Under the role of Regional Transportation Planning Agency (RTPA), SJCOG is responsible for developing the region’s funding priorities for the State Transportation Improvement Program (STIP) and for submitting the projects to the California Transportation Commission (CTC) by way of the Regional Transportation Improvement Program (RTIP).

The Regional Transportation Improvement program (RTIP), which is updated every two years, spans five years and includes a list of highway, local road, transit, and active transportation projects the San Joaquin region proposes for funding.

The primary purpose of the RTIP is to help implement the San Joaquin region’s adopted long range Regional Transportation Plan and Sustainable Communities Strategy (RTP/SCS), which guides the region’s transportation investments over a 20 to 25 year period. The RTP/SCS is developed through an extensive public participation process and reflects the unique mobility, sustainability, and air quality needs of the San Joaquin region.

The projects contained within the RTIP will help enhance the environment for existing and future generations; maximize mobility and accessibility; increase safety and security; preserve the efficiency of the existing transportation system, support economic vitality; maximize cost effectiveness; and improve the quality of life for residents.
