Demonstration of the United States Road Assessment (usRAP) as a Systematic Safety Tool for Two Lane Roadways and Highways in Kansas

The United States Road Assessment Program (usRAP) is a systematic tool that determines areas of risk based on roadways characteristics. To determine the effectiveness of the usRAP tool, three rural two-lane corridors, a US highway, a Kansas highway, and a rural secondary road, were selected for this study. Data collection for the usRAP software included manual speed data collection, systemwide centerline miles and crashes, crash costs, countermeasure costs, and manual roadway coding data every 100 m. The usRAP software evaluated and developed a star rating and a Safer Roads Investment Plan for each corridor.
