Transportation Improvement Program

Who creates it?

Metropolitan and Rural Planning Organizations (MPOs and RPOs) create local TIPs that include all the projects for a region. PennDOT creates two statewide-managed TIPs that span multiple regions including the Interstate Management Program TIP and Statewide Initiatives TIP.

When is it updated?

Pennsylvania TIPs are updated every two years. The 2025 Regional TIPs are currently being updated. The Draft Regional TIPs were available for 30-day Public Comment Periods from March through June 2024.

How does it impact the planning process?

PennDOT combines the 24 individual regional TIPs with two statewide TIPs to create the Statewide Transportation Improvement Program (STIP). The STIP is also the first four years of the 12-Year Program.
