State Planning


The Office of State Planning (OSP) provides a framework and collaborative process to understand and shape the future of the transportation system in California in the context of broader economic, demographic, environmental, technological, and equitable issues. The program facilitates innovations in transportation and a system that is integrated and multimodal, serving all Californians.

The Office of State Planning builds and maintains partnerships through an open and collaborative planning process by supporting early and continuous communication and identifying shared interests with affected government entities, agencies, transportation partners, other stakeholders and operators, community-based organizations, and the public.  This collaborative and inclusive effort provides Californians an opportunity to step back and look at the big picture to consider the future transportation system on a statewide basis.

OSP consists of four branches that all coordinate and collaborate with various stakeholders to produce comprehensive studies and guidelines, conduct tribal outreach and economic analysis, and develop the California Transportation Plan.  OSP strives to create a blueprint that helps plan for a sustainable, multimodal transportation system.

Please see below for more information on OSP’s branches and deliverables.

Statewide Long-Range Planning Branch 

The Statewide Long-Range Planning (SLRP) Branch provides support and technical assistance for statewide transportation planning. One of the key responsibilities of the branch is the development and implementation of the California Transportation Plan (CTP), the State’s long-range, multi-modal transportation plan. The CTP provides a forward-thinking policy framework for guiding transportation decisions and investments by all levels of government and the private sector. The SLRP Branch works with internal programs to implement long range planning consistent with CTP and forge partnership with external  partners to explore solutions for California’s complex transportation network.   The branch also engages in scenario planning, tracking emerging technologies, managing state planning resources and research on various transportation issues in support of state planning. Major branch deliverables/activities include:

  • CTP
  • Caltrans Future of Mobility White Paper
  • Research White Papers and Best Practices
  • Scenario Planning
  • Statewide Transportation Projects Inventory
  • Legislative Analysis and Coordination
  • Interagency and Regional Coordination
  • District Coordination
  • Modal Plans and Program Coordination

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.

Caltrans Future of Mobility White Paper

OSP worked with the UC Berkeley's Transportation Sustainability Research Center (TSRC) on the Caltrans Future of Mobility (FOM) (PDF)  white paper. The objective of this project was to explore the impact of technological, social, economic, and environmental change on Caltrans' long term planning process for transportation in California. The results from this study will ultimately be used to inform the scenario development for the CTP 2050.

Statewide Transportation Projects Inventory

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 contains multimodal planned project layer(s) accessible at the Caltrans GIS library.

Strategic Engagement and CTP Implementation Branch

The Strategic Engagement and CTP Implementation Branch in the Division of Transportation Planning works in coordination with the twelve Caltrans district offices in order to guide and assist in the outreach of the CTP to ensure that the long range planning document gains exposure to the regional and local government stakeholders as well as the general public, in order to attain valuable feedback and public opinions that should be considered within the document. In addition, this branch also works with internal and external partners to identify and develop policy opportunities to maintain high visibility and credibility for State Transportation Planning efforts. Branch deliverables and activities include:

  • CTP Implementation
  • CTP Guidelines
  • Public Participation Plan
  • Public Outreach

California Transportation Plan Guidelines

OSP was 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 was 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. This document serves to identify statutory requirements for the CTP 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.

Public Participation Plan

The Public Participation Plan (PDF)  (PPP) for the California Transportation Plan (CTP) and Federal Statewide Transportation Improvement Program (FSTIP) supports Caltrans mission to involve stakeholders and the public in transportation decision making and responds to federal and state laws and regulations that require public engagement.  The PPP describes Caltrans’ strategies and techniques to inform and engage stakeholders and the public in transportation planning and programming with the purpose of maximizing participation and effectiveness.

Transportation Economics Branch

The Transportation Economics Branch provides transportation decision makers with expert economic and financial research, analysis, and information to ensure the productive and efficient use of public resources. Major activities of this branch include:

  • Policy Analysis and Research
  • Life-Cycle Benefit/Cost Analysis
  • Economic Impact Assessment
  • Economic Research and Modeling
  • Data Forecasting and Estimation
  • Transportation Funding in California

Native American Liaison Branch (NALB)

The NALB provides leadership and direction for the Department’s effort to improve the government-to-government relationships with Tribal Governments by serving as a liaison between Caltrans; the 109 Federally-recognized Tribes in California; state, local and regional transportation agencies; and other key stakeholders. NALB facilitates compliance with Departmental policy and federal statutes and regulations requiring that Tribal Governments be involved in transportation planning and programming processes. Please visit NALB’s website for more specific information on this branch.
