I don't know if there is a analogue to this site for major metropolitan areas where traffic density can be challenging, but in California - if you haven't seen this, you gotta check it out. It's fantastic when you're about to hit the highway and want to SEE how the flow is going, where the hang ups are... I believe if you try the pay service you get real time video as well.

It's called "SIGALERT." I found this at another site about the name:
"Sig-Alerts" are unique to Southern California. They came about in the 1940s when the L.A.P.D. got in the habit of alerting a local radio reporter, Loyd Sigmon, of bad car wrecks on city streets. These notifications became known as "Sig-Alerts." Later Mr. Sigmon developed an electronic device that authorities could use to alert the media of disasters. Caltrans latched on to the term "Sig-Alert" and it has come to be known as any traffic incident that will tie up two or more lanes of a freeway for two or more hours."

Go to <sigalert.com> and click the map of your Cali area... then you see codes on the main highways that relate to current speed, as well as flags that pop up coded for various levels of traffic accidents and hazards. If you click on one of these boxes you get a list of the accidents, etc., which you can click and expand for the CHP radio contact updates.

Cool, I'll have to try that one. I've been using

http://traffic.511.org/traffic_map.asp
and have been pretty happy.

 

Xalfa, that's a cool site as well.

I just realized this is an off-topic kinda topic - sorry bout that.
