  1. Element 1: 4-Step Project Selection Process Element 1: The Systemic Safety Project Selection Process

  2. Objective • Identify a few low-cost, effective countermeasures for project development at candidate locations. • “Few” = Consider more than one low-cost countermeasure to provide flexibility for various conditions Suggestion • Have 1 or 2 higher cost countermeasures for special circumstances. Element 1, Step 3: Select Countermeasures

  3. Outcome • Short list of effective, low-cost countermeasures for focus crash type(s) and focus facilities. • Greater understanding of pros and cons of each countermeasure. Element 1, Step 3: Select Countermeasures

  4. Data Needs • No crash, roadway, or other specific data is utilized in this step of the process. • Do need an understanding of agency policies and practices, including how well a countermeasure has worked locally. Element 1, Step 3: Select Countermeasures

  5. Element 1: Step 3 Element 1, Step 3: Select Countermeasures

  6. Element 1: Step 3, Task 1Assemble Comprehensive List Purpose: • Develop a comprehensive list of safety countermeasures that could be appropriate for systemic deployment to target the focus crash type(s) on the prioritized network elements. Element 1: Step 3, Task 1

  7. Element 1: Step 3, Task 1 Assemble Comprehensive List Resources: • NCHRP Report 500 Series • Highway Safety Manual • FHWA’s Crash Modification Factors Clearinghouse • FHWA illustrated guide sheets for intersection strategies • FHWA Office of Safety website • State or regional SHSPs • NHTSA’s Countermeasures that Work • Other applicable safety plans • Published research documenting the effectiveness of strategies Element 1: Step 3, Task 1

  8. Element 1: Step 3, Task 1Assemble Comprehensive List Process: • Consult resources to generate lists of countermeasures that addresses each focus crash type(s). Suggestion: • Place emphasis on low-cost, easy to implement countermeasures with proven effectiveness. • Select countermeasures appropriate for focus facility type Element 1: Step 3, Task 1

  9. Safety Strategies Overview NCHRP Report 500 • A series of guides to assist state and local agencies in reducing injuries and fatalities in targeted emphasis areas • The guides correspond to the emphasis areas outlined in the AASHTO Strategic Highway Safety Plan. • Each guide includes a brief introduction, a general description of the problem, the strategies/ countermeasures to address the problem, and a model implementation process. Element 1: Step 3, Task 1

  10. Road Departure Strategies NCHRP Report 500 Element 1: Step 3, Task 1

  11. Other Resources– More Current – • HSM, Part D – Hundreds of countermeasures with CMFs. • CMF Clearinghouse – Searchable database updated regularly. • www.cmfclearinghouse.org • Countermeasures that Work – Enforcement and education countermeasures Element 1: Step 3, Task 1

  12. Element 1: Step 3, Task 2Evaluate & Screen Countermeasures Purpose: • Evaluate and screen the comprehensive list of countermeasures • Documented effectiveness (at reducing the target crash types) • Implementation and maintenance costs • Consistency with the agency’s policies, practices, and experiences. Element 1: Step 3, Task 2

  13. Element 1: Step 3, Task 2Evaluate & Screen Countermeasures Resources: • Highway Safety Manual • FHWA’s Crash Modification Factors Clearinghouse • Published research documenting the effectiveness of strategies Element 1: Step 3, Task 2

  14. Element 1: Step 3, Task 2Evaluate & Screen Countermeasures Process: • Review resources to select the countermeasure(s) with the greatest potential to address the priority crash type(s) across the prioritized locations. • Eliminate the countermeasures with the low potential to address priority crash type(s), not consistent with agency practices, or not practical to implement/ maintain. • Finalize list of countermeasures. Option • Stakeholder input from multi-agency & multi-discipline workshop. Element 1: Step 3, Task 2

  15. Minnesota Rural County - Workshops Voting Results Element 1: Step 3, Task 2

  16. Element 1: Step 3, Task 3 Select Countermeasures for Deployment Process: • Select a few countermeasures (from the lists created in Step 3, Task 2) for each target crash type. • Assemble countermeasures to create short list of strategies for each target crash type. Include enough countermeasures to provide a measure of flexibility. Element 1: Step 3, Task 3

  17. Run-Off Road Countermeasures Element 1: Step 3, Task 3

  18. Intersection Countermeasures Dynamic Warning Signs Change Intersection Type Improve Sight Distance Street Lighting Enhanced Signing and Delineation Indirect Turns Element 1: Step 3, Task 3

  19. Pedestrian Countermeasures Countdown Timers and Advanced Pedestrian Intervals Curb Extensions and Medians Element 1: Step 3, Task 3
