Research by Others

National Cooperative Highway Research Program (NCHRP)

Administered by the TransportationResearch Board (TRB) and sponsored by the member departments (i.e., individual state departments of transportation) of the American Association of State Highway and Transportation Officials (AASHTO), in cooperation with the Federal Highway Administration (FHWA), the National Cooperative Highway Research Program (NCHRP) was created in 1962 as a means to conduct research in acute problem areas that affect highway planning, design, construction, operation, and maintenance nationwide.

Transportation Research Board (TRB)

The mission of the Transportation Research Board—one of six major divisions of the National Research Council—is to promote innovation and progress in transportation through research.


TRID is an integrated database that combines the records from TRB’s Transportation Research Information Services (TRIS) Database and the OECD’s Joint Transport Research Centre’s International Transport Research Documentation (ITRD) Database. TRID provides access to more than one million records of transportation research worldwide.

Caltrans Division of Research and Innovation (DRI)

Caltrans' Division of Research and Innovation, in cooperation with its partners, has developed a comprehensive program to research, develop, test and evaluate transportation innovations.

Caltrans Library

Library materials cover a variety of transportation related subjects, including engineering, planning, policy, the environment, and management.

USDA Forest Service, Center for Urban Forest Research

Five major categories: Benefits and Costs, Energy Conservation, Air Quality, Water Resources, and Fire. However, we are not limited to those five categories. Additional research focuses on Urban Forest Policy and Management, Tree Stewardship, Biometrics, Infrastructure Conflicts, and Urban-Wildland Interface.

American Forests, Trees and Air Quality

Air pollution in our cities, and even our suburbs, is a serious concern as we enter the twenty first century. Luckily, we are surrounded by efficient air cleaning machines-trees.

Caltrans, Division of Environmental Analysis, Storm Water Program

The overall goal of the Storm Water Program is to integrate appropriate storm water control activities into ongoing activities, thus making control of storm water pollution a part of Caltrans normal business practices.

Office of Water Programs, CSU Sacramento

The OWP Research Group, created in 1997, provides technical expertise and research management services for: Water quality monitoring and evaluation, Best Management Practices (BMPs), Water and wastewater treatment, Soil science and erosion control, Cost analyses, Geographic Information Systems (GIS), Water quality modeling, Technical training, Developing manuals and brochures.

Washington State Department of Transportation, Stormwater Research

Stormwater management is a complex task with a variety of regulatory drivers and constraints. It spans numerous technical disciplines including hydraulics, hydrology, geology, and water quality. For transportation projects, the extensive and linear nature of the highway network constrains the use of conventional stormwater management approaches while requiring safe access for maintenance of stormwater treatment facilities
