, you know that traffic sucks unless it's between 3:00 AM and 4:30 AM on Wednesdays.

See my list of good traffic map sites:

Traffic.tann.net/.
Sigalert.com.
Metrocommute.

(Venture capitalists take note: this would be huge in L.A.)

Here is how we do it down south ;)

Or for Los Angeles in particular, you better check it quick, there isn't usually that much green on that map. Check it around 5:30p Pacific to see how nice it is to live in LA.

Historical data would be sweet. I use tann (when it works, sigh), and have been meaning to write a scraper to accumulate data.. the theory being to profile the slowdowns, so that (should I find a nice model) I could predict near-term traffic to decide when to head out.

A friend of mine wrote a scraper for that site that would SMS him incident data, but that didn't prove very useful .. the data was usually rather stale.

However, making all the data available through an API as well as the usual pretty picture would be very nice: people will more easily come up with neat applications that way.

LA has this too based on road sensors and CHP alerts. It's a great way to avoid snarled up parts of the 405.

Los Angeles -- for years noe
