The CMU Faculty member is Sean Qian. He is in the Engineering School at Carnegie Mellon. If you need more information, can you contact me or Sean directly. You can find Sean and I at CMU, just go to their web site. I have worked on parking in Pittsburgh as well (I am at CMU Emeritus) but this particular application is something Sean Qian has implemented. Hope that helps.
The technology exists today (and yesterday, as a matter of fact) to give you real time information on available parking throughout the city. The only thing missing is support from the City of Pittsburgh and the Pittsburgh Parking Authority. The application has already been implemented and is ready to go. This is done by faculty at Carnegie Mellon.
