Management of Rural Expressways for Improved Safety and Operational Performance

Rural expressways are intended to provide many of the mobility and safety benefits of a freeway at far lower cost. Thousands of miles of rural expressways were planned and programmed around the United States and the conversion of two-lane highways to four-lane expressways is the fastest growing portion of the national highway systems with states like Missouri, Nebraska, and Texas having built and building hundreds of miles of expressways during the current decade. The Iowa DOT recently formed an interoffice expressway task force to develop a value engineering approach to improve the safety and operational performance of rural expressways. This project will support that team and help them satisfy some very specific objectives. Although the work for the task force will focus on Iowa, the report, technology transfer workshop, and other products will be applicable elsewhere.
