Hey BB! From what I know, here's the breakdown post-July 1, 2009:
Metro: All Citadel stations (WBAP, KSCS and KPMZ; KSPN is still not taking traffic, far as I know, except possibly during pre-local Cowboys games--but that may have ended with the demise of the Traffic Chopper as we know it

all CBS stations except KTVT-TV; all Salem stations; all Service Broadcasting stations; and a few odds-and-ends [KAAM, KXAS-TV, KEOM, the Mortenson stations, etc.) Metro, via Metrosource, farms out PT news anchors to KRLD and WBAP.
Traffic.com: WFAA-TV, KTVT-TV, KERA-FM (and likely KKXT,) KLAK, and the Cumulus stations (KTCK and KLIF-AM/FM, but not including KPLX--which I'd guess still uses the Traffic.com product but has the jock read them.) I believe they still have the Radio One stations, but, same as KPLX, they use their own reporter or jock. Far as I know, Traffic.com doesn't supply any news people (ala Metrosource.) They might still farm out one PT news anchor to KLIF-AM, but none to WBAP.
Total Traffic: Clear Channel stations only.
Fun stuff:
As of July 1, 2009, there are no more choppers in the air that are dedicated only to traffic.
WBAP no longer has any traffic people on their payroll.
Metro runs ONE 4-seater plane to service all of those stations...so yes, you have WBAP and KRLD riding shotgun. And I won't tell you where Laura does her reports from. Metro apparently promised to put a second plane in the air as part of "stealing" the Citadel contract...but we're all still waiting to see that happen (Maybe Tyler should sue for breach of contract? Void out this Metro disaster and get things back to normal with Traffic.com? Hmmm? Hmmm?) Nah, Metro WILL come through---just a few more trips to the Airplane Junkyard for parts and they'll have one pretty much ready and pretty much ok to fly. (And, if there's any doubt, the FAA will inspect it every 1,000,000 hours.)
Tarrant reporter Monty Cook and Collin/Denton reporter Michael Scott ride side-by-side in the same plane. That would be the same story for KRLD's Tarrant and Collin reporters...so let's blow that illusion right out of the water (like anyone's surprised.) Scott also got jerked around by having his time compromised with The Dorsey Gang by having to do WBAP reports (that's how you justify salary demands---pile more work on someone.) Hell, ALL the Traffic.com folks who gravitated to Metro got jerked around, with pay cuts of 10% up to 50%. (But I guess that's what you get when you go from a well-funded, secure company to one that's worth pennies and has been "pink sheeted" by the SEC. But hey, we all gotta eat, right?)
Metro apparently still plans to shutter all but 18 of their national offices, and create "regional traffic hubs" instead. So, you'll have reporters in Dallas doing traffic in KC, Houston, SA, etc (and I believe they're doing some of those cities already.) I have a friend-of-a-friend in Houston who's doing EIGHT different stations' traffic reports himself every day. Where is the love?
Metro = The Ramen Noodles of Broadcasting
And Jane Dornacker is still dead.
