  1. Highway Safety Improvement Program Data Requirements NACE Annual Conference April 23, 2013

  2. Highway Safety Improvement Program • Strategic safety planning • Data-driven roadway safety management process • Infrastructure-related safety improvements • Federally-funded, state administered

  3. Relationship of HSIP Programs MAP-21

  4. Strategic Highway Safety Plans (SHSPs) • Data-driven statewide plan • Establishes a common vision, mission and goals to save lives on all public roads • Identifies a State’s key transportation safety needs and guides investment decisions • Prioritizes strategies with the greatest potential to reduce fatalities and serious injuries • Developed in collaboration with a broad range of stakeholders • Multidisciplinary addressing 4 Es of Safety • Determines measurable performance targets Vision Innovation

  5. State Highway Safety Improvement Program HSIP Planning Data/Design Standards Problem Identification Countermeasure Identification Feedback Project Prioritization HSIP Project List STIP Implementation Schedule and Implement projects Evaluation Determine Effects of Highway Safety Improvements Site Analysis Approach Systemic Approach

  6. Benefits of Safety Data • Use of integrated roadway, traffic, and crash data in analysis can lead to more efficient use of funds and improved safety

  7. MAP-21 on Safety Data Systems • States shall have in place a safety data system sufficient to guide the Highway Safety Improvement Program (HSIP) and Strategic Highway Safety Plan (SHSP) processes, including: • Safety problem identification and countermeasure analysis • Identification of hazardous locations • Strategic and performance-based goal setting • Advancing capabilities for safety data collection, analysis and integration

  8. System Requirements – Roads Coverage • HSIP applies to all public roads • Data to be collected from: - State owned/maintained roads - Non State owned/maintained roads - Roads on tribal lands - Public roads on Federal lands

  9. System Requirements – Types of Data • Safety data are used to identify hazardous locations, sections and elements on all public roads by location • Safety data to be collected for all road users includes: • Crash data • Roadway data • Traffic data • At RR grade crossings, highway and train traffic • Diverse data sets should be able to be linked or integrated

  10. System Requirements – Geolocation of Safety Data • Crash, roadway and traffic data should be linkable by geolocation to a basemap that is inclusive of all public roads within a State. • August 7 2012, Memorandum on Geospatial Network for All Public Roads requires states to update LRS networks to include all public roads by June 15, 2014

  11. Subset of Model Inventory of Roadway Elements (MIRE) to be Collected • MAP-21 required the establishment of a subset of MIRE elements that are useful for roadway safety • Subset enables jurisdictions to analyze crash experience of roadway networks relative to the expected average crash frequency given roadway and traffic characteristics at specific locations

  12. Subset of Model Inventory of Roadway Elements (MIRE) to be Collected - Cont • For roads > 400 AADT subset includes: • Road segment elements • Intersection elements • Interchange/ramp elements • For roads < 400 AADT subset includes: • Road segment elements • Intersection elements

  13. MAP-21 Eligible Safety Data Collection, Analysis, and Improvement Activities • “Highway safety improvement projects are defined as strategies, activities and projects on a public road that are consistent with a State’s SHSP and correct or improve a hazardous road location or feature or address a highway safety problem.” • Collection, analysis and improvement of safety data is specifically identified as an eligible project within the definition of a HSIP

  14. Implications for State Safety Data Systems • Not collecting data for data’s sake • Optimal safety investment decisions • Improvement in safety programs through improved analysis methods (e.g., HSM) • More effective deployment of safety resources • Follow-up rulemaking to further address safety data requirements

  15. State Safety Data Guidance Links • Guidance on State Safety Data Systems http://www.fhwa.dot.gov/map21/guidance/guidesafetydata.cfm • Question & Answer on State Safety Data Systems http://www.fhwa.dot.gov/map21/qandas/qassds.cfm

  16. Benefits • Target areas of greatest need • Systematic and repeatable process • Prioritized investments • Defensible decisions • Lives saved!!!

  17. Resources • HSIP Training (NHI) • HSIP Overview • SHSP Development • SHSP Implementation • HSIP Project ID • HSIP Project Evaluation • Systemic Safety Project Selection Tool (Draft) • Safety Peer-to-Peer Program
