1 1 Element 1: The Systemic Safety Project Selection Process Element 1: 4-Step 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. 2 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. 3 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. 4 Element 1, Step 3: Select Countermeasures

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

6 Element 1: Step 3, Task 1 Assemble 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 6

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 7

8 Element 1: Step 3, Task 1 Assemble Comprehensive List Process: 1.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 8

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. 9 Element 1: Step 3, Task 1

10 Road Departure Strategies NCHRP Report 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. – Countermeasures that Work – Enforcement and education countermeasures 11 Element 1: Step 3, Task 1

12 Element 1: Step 3, Task 2 Evaluate & 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 12

13 Element 1: Step 3, Task 2 Evaluate & 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 13

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

16 Element 1: Step 3, Task 3 Select Countermeasures for Deployment Process: 1.Select a few countermeasures (from the lists created in Step 3, Task 2) for each target crash type. 2.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 16
