Transportation Improvement Program (TIP)
The Transportation Improvement Program (TIP) is the regionally agreed-upon list of priority transportation projects, as required by federal law. The TIP shows estimated costs and schedule by project phase and is financially constrained based on the amount of federal, state, and local funds that will be available for transportation projects in the region. The TIP includes roadway, bridge, public transit, bicycle, pedestrian, and freight related transportation projects. The TIP is adopted by the Delaware Valley Regional Planning Commission (DVRPC), which is the federally designated Metropolitan Planning Organization for the Philadelphia--Camden--Trenton Metropolitan Area. The TIP can be amended after it is adopted and is updated every two years. For an overview of the TIP, how it was developed, and how you can become involved, see the DVRPC Transportation Improvement Program (TIP) Handbook. This guide is also available in spanish.
