: You were right the second time, it is KNX. Believe it or not, I also
: listen to KNX in the evenings here in Colorado! It's kind of fun driving

: original question. Yes, there are sensors just past every on-ramp and
: off-ramp on the freeways. They're the same sensors used at most stoplights
: now (coils in the pavement). You might want to give CalTrans a call or
: even ask Bill Keene (KNX's traffic reporter). I doubt if just anyone can
: get the information, but it would be worth asking just in case you can
: get it.

I seem to remember that they sell the information (and a computer connection)
to anyone willing to pay.

On the subject of the pavement sensors, can anyone tell me more about them?
