Continuing Project to Synthesize Information on Highway Problems (Superseded)

There exists a vast storehouse of information relating to nearly every subject of concern to highway administrators and engineers. Much of it is from research and much from the work of practitioners faced with problems in their day-to-day work. There has been no systematic means for assembling and evaluating such useful information and making it available to the entire highway community. The American Association of State Highway and Transportation Officials has, therefore, through the mechanism of the National Cooperative Highway Research Program (NCHRP), authorized the Transportation Research Board to undertake a continuing study, NCHRP Project 20-5, "Synthesis of Information Related to Highway Problems." This study searches out and synthesizes useful knowledge from all possible sources and prepares documented reports on specific topics. Reports from this endeavor constitute an NCHRP report series, Synthesis of Highway Practice. Each report is a concise document pertaining to a specific highway topic. This staff digest reports on the progress and status of NCHRP Project 20-5. It includes five tables: (1) Topics Being Studied; (2) Synthesis Topics Selected for the FY 2002 Program; (3) NCHRP Project Committee SP20-5; (4) Completed Syntheses; and (5) Index to Syntheses and Studies.
