Filter by Keyword61 report(s) found with highway safety in the keywords field The goal of this study was to contribute localized information for decision-making to allocate traffic safety resources in the Northern Rocky Mountain Region states of Montana, North Dakota, South Dakota, and Wyoming. The rural nature of the region differentiates its driving environment from other more... 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... A study of collisions occurring at intersections along State routes in Utah was conducted. The number of crashes, the crash severity score and, for selected locations, the crash rate were determined and "ranked" for intersections within the Utah Department of Transportation's Region 1, Region 2, Region... 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... The study focuses on ascertaining information on user willingness-to-pay and their perceptions of funding for improving gravel roads which support freight transportation service in rural areas. The research considers safety, road type, and maintenance valuation for both gravel and paved road surfaces.... Congestion in Salt Lake City is showing an increasing trend and, as congestion reaches higher levels, benefits of the HOV lanes will also increase. It needs to be determined whether the Salt Lake Valley HOV lanes are performing effectively in terms of travel time benefits, safety and the ability to carry... 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... A variety of portable safety and security barriers for directing traffic (public events, sports facilities, etc.), and securing private and public locations against access (court houses, schools, etc.) have been developed. Some higher capacity systems have been developed for use on and around high speed... This report presents results of an investigation into the practice and legal issues of Road Safety Audits and Road Safety Audit Reviews (RSAs and RSARs). These safety analysis approaches focus on identifying safety issues of proposed projects (RSA) and existing roadways (RSAR). In the United States... This project developed a simple and cost-effective rural RSAR program. The RSAR program was developed to identify critical safety issues and to assess the level of auditor expertise needed. The specific issues of needed safety improvements and the urgency of implementing these improvements have been... |
