Much of the research conducted by the NCHRP is designed to solve specific problems experienced by practitioners that are related to the operational and planning functions of state transportation agencies. Although top management is certainly affected by these problems and benefits from solutions through improved agency performance, this type of research does not necessarily address top management's most immediate needs. NCHRP Project 20-24 conducts research intended to address the specific concerns of chief executive officers (CEOs) and other top managers of the state departments of transportation (DOTs). The American Association of State Highway and Transportation Officials (AASHTO) Standing Committee on Research (SCOR) each year allocates funds to the overall series, but identification of specific tasks is left up to the NCHRP 20-24 project panel.
An initial research effort to design the research series was completed in 1988 (Apogee Research Inc. Richard R. Mudge and John A. Clements, PIs). Through surveys and interviews, issues of greatest concern to top management were identified and initial projects were developed to address these issues. Principal findings and details on a recommended program of specific projects were presented in the agency final report titled, "NCHRP Project 20-24, Research Program Design." The agency report was distributed to NCHRP sponsors only. However, others may purchase copies for the cost of reproduction.
Success in that initial research motivated continuation of the NCHRP Project 20-24 series. Consultant services for NCHRP 20-24 research was for several years secured typically through limited competition or sometimes by sole-source requests. These mechanisms may from time to time still be used when warranted by the particular nature of the research to be conducted. (See NCHRP 20-24B Task-Order Support for Research on the Administration of Highway and Transportation Agencies). For the most part, however, projects in the NCHRP 20-24 series are procured and conducted under the same procedures and requirements applied to other NCHRP research. Individual projects in the NCHRP 20-24 series have been allocated funds and conducted as described in the specific project pages listed separately. Please refer to the listing below or search for particular projects to see these descriptions for further details. Reports and other research products typically are not published as part of regular NCHRP document series but are made available for review and download through links on individual project web pages. This link is a preconfigured search that will list all publications.
