The Office of State Planning (OSP) builds and maintains partnerships within the Department and with other governmental agencies and the private sector to ensure a safe, sustainable, and efficient transportation system that achieves the three Es:

  • Economic Prosperity
  • Quality Environment and
  • Social Equity

California Transportation Plan

The Office of State Planning facilitates the development and preparation of the long-range California Transportation Plan (CTP) required by federal and State law. The CTP provides a common framework for guiding transportation decisions and investments by all levels of government and the private sector. Federal law and state law require the development and preparation of a state transportation plan. OSP also provides analysis and policy recommendations regarding current transportation issues and future trends.

California Transportation Plan (CTP) Guidelines

OSP is responsible on behalf of Caltrans to prepare the very first California Transportation Plan (CTP) Guidelines in cooperation with the California Transportation Commission (CTC). The CTC is authorized to adopt these guidelines for the preparation of the next CTP. The document is not intended to serve as a step-by-step guide for preparing the CTP, but rather, serve to identify statutory requirements for the plan and inform the development of the plan by advising study areas for analysis and evaluation to ensure the CTP provides long-term, inclusive planning policy for the State transportation system.

California Interregional Blueprint

OSP is expanding the State's transportation planning process to include the development of a state level transportation blueprint focused on interregional travel needs. The California Interregional Blueprint (CIB) will articulate the State's vision using Geographic Information Service (GIS) and modeling tools for an integrated, multimodal transportation system. This system will complement regional transportation plans and land use visions. The CIB when fully developed will become the foundation for the CTP.

Statewide Transportation Projects Inventory (STPI)

The Statewide Transportation Projects Inventory (STPI) is the updated collection of statewide multimodal transportation projects’ geospatial data in a repository. STPI displays the current transportation system along with future multimodal projects. The repository contains constrained planned project data from the 44 MPOs and RTPAs adopted Regional Transportation Plans (RTPs) and programmed project data from the California Transportation Investment Program System (CTIPS) database when combined will provide a stand-alone GIS tool that displays both current and future investment over the next 20-years. STPI will be a the multimodal planned project layer(s) accessible at the Caltrans GIS library in sumner 2016.

Economic Analysis Branch

Part of OSP, the Economic Analysis Branch, provides transportation decision makers with expert economic and financial research, analysis, and information to ensure the productive and efficient use of public resources.

Native American Liaison Branch

This program works to help California Native American communities identify and implement transportation safety solutions that will lead to improved safety for all – motorists, passengers, bicyclists, and pedestrians. These assessments will be highly focused, in-depth, expert safety reviews of problem areas and specific recommendations for safety improvements within their jurisdictions, as well as on the roadways accessing their land. They also help Tribal governments identify potential sources of funding to make the improvements, and establish the justification to use in future grant applications.
