Transcript of "Thompson Roadway Safety Data Program"

  1. 1. FHWARoadway Safety Data ProgramWebinar for FHWA Safety FieldFebruary 26, 20131
  2. 2. Benefits of Safety Data2• Use of integrated roadway, traffic, and crashdata in analysis can lead to more efficientuse of funds and improved safetyImprovedSafetyOutcomesBetterTargetedSafetyInvestmentsMoreInformedDecisionMakingImprovedDataCollection
  3. 3. MAP-21 - Safety Data Systems• States shall have in place a safety data systemsufficient to guide the Highway SafetyImprovement Program (HSIP) and StrategicHighway Safety Plan (SHSP) processes.3
  4. 4. MAP-21 Guidance• Types of roadways covered• Types of data included• Geolocation of safety data to a common highwaybasemap• Analysis and evaluation capabilities• Subset of Model Inventory of Roadway DataElements to be collected (referred to as the MIREFundamental Data Elements)4
  5. 5. System Requirements:Types of Roads• HSIP applies to all public roads• Data to be collected for all public roads, including:– State owned/maintained roads– Non State owned/maintained roads– Roads on tribal lands– Public roads on Federal lands5
  6. 6. System Requirements:Types of Data• Safety data to be collected includes:– Crash data– Roadway data– Traffic data– At RR grade crossings, highway and train traffic• Identify fatalities and serious injuries on all publicroads by location• Diverse data sets should be able to be linked orintegrated6
  7. 7. System Requirements:Geolocation of Safety Data• Crash, roadway and traffic data should be linkableby geolocation to a basemap that is inclusive of allpublic roads within a State.• August 7 2012, Memorandum on GeospatialNetwork for All Public Roads requires states toupdate LRS networks to include all public roads byJune 15, 20147
  8. 8. System Requirements:Analysis and Evaluation Capabilities• Ability to perform problem ID and countermeasure analysis• ID hazardous locations• Develop strategic and performance based safety goals• Advance State capabilities for data collection, analysis andintegration• Determine priorities and schedules for correction ofhazardous locations and conditions• Establish an evaluation process to assess results achievedby safety projects8
  9. 9. Subset of Model Inventory of RoadwayElements (MIRE) to be Collected• MAP-21 required the establishment of a subset ofMIRE elements that are useful for roadway safety• Subset enables jurisdictions to analyze crashexperience of roadway networks relative to theexpected average crash frequency given roadwayand traffic characteristics at specific locations9
  10. 10. Subset of Model Inventory of RoadwayElements (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 elements10
  11. 11. Subset of MIRE for Roads > 400 AADTRoadway Segment• Segment Identifier• Route Number• Route/street Name• Federal Aid/Route Type• Rural/Urban Designation• Surface Type• Begin Point SegmentDescriptor• End Point SegmentDescriptor• Segment Length• Direction of Inventory• Functional Class• Median Type• Access Control• One/Two-Way Operations• Number of through lanes• AADT• AADT Year• Type of GovernmentalOwnership11
  12. 12. Subset of MIRE for Roads > 400 AADTIntersection• Unique Junction Identifier• Location Identifier for Road 1Crossing Point• Location Identifier for Road 2Crossing Point• Intersection/JunctionGeometry• Intersection/Junction TrafficControl• AADT [for each IntersectionRoad]• AADT Year [for eachIntersecting Road]12

  15. 15. MAP-21 Eligible Safety Data Collection,Analysis, and Improvement Activities• “Highway safety improvement projects aredefined as strategies, activities and projects on apublic road that are consistent with a State’s SHSPand correct or improve a hazardous road locationor feature or address a highway safety problem.”• Collection, analysis and improvement of safetydata is specifically identified as an eligible projectwithin the definition of a HSIP15
  16. 16. Complementary Processes• MAP-21 specifies that State efforts to advancetheir capabilities for safety data collection,analysis and integration be conducted in amanner complements the Highway Safety Plan(NHTSA) and the Commercial Vehicle Safety Plan(FMCSA).• The State TRCC• The State’s Traffic Records Strategic Plan– MIRE FDE Implementation Plan16
  17. 17. State Safety Data Guidance Links• Guidance on State Safety Data Systemshttp://www.fhwa.dot.gov/map21/guidance/guidesafetydata.cfm• Question & Answer on State Safety Data Systemshttp://www.fhwa.dot.gov/map21/qandas/qassds.cfm17

Roadway Safety Data Program• Roadway Safety Data Capability Assessment• Model Inventory of Roadway Elements (MIRE)Management Information System (MIS)• Safety Data Technical Assistance Programs• Benefit-Cost Analysis Methodology for Safety DataInvestments• Highway Safety Manual (HSM) ImplementationSupport18http://safety.fhwa.dot.gov/rsdp/Contact:Ray Krammes
  19. 19. Roadway Safety Data CapabilitiesAssessment• Individual State assessments: State Action Plans• National assessment: Final Report• 4 peer exchanges:– Help States refine and implement Action Plans– Identify States’ priorities for national action19http://safety.fhwa.dot.gov/rsdp/Contact:Esther Strawder
  20. 20. States’ Priorities for National ActionData Collection• Noteworthy practices• Case studies• MAP-21 FDE guidance• Data on local roads• Technical assistance• Value of data improvementsData Analysis• Value of good analysis• Noteworthy practices• TrainingData Management• Guidance on dataintegration• Value of good datamanagement practices• Glossary of terms• Noteworthy practicesData Interoperability• Noteworthy TRCC practices• Value of linking data• Data “Focus States”• Training20
  21. 21. Model Inventory of Roadway Elements• MIRE Version 1.0: Listing & definition of elements• MIRE Management Information System– MIRE MIS structure– Performance measures for MIRE data– MIRE element collection mechanisms– MIRE intersection data extraction methods– Application of “collective information” to MIRE data21http://safety.fhwa.dot.gov/rsdp/Contact:Bob Pollack
