HIGHWAY SAFETY MANUAL (HSM)
The first edition of the American Association of State Highway Transportation Officials (AASHTO) HSM was published in 2010. The HSM provides detailed processes for consistently quantifying the safety impacts of proposed improvements. The Nevada Project Safety Process (PSP) is a guide for the incorporating these processes into all projects in Nevada. The purpose of the PSP is to establish a consistent process of quantifying the expected crash impacts for future transportation improvements based on the HSM to the extent practicable. This process is applicable to all projects that impact roadway geometry, not just safety projects.
