Demonstration of the United States Road Assessment (usRAP) as a Systematic Safety Tool for Two Lane Roadways and Highways in Kansas
Keyword(s):
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, system-wide 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.
