Sigalert.com Los Angeles Traffic Map

I've been checking it several times over the last few days and it doesn't seem to match my experience with congestion on the freeways. Maybe it feels worse in the car though.

i personally prefer google maps, but sigalert is usually pretty good. i think both use the same CHP source to report accidents, but i prefer google's method of tracking traffic through cell phones rather than sensors on/near the freeways used by sigalert. this also allows google maps to show traffic patterns on major streets in addition to freeways. sigalert is very limited in the non-freeway traffic info that it provides.

My sentiments exactly. You're definitely doing yourself a big favor if you check GoogleMaps traffic before heading out.

Google maps can track people via their cell phones? Coolest use of gross privacy invasion I've heard of!

I've also found sigalert inaccurate.
My approach.... get on freeway but have alternate routes with surface streets planned if congested.

Quite often I'll have some family member on the phone asking me why they've been in a parking lot on the freeway for the past 20 minutes. I'll then check Sigalert's site and they're showing green. I check Goog first now, but even they aren't immune to the above situation, as I found out last week. However, they're correct way more than they're wrong.

I suspect they're all getting their data from Caltrans so data problems affect them all. I have found that Bing Maps' color coding often seems more accurate than Google's. For example, it'll be bumper to bumper and Google might show yellow while Bing shows red.
