PennDOT appears to have four regional traffic management centers that monitor the various systems in place (cameras, ITS, etc).
Southeast Region RTMC covers just D6.
Eastern Region RTMC Is based in D8, and also covers D5, and D4.
Central Region RTMC is based in D2 and also covers D3 and D9.
Western Region RTMC is based in D11 and also covers D1, D10, and D12.
PennDOT also has a statewide traffic management center in Harrisburg.
All of these used to be referred to as traffic control centers. TCC should be the statewide talkgroup.
Here are a couple links to give an idea how these facilities operate.

PennDOT worked with local 911 centers to share information and alert motorists of roadway incidents faster.
