I use this app a lot ... good traffic predictor

I use this app all the time and I used it in both Northern and Southern California. Its very accurate and allows me to gauge traffic conditions and make decisions quickly.

I know California freeways like the back of my hand. For me its easy to read, but other people may find it less so and want to use their GPS/Waze.

I find the Waze map interface to be horrid. Sigalert gives me a complete picture all at once.
