State Transportation Improvement Program

First Four Years - The TIP

MPOs and RPOs each develop a Transportation Improvement Program (TIP) at the local level, which reflects the first four years of the Twelve Year Program (TYP). The Statewide Transportation Improvement Program (STIP) covers the entire state and includes the 24 individual TIPs representing each Planning Partner. Federal Law requires TIPs to be updated at least every four years. Pennsylvania’s MPOs and RPOs update their TIPs every two years during the TYP update process.
