The National Cooprative Highway Research Program is a unique contract research effort designed to respond quickly and efficiently to the needs of State highway and transportation departments through the solution of the pressing transportation problems. Although the Transportation Research Board administers the Program, the research content is solely the prerogative of the American Association of State Highway and Transportation Officials and its member departments. The Program is one of applied (rather than basic) research, and every possible effort is made to help administrators and engineers put the findings to early use. Program policy ensures maximum exposure of the research while in progress in the hope that research results will, in fact, more quickly find their way into practice in the form of policies, procedures, specifications, and standards of State highway and transportation departments. This report describes current research in the following areas: pavements; economics; traffic operations and control; general materials; illumination and visibility; snow and ice control; traffic planning; forecast; bituminous materials; specifications, procedures, and practices; law; bridges; equipment; maintenance of way and structures; general design; roadside development; safety; concrete materials, finance; special projects; soils testing and instrumentation; vehicle barrier systems, soil properties; soil mechanics and foundations; and impact analysis.
