View AllThis workforce assessment is only the first step in developing a strategic human capital plan for NDDOT. The external and internal forces affecting the availability of the future workforce have been documented for a specific period of time. NDDOT has begun to develop several programs including succession... Although transportation plays a role in economic development, it often is assumed to be an inert factor because of data voids or under assumptions. This research offers estimates of the relative quality of freight and business transport service resources available to non-metropolitan cities across the... Investigations into the effects Z-spiking with fiber reinforced polymer (FRP) rods have on the flexural stiffness and repair of deteriorated railroad crossties were conducted. These tests were conducted to provide a pilot study for an ultimate goal of repairing full-scale bridges. This report presents... A preliminary study modeling the nonlinear behavior of long, slender wooden members was conducted at Colorado State University for the purpose of their use in inexpensive, destroyable crash barriers. This preliminary study compared the results of physical test data, published exact solutions, and the... This research project, "Evaluating and Improving Pedestrian Safety in Utah," was initiated in December 2000. Two interim reports have been prepared thus far, including Facilitation of Pedestrian Crossings in 28 States and Literature Review of Pedestrian Safety Measures (Cottrell 2001) and Literature... The main objective of this research was to quantify the differences and similarities among Quality Control/ Quality Assurance (QC/QA) programs for three state highway agencies. By measuring these differences, conclusions were drawn as to which state was achieving the best results with their QC/QA program.... This paper reports on a two-year study evaluating HOV lane performance. The analysis assesses the freeway operations before the HOV lanes opened with continued assessment throughout the first year of operation. It looks at automatic data from traffic monitoring stations and manual data from roadside... The main objective of this study was to investigate the effect of the addition of a coal combustion remnant called bottom ash into asphalt mixes. The intent was to determine if mixes prepared with bottom ash showed degradation of desirable performance measures when compared to control mixes. This was... This report describes a research project conducted at Colorado State University to evaluate the effect of road dust suppression on unpaved road maintenance schemes. A field-based method was used to measure the effect of road soil physical characteristics on the effectiveness of some of the commonly... The study surveyed small to medium size agencies, ranging from 700 to 17,000 trips per month. The results clearly indicated that all of the agencies in this range benefited from low cost computer software for the purposes of making trip reservations, scheduling trips, dispatching trips, record keeping... |
