Continuing Project to Synthesize Information on Highway Problems (Superseded)

This staff digest reports on the progress and status of NCHRP Project 20-5, Synthesis of Information Related to Highway Problems, for which the Transportation Research Board is the agency conducting the research. This study is intended to search out and synthesize useful knowledge from all possible sources and to prepare documented reports on current practices in the subject areas of concern. Reports from this endeavor constitute an NCHRP report series, Synthesis of Highway Practice, that collects and assembles the various forms of information into single concise documents pertaining to specific highway problems or sets of closely related problems. Five tables are presented in this digest showing the following: (1) Completed Syntheses; (2) Topics Being Studied; (3) NCHRP Project Committee SP20-5 Members; (4) Synthesis Topics Selected for the FY 1993 Program; and (5) Index to Syntheses and Studies.
