Filter by Keyword41 report(s) found with forecasting in the keywords field In this study, the cohort-component method of population projection is used to project changes in the size of various groups at five-year intervals from 2005 to 2025 for each of North Dakota's 53 counties. The populations of interest in the study, seniors, the disabled, students age 5 to 19, and households... This report identifies several factors critical to the success of short line rail roads. Success was measured and analyzed by looking at variables related to traffic volume, backhaul traffic, reliance on industries and/or commodities, number of shippers, flexibility of labor, track conditions, management... Voluntary turnover rates among truckload carriers are extremely high, ranging from 50 to more than 100 percent annually. These high turnover rates result in elevated costs for carriers in terms of recruitment and training as well as costs associated with reduced productivity and decreased customer satisfaction... Fluctuation in temperatures significantly affects pavement stability and the selection of asphalt grading to be used in pavements. Ability to accurately predict the asphalt pavement temperature at different depths and horizontal locations based on ambient air temperatures will greatly help pavement engineers... The objective of this report is to develop a profile of the U.S. containerized grain and oilseed export industry, including marketing activities, future expectations, information needs, and business practices. This report forms Phase I in a proposed two-phase analysis of the grain container industry.... 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 feasibility of using the Georgia Loaded-Wheel Tester (GLWT) to predict rutting in the laboratory was investigated in this research. This research was performed in two phases. The first phase consisted of modifying the GLWT to handle 15.2 cm (6 in) cores, developing a laboratory compaction procedure... In this research the feasibility of using the Georgia Loaded-Wheel Tester (GLWT) to predict rutting in the laboratory was investigated. The study consisted of modifying the GLWT to handle 15.2 cm (6-in.) cores, obtaining asphalt pavement cores from several test sites throughout Wyoming, collecting rut... The primary objective of this research was to establish statistically valid mathematical models that can explain the variations in accidents as a function of geometric variables. Engineers and planners will be able to use these models to examine the sensitivity of accident rates to any of the independent... Transit service is playing an increasingly vital role in maintaining and improving mobility and economic well-being of rural populations in the North Central region. At the same time that transit service is increasing in importance, higher operating expenses and reduced federal subsidies are making management... |
