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 report contains a brief description of Intelligent Transportation Systems (ITS) and ITS technologies for Commercial Vehicle Operations (ITS/CVO). Second, it discusses previous literature regarding benefits of ITS/CVO for motor carriers, as well as managing the change due to technology. In addition...

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...

This study aims to evaluate the use of the Road Safety Audit Program, by a local rural road jurisdiction, to avoid tort liability while still improving the safety of its road system. The study will provide how the RSA might be accepted within the current legal framework and will provide guidelines for...

While SafeStat was designed to prioritize carriers for monitoring and compliance reviews, the ISS was designed to prioritize carriers for roadside inspection. However, both algorithms use similar data to define a relatively unsafe carrier. It would be beneficial if there could be one uniform motor carrier...

This study was conducted due to concerns related to pedestrian/vehicle conflicts in the area of the intersection of University Dr. and Administration Ave. The intersection is currently controlled by stop signs on the minor approaches (Administration Ave., the NDSU Station Post Office, and the Alumni...

In this study the researchers examined the effect of pavement shoulders on the safety and structural strength of highways in Wyoming. The costs of adding shoulders to various types of highways also was examined. The study consisted of selecting representative highway sections, collecting accident data...

This report documents the findings of the National Peer Exchange on Educational and Technical Assistance to Motor Carriers and Commercial Vehicle Drivers (ETA). The report identifies ETA best practices observed during site visits to the participating states and trucking companies.
