Filter by Keyword12 report(s) found with estimating in the keywords field Transportation access management is defined as systematic control of the design, spacing, operation, and locations of street connections, interchanges, driveways, and median openings on the roadway with the purpose of providing vehicle access while preserving the efficiency and safety of the entire transportation... The objective of this study is to develop a model for estimating demand for rural demand-response transit services for the general public. Lack of data for demand-response service characteristics and geographic coverage has limited the development of such models. This study developed two models for estimating... Estimating drilling locations plays an important role in forecasting truck trips derived by hydraulic fracturing oil development for long-range transportation planning. Predicting drilling locations among more than 7,000 oil drilling lands shows a random pattern with uncertainty. Twenty-year multi-period... This report examines the history of railroad cost analysis, examines some of the criticisms of current railroad costing methodologies, and presents some alternative methods for analyzing the costs of individual railroad movements. A software model was developed to estimate truck costs under different equipment configurations, input prices, and gross vehicle weights. The software was developed to obtain for many different configurations and trip characteristics. Important conclusions can be drawn from running simulations include... North Dakota's grain producers rely on an efficient rail system to move their products to export and domestic markets. A recent shift to larger grain hopper cars may threaten the viability of the state's light-density branch line network. This study simulates the impacts of handling larger rail cars... Differences that exist among truck configurations, trip and product characteristics, and input prices influence costs for individual owner/operators. Economic developers need truck cost estimates to compare transportation modes and accurately estimate transportation costs. Owner/operators and users of... This paper attempts to improve on the rail rate estimation employed by McFarland, while also measuring the impact of deregulation on rail profitability. 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 documents the installation and implementation of the Uniform Rail Costing System (URCS) at the Upper Great Plains Transportation Institute (UGPTI). |
