In intelligent transportation systems, most of the research work has focused on lane change assistant systems. No existing work considers minimizing the disruption of traffic flow by maximizing the number of lane changes while eliminating the collisions. In this thesis, we develop qualitative and quantitative...
The growing uncertainty about oil prices and availability has made long-range transportation planning more challenging. Rather than relying on trend extrapolation, this study uses market mechanisms to evaluate key long-range transportation planning assumptions. Although the Washington Department of Transportation...
Commercial motor vehicle (CMV) enforcement efforts seek to make travel on public highways safer. CMV enforcement professionals secure compliance of CMV's with state laws regulating weight of commercial vehicles to protect state highways from unnecessary damage, and ensure payment of necessary registration...
Over time, road usage in western North Dakota has changed. Interstate, highway, and low-volume unpaved roads have been used with greater frequency because of increased agricultural production and a growing energy sector. This evolution is especially evident in a 17-county region where oil extraction...
A survey was conducted of small urban and rural transit agencies regarding their use of alternative fuels and hybrid vehicles. Responses were received from 115 transit providers across the country, including 31 that use biodiesel, eight that use E85, 10 that use compressed natural gas (CNG), four that...
The trucking industry is dynamic, and has been growing along with the economy. Many companies have come and gone, but many have been in business for many years. An increasing number of motor carriers can indicate a healthy industry and economy. While an increasing total number of motor carriers may indicate...
The North Dakota legislature recently passed a law to exempt the state's agricultural truck fleet from a requirement for rear-guard equipment as federally mandated large trucks. This analysis presents the public safety benefit-cost assessment of the device in terms of crash injury severity associated...
Because of the importance of safety, and the potential benefits for both the general public and the commercial vehicle industry of improving safety, the main goal of this project is to identify those commercial vehicle-related technologies that, through successful adoption, have had a positive impact...
This study provides information about the types of trucks owned and leased by farmers and how these trucks are utilized. It complements other studies of farm-to-market transportation in the Great Plains region, including a study by Baumel (1996) of grain movements in Iowa. The Baumel study provides detailed...
A testing facility for temporary longitudinal barriers was constructed at Colorado State University's Engineering Research Center which allows manufacturer's the opportunity to test their safety barriers prior to full-scale federal testing. This facility enables manufacturers to subject their products...
