State Transportation Improvement Program

MPOs and RPOs each develop a Transportation Improvement Program (TIP) at the regional level, which are combined with the Interstate Program and Statewide Program to become the Statewide Transportation Improvement Program (STIP). The STIP reflects the first four years of the Twelve Year Program (TYP). 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.
