Do you use the 511 System?
I am interested in your experiences with the 511 - Traffic Information Service that exists (in theory) throughout the USA. In some places, like the San Francisco Bay area, one can get access to some pretty sophisticated data. Here in Las Vegas, the information seems pretty limited.
Here was a response from Moderator Bob:
I haven't used it in other states yet, but I have used it here in Arizona more than once and received up-to-date information on highway conditions that proved valuable (calls are routed to ADOT). Last week, I called to see how the fires were affecting traffic on I-17 as I left for my Utah trip. You seem to have to inquire specifically about each road you are interested in -- I didn't notice that there was an "alert" system for closures (such as the unexpected one I discovered for SR264 at Tuba City). Maybe there is and I just wasn't listening for that option, or even if AZ doesn't have that feature, perhaps other states do. Anyway, I use it and like it. I'll have to call back and see if they do have that "alert" notification option
If you dial 511 in your home town -- I would really like to know kinds of road condition information is available to you. And further, whether or not this is a help or a hinderance on the road.
Thanks,
Mark
Some interesting wrinkles in California

Nope, this is an info gathering thread -- and you have the information I want.
I have actually learned about a new wrinkle being implemented in California that is kind of cool. There are sensors imbedded in the roadways on certain key highways that measure changes in the electrical voltage that is triggered when vehicles pass over them (which establish vehicle speeds). This data is then sent to central computers that provide information on how heavy the congestion is. A visual example of this can be seen by looking at the freeways and other highways in the San Diego area. The same system is in place in the San Francisco bay area and includes a little program that estimates travel time between two points, (on-ramps and exits).
The San Diego 511 system also allows callers to locate the specific locations of buses and trains using GPS equipment mounted in the vehicles. Another version of this GPS-related traffic-tracking system is in place in parts of Riverside and San Bernardino, Los Angeles, and Ventura counties. What I like about this system, is that the little black icons (on the maps) indicate road-cam camera locations and one can see the current conditions at hundreds of locations.
Have you used it yet?
