  6. “Road safety management is in transition. The transition is from action based on experience, intuition, judgment, and tradition, to action based on empirical evidence, science, and technology…” Ezra Hauer. (May 2005) HSM summary

  7. Safety Management Summary HSM Part B – Roadway Safety Management Process • Presents procedures and information useful in monitoring and reducing crash frequency on existing roadway networks • Six Steps in the Roadway Safety Management Process • Can be use sequentially as a process, or, • Can be selected and applied individually to respond to a specific problem or project

  8. Safety Management Summary Network Screening Chapter 4 • Review transportation network • Identify problem locations, road segments, corridors, etc. • Rank the sites based on potential for reducing crash frequency

  9. Safety Management Summary Diagnosis Chapter 5 • Diagnosis = evaluation to identify crash patterns using: • Past studies to identify known issues • Physical characteristics of the site • Driver behavior at the site • Other Information
