National Research Programs

Caltrans partners with national transportation organizations and benefits from leveraging research conducted at the national level.

Transportation Research Board

TRB, the major national multimodal transportation research organization, brings practitioners and researchers together to solve critical transportation problems. With more than 200 standing committees, almost every transportation mode and topic is represented. Each committee proposes research, shares research findings, sponsors special activities, and provides a forum for transportation professionals to discuss current and future transportation issues.

The TRB's major sources of revenue are state departments of transportation, federal agencies, other transportation organizations, and TRB self-generated revenue. With a contribution of $538,409 in 2021, Caltrans was able to leverage $28 in research-related activity for every $1 invested.

This beneficial investment in TRB enables Caltrans to:

  • Have a voice in setting national research priorities and agendas

  • Access user-oriented research

  • Avoid duplication of research effortss

  • Support the uniform, practical, and common-sense application of transportation research results

  • Develop a more informed and forward-thinking workforce

  • Improve customers’ experiences by accelerating the development and implementation of solutions to problems that affect transportation planning, design, construction, operation, and maintenance

  • •Retain employees by offering stimulating and professionally rewarding opportunities to participate in efforts that help improve the nation as a whole

Cooperative Research Programs

The National Cooperative Research Programs address research on safety, planning, design, construction, operations, and maintenance at the national level. This research includes developing and evaluating new technologies and techniques. The programs also foster sharing best practices among states.

Caltrans leaders work with the following national research programs:

  • National Cooperative Highway Research Program (NCHRP)

  • Transit Cooperative Research Program (TCRP)

  • National Cooperative Freight Research Program (NCFRP)

  • Airport Cooperative Research Program (ACRP)

In 2021, the NCHRP selected 59 new projects for funding, of which 29 were important to Caltrans. Caltrans staff is currently serving on nine of the new project panels. As project panel members and a member of the Special Committee on Research and Research Advisory Council, Caltrans is able to influence national projects to directly benefit California.

Transportation Pooled Fund Program

When significant or widespread interest is shown in solving transportation-related problems, several federal, state, regional, and local transportation agencies, academic institutions, foundations or private firms might jointly fund research, planning, and technology transfer activities. The Transportation Pooled Fund (TPF) program combines resources to support transportation research studies.

Caltrans Membership on TRB Committees

The Transportation Research Board (TRB) promotes innovation and progress in transportation through research. TRB is one of seven program units of the National Academies of Sciences, Engineering, and Medicine, which provides independent, objective analysis and advice to the nation and conducts other activities to solve complex problems and inform public-policy decisions. The program is supported by state transportation departments, federal agencies, including the component administrations of the U.S. DOT, and other organizations and individuals interested in the development of transportation
