The 1990 Department of Transportation and Related Agencies Appropriation Act directed the Department of Transportation to prepare a report with the following objectives: update for the use of Congress a nationwide inventory of existing scenic byways; develop guidelines for the establishment of a National Scenic Byways Program, including recommended techniques for maintaining and enhancing the scenic, recreational, and historic qualities associated with each byway; conduct case studies of the economic impact of scenic byways on travel and tourism; and analyze potential safety consequences and environmental impacts associated with scenic byway designation. To respond directly to the first objective, the Federal Highway Administration developed a questionnaire in May 1990, to obtain information on Scenic Byways and byways programs. This report summarizes all four parts of the questionnaire.

Conference participants sought to identify gaps in the data and analytic tools needed to support economic analysis as related to transportation investment and to develop research proposals designed to fill those gaps. The opening day of the conference featured presentations by economists, transportation analysts, and policy makers on the theory and practice of economic analysis and its usefulness to decision makers. The second and third days of the conference revolved around participatory workshops. Six separate working groups deliberated over three questions: (1) What is the appropriate level of investment in transportation to encourage economic health? (2) How should projects be prioritized within a multimodal transportation program? (3) How much revenue is likely to flow from user charges, tolls, and other sources? At the conclusion of its deliberations, each working group developed a list of research proposals, which it then presented to the conference as a whole.

This synthesis will be of interest to state DOT construction, materials, statistical, specification, and inspection engineers; DOT research staff; pavement construction material suppliers; highway construction contractors; and civil engineering consulting firms, including field and laboratory materials testing personnel. The synthesis describes the state of the practice for defining and measuring variability in highway pavement construction. Data obtained from a review of the literature, a survey of state departments of transportation (DOTs), and discussions with selected state DOT personnel and private materials producers are presented. This report of the Transportation Research Board defines several measures of variability but concentrates on the use of standard deviation as the usual measure of variability. The synthesis updates reported typical variabilities found in materials and construction specifications. Also included are discussions of current research activities as related to variability, how variability can be used in the development of specification limits, the use of incentives and disincentives in specifications, and the need for additional information on the variability of several materials and construction processes.
