Yeah, we have a system here at MARTA. It's not public however. The infrastructure of 2-way radios for position reporting also supports police, operations and maintenance communications with push-to-talk; but, it cost many millions using 800 MHz trunked radios.
I contend that 3G cellular using mobile routers is far more cost effective than a dedicated infrastructure for position reporting only. And it's easy to distribute to the public if you're using Google.
