Filter by Keyword17 report(s) found with size in the keywords field This study provides a theoretical evaluation of Transit Signal Priority (TSP) strategies in small-medium size areas to alleviate missed connections, enhance service, and attract more transit riders. Several scenarios are evaluated, involving two TSP strategies; existing and reduced bus headways; and... The study demonstrated that short lines could achieve greater cost savings if they were to increase their density (revenue ton miles per mile) and their size (mile of road). Size is an important criterion that a short line must examine when evaluating the purchase of a new section of track. However... Public concern about hazardous materials, such as agricultural fertilizers, has steadily increased. Thus, North Dakota created Recommended Management Practices for The Primary and Secondary Containment of Fertilizers (RMP).
This study attempted to determine how compliance with RMP guidelines affects... This project has three primary objectives: 1) to provide an analysis of the current trucking industry; 2) to determine the cost of current weight and safety enforcement activities; and 3) to evaluate the benefits to state regulatory agencies of enhanced regulatory efficiency. The primary objective of this study was to investigate the effects of freeze-thaw conditioning and overloading on the resilient modulus (Mr) of subgrade soils susceptible to frost penetration. The Mr values of conditioned samples were compared to unconditioned samples. All Mr values were determined in... 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... This report discusses the maximum vehicle weights and length limits of different truck sizes. |
