  1. MIRE FDEsThe Clock is Ticking TRF – Austin, TX Robert Pollack Nancy Lefler August 5, 2019

  2. MIRE Background

  3. MIRE – Model Inventory of Roadway Elements • Recommended listing of roadway and traffic elements critical to safety management • Data dictionary – definition, attributes, etc. • MIRE 1.0 released in 2010 • MIRE 2.0 released in 2017 • https://safety.fhwa.dot.gov/rsdp/downloads/fhwasa17048.pdf

  4. Why MIRE? • Using roadway/traffic data merged with crash data enables users to: • Develop relationships of safety to roadway features and user exposure. • Better identify location and characteristics of crashes. • Better determine appropriate countermeasures and strategies. • Evaluate the effectiveness of safety treatments.

  5. How to Use MIRE States should take what is useful in MIRE and apply it in a way that helps improve their inventory, and ultimately lead to better data-driven decision making.

  6. How to Use MIRE • Meeting the FDE Requirement • Improving overall roadway data inventory • Improving or adding a category of elements • Improving single elements

  7. MIRE 2.0 Revisions • General structure • Elements • Roadway segment data • Roadway alignment data • Roadway junction data • https://safety.fhwa.dot.gov/rsdp/downloads/fhwasa17048.pdf

  8. General Structure MIRE 1.0 MIRE 2.0 Divided into six data categories: Segment Intersection Intersection Leg Interchange/Ramp Horizontal Curve Vertical Grade

  9. Elements • Updated to meet HPMS/Fed datasets • Updated to reflect evolving operational and design practices • Added new elements

  10. MIRE FDEs

  11. Fixing America's Surface Transportation Act (FAST Act) Guidance on State Safety Data Systems https://safety.fhwa.dot.gov/legislationandpolicy/fast/ssds_guidance.cfm • State safety data capabilities required to satisfy the HSIP requirements • Essentially rely on data driven decision safety analysis for HSIP program direction • The safety data collection, integration, improvement, and analysis activities eligible for HSIP funding • Develop a subset of MIRE data elements useful for the inventory of roadway safety • Bottom line result – Significant reductions in fatalities and serious injuries on ALL public roads

  12. Highway Safety Improvement Program State Safety Data System Capabilities Priorities And Project Selection Safety Data MIRE FDE Roadway Data System Safety Analysis and Evaluation All Public Roads Common Base Map Crash Data System Traffic Data System

  13. Safety Management Methods

  14. MIRE FDEs Requirements • Table 1, non-local paved roads, 37 elements, 19 HPMS • Table 2, Local Paved Roads, 9 elements, 8 HPMS • Table 3, Unpaved Roads, 5 elements, 4 HPMS https://safety.fhwa.dot.gov/legislationandpolicy/fast/ssds_guidance.cfm The FAST Act adds the provision that States may elect not to collect the MIRE FDE on gravel or otherwise unpaved roads as long as they meet two conditions: A. The States do not use HSIP funds on any unpaved road for which they do not collect the MIRE FDEs [23 U.S.C. 148(k)(1)(A)]; and B. The States demonstrate having consulted with affected Indian tribes before ceasing to collect data on roads included in the National Tribal Transportation Facility Inventory [23 U.S.C. 148(k)(1)(B)].

  15. How were the MIRE FDE Chosen?FDEs Should Enable Agencies to: • Define roadway segments, intersections and interchanges/ramps • Delineate basic information needed to characterize the roadway type and exposure • Identify governmental ownership and functional classification consistent with the HSIP reporting requirements

  17. MIRE FDE Critical Dates • July 1, 2017 – Incorporate specific quantifiable and measurable anticipated improvements that prioritizes the collection of MIRE FDE into the Traffic Records Strategic Plan • September 30, 2026 – Access to a complete collection of MIRE FDE on all public roads

  18. MIRE FDE Follow-up • Each year states will be asked to report progress towards meeting the MIRE FDE requirements as part of their annual HSIP update due each August • States may contact FHWA Division Offices or the Office of Safety with any questions pertaining to the MIRE FDEs

  19. FDE Status Update

  20. Current Status of State FDE Process • Office of Safety has begun a process to ascertain the current status of State progress toward compliance with FDE requirement • Will arrange sessions with Division Office on how the State is progressing toward FDE compliance • Identify challenges and opportunities for MIRE FDE improvement

  21. FHWA Resources

  22. Technical Assistance • Roadway Data Improvement Program (RDIP) • Safety Data and Analysis Technical Assistance • Local Data Integration Technical Assistance • Safety Data Management and Governance Technical Assistance • Office of Safety Technical Assistance Program (the Peer-to-Peer Program)
