Filter by Keyword68 report(s) found with roads in the keywords field This paper examines the effectiveness of applying chip seal friction courses in reducing accidents on low volume, rural roads. Chip sealing data from District 3 of the Utah Department of Transportation were used to examine accident rates before and after applying chip seal. Although accident rates generally... The overall purpose of this report is to evaluate the perspectives and practice of economic and safety regulation of local and regional short line railroads. Specific objectives are to: (1) review the dynamics of the short line railroad spin-off movement in the United States and the Mountain-Plains Consortium... This report covers the first year of a two-year study of unpaved roads. Maintenance and reconstruction models of unpaved roads are reviewed. These models are based upon empirical and mechanistic methods, and they have the objective of evaluating deterioration, roughness propagation parameters, scraping... The goals of this study were to depict the continuing educational needs of Region VIII state transportation departments, to devise alternative methods of educational delivery, and to identify and overcome institutional and technological barriers. Surveys of Wyoming and North Dakota transportation department... This study examines consolidation of road services by local governments, and explores the optimal mix of roads for rural counties. A methodology for measuring economies in the provision of local road services is presented. This methodology is unique in two ways; 1) it better accounts for relevant variables... The goal of this research is to estimate productivity gains and cost savings in the railroad industry since 1978. Further, prior work was extended by separating output and size variables into measures of high and low density output and miles of track. For purposes of comparison, a translog cost function... This report reviews the state-of-the-practice in low-volume road pavement design. The factors which dictate pavement design are discussed in terms of construction materials, environment, and traffic. Eight different design procedures are presented and discussed. These include the 1972 and 1986 AASHTO... The overall objective was to determine the extent that economies of size and density are available to short line railroads. Size economies are limited for short line railroads. For example, doubling the size of the network (from 56 to 129 miles) decreases costs by only 6.9 percent. The elasticity of... |
