Practical tools for improving transportation safety are needed worldwide. It has been estimated that motor vehicle–related crashes account for more than 1 million fatalities each year, and the number of serious injuries far exceeds fatalities. Local and low-volume roads are significantly overrepresented in crash statistics. Globally, the road safety audit (RSA) concept has been recognized as an effective tool in identifying and reducing the crash potential of roadways when used to analyze the safety aspects of project plans and designs before completion. In the local rural road arena, many safety issues are associated with existing roadway networks. Many of these networks have developed over time with little or no planning or design. There is a critical need for a practical tool that focuses on the safety of the existing as-built local road network. The RSA review (RSAR) process has been developed for this purpose, giving specific recognition to the functionality of the road being evaluated for safety issues. Significant numbers of safety improvements are needed, and practical approaches to address these needs are crucial. The RSAR tool has the potential to be particularly beneficial to local governments in systematically addressing safety deficiencies on existing rural road networks. In addition, it is a proactive safety tool that has the potential to protect agencies from tort liability since it establishes a record of the organization’s safety agenda. An RSAR methodology that can be adapted by local agencies is presented. A case study illustrating the application of this process is included. Also highlighted is a local rural training program that has been presented in several states for county applications. The focus is on U.S. county applications, but it is recognized that the process has utility for other agencies and has application in other countries. The necessity for training as a key component in the development of a sustainable safety program is emphasized.
A prototype safety improvement program (SIP) developed specifically for unpaved roads is presented. The combination of high mileage, low traffic volume, and limited budgets makes it difficult for local agencies to adopt traditional SIPs. The presented SIP for unpaved roads is economically and procedurally appropriate for local road agencies. It provides a systematic means of prioritizing road sections for safety analysis and identifying safety improvement needs. One of the many unique features of the program is its “partnering” approach of involving public road users in the safety improvement process. Results of case studies that validate the procedure are included.
The need of local road managers to have a readily accessible reference guide for identifying deficiencies and improving safety on low-volume roads has prompted the development of a field guide for unpaved rural roads. Technical resources are available to evaluate the various aspects of a low-volume road. However, the resources are in numerous publications and not in a single, easy-to-use document. The concept of the field guide is to provide a single reference to assist rural road managers in making on-site evaluations of specific roadway deficiencies. Critical safety issues and unpaved rural road responsibilities vary throughout the United States. A national focus group was used to recognize this variability. A modified Delphi survey procedure was used to facilitate focus group input and review the project. The Wyoming Technology Transfer Center, in cooperation with the FHWA Local Technical Assistance Program, was responsible for development of the guide. Reviewed are the steps and considerations taken in the development of the guide. Developmental techniques, such as input from a national focus group of transportation professionals, were used to successfully complete this project. The methodologies used to develop this guide are applicable and potentially useful for completing other transportation projects worldwide.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
