Presentation Transcript

  1. Intervention Tools Demonstrate the use of tools, such as statistical modeling, the Australian model, the Haddon Matrix, engineering studies, and road safety audits or assessments, for identifying effective interventions.

  2. Major Topics • Statistical Models • Engineering Studies • Road Safety Audits • The Australian Safe Systems Approach • The Haddon Matrix

  3. Models for Identifying Sites The identification and examination of well chosen sites will yield safety improvements…

  4. Example Think about it …

  5. Engineering Studies Think about it … • Step 1: Examine the Crash Data • Step 2: Conduct a Field Study • Step 3: Identify Countermeasures • Step 4: Prioritize Countermeasures • Step 5: Implement the Countermeasures • Step 6: Evaluate the countermeasure impact

  6. Road Safety Audits • A formal examination with a structured process; • Conducted independently by professionals who are not currently involved with the project; • Completed by a team of qualified professionals representing appropriate disciplines; • Focuses solely on safety issues; and • Examines the transportation site with respect to all potential road users.

  7. The Australian Model Think about it … The Safe Systems Approach

  8. The Haddon Matrix • Crash Time • Pre Crash • Crash • Post Crash • Other Factors • Human • Vehicle • Roadway • Environmental

  9. The Haddon Matrix (cont.) Note: Evans thinks the matrix places too much emphasis on the crash, and that “Pre-crash” has usually meant the seconds before the crash. However, that view probably pertains to this matrix without the fourth column (early Haddon matrix had only the first 3 columns). http://www.tsc.berkeley.edu/newsletter/winter05-06/haddon.html

  10. Review • Statistical Models • Engineering Studies • Road Safety Audits • The Australian Safe Systems Approach • The Haddon Matrix
