Implementation Assistance Program – The Concept to Countermeasure Project
Through the Federal Highway Administration/American Association of State Highway and Transportation Officials (FHWA/AASHTO) Implementation Assistance Program (IAP), results from the second Strategic Highway Research Program’s (SHRP2) Naturalistic Driving Study (NDS) and Roadway Information Database (RID) projects are being made available to State departments of transportation (DOTs) interested in analyzing these data to identify crash causation factors and to develop effective countermeasures, such as improved road designs or public safety campaigns, that will address their common safety concerns.
In August 2014, FHWA and AASHTO announced that 10 States are participating in a proof of concept effort offered through the IAP project, titled: Concept to Countermeasure – Research to Deployment Using the SHRP2 Safety Data. Approximately $3 million in financial and technical assistance is being made available to conduct research on 11 high priority topic areas. Participants of the IAP have agreed not only to research a topic using SHRP2 NDS and RID data, but also to actively pilot and promote any promising countermeasures that are identified by their research. A primary – but not the only – goal is national adoption of new countermeasures. States, partnered with researchers, will manage the research, implement findings, and deliver authorized research results.
A Three-phased Approach
This IAP project is designed as a three-phased process. In phase 1, the participating State DOTs and their research partners will use a reduced set of NDS and RID data to demonstrate that their concept is viable, and that a full analysis with a larger dataset can answer the research question.
At the end of phase 1, the work will be presented and reviewed by FHWA and the AASHTO SHRP2 Safety Task Force to determine whether the results are promising enough to move to phase 2. If phase 2 produces meaningful results that are likely to lead to an implementable countermeasure then FHWA could provide additional financial or technical support for phase 3, which would address implementing the countermeasure. Implementation would not include additional research; instead, implementation in phase 3 could include engineering or other support to update national manuals or policies, or strategies to incorporate the countermeasure and endorse it for national adoption. Phase 3 might also include pilot testing a developed safety countermeasure in the field, implementing new public outreach efforts, or using other measures to improve highway safety.
The 10 State DOTs that were selected to begin research in January 2015 using the NDS and RID data received $100,000 for each proposal. The States will initially use a sample dataset and will report on their findings by September 2015.
The following table details the topics for the proof of concept and the State DOTs that will be involved in the project.
