  2. Overview • A Crash Analysis Continuum • Users/Customers • Needs/Wants & Resources • Examples

  3. A Crash Analysis Continuum SICL/Comparables National Research CMaT/IMAT Raw Data SAVER WWW CARE ITSDS CODES Annual Requests Special Requests Less User Interaction More

  4. System Interconnectivity

  5. Users/Customers • Wide Spectrum!!! • Federal • State • Local

  6. Users/Customers - Federal • FHWA • FMCSA • NHTSA • BTS • Federal Research – NCHRP & Pooled • 4  3-lane conversions • Transverse Rumble Strips • Lane Departure – Shoulder Rumble Strips • Bridge Rail

  7. Users/Customers - State • Iowa DOT • Highway – TAS, Maintenance, Planning, etc. • MVD • DPS/GTSB • DPH • DNR • Legislators • Other states

  8. Users/Customers - Local • RPA/MPO • Counties • engineering mostly • Cities • engineering • enforcement • Consultants • Citizens/Coalitions • Lawyers • Media

  9. Needs/Wants • Recall Crash Analysis Continuum • Needs vs. Wants • Determine the difference • Provide former • Strive to provide latter, if possible • Avoid overkill

  10. Needs/Wants - WWW • Common requests • Public interest information/reports • Broad data/analyses • Safety Improvement Candidate Locations (SICL) • Comparables • County maps on various topics (e.g., deer) • Crash Facts • Driver Facts • Anything pre-preparable of interest • http://www.dot.state.ia.us/crashanalysis/ • http://www.dot.state.ia.us/mvd/ods/ • http://www.dps.state.ia.us/gtsb/ • http://www.ctre.iastate.edu/itsds/

  11. Needs/Wants – Annual Requests • Workzone • Bicycle/Pedestrian • GTSB Problem ID • Animal/Deer • Farm Vehicle • Tall corn • Key Emphasis Areas

  12. Needs/Wants – SICL/Comparables • Top 200 • County SICL – top 25+ • City SICL – top 25+ • Avg. Segment Rates/Densities • Avg. Intersection Rates/Densities • City/County Profiles

  13. Needs/Wants – ITSDS • GTSB/DOT partnership • Corridor enforcement programs • Seatbelt use • BAC • Speeding • Fatal/Major Injury maps • Driver age • Site-specific • Variety and Flexibility

  14. Needs/Wants – National Research • Transverse Rumble Strips • 4  3-lane Conversions • Lane Departure (SVROR & MVCC/CM) • Bridge Rail • Low-Cost Safety Improvement • US RAP • Numerous others…

  15. Needs/Wants – Special Requests • Planning Study – 5-year plan • Older drivers • Younger drivers • Reauthorization impacts • CHSP • STRAC

  16. Needs/Wants – CMaT/IMAT • User-friendly tool • Available free to local agencies for quick analysis of limited data sets • Can be used with Iowa crash data or other data

  17. Needs/Wants – SAVER • ESRI ArcView 3.2 GIS-based • Freely distributed project/extension (but requires an ESRI ArcView license) • Intended for more sophisticated users • Allows user to add own additional layers • Produces tabular reports and maps • Future  GeoMedia SAVER • SAVER • CMaT-like • Diagram Magic

  18. Needs/Wants • CODES • Raw Data

  19. Resources – Other Services Statewide Programs • Federal Hazard Elimination Program • Highway Safety Management System (SMS) • Data-Driven Highway Safety Program • Safety Conscious Planning • 3R Roadway Safety Audits Local Assistance Programs • State Traffic Safety Improvement Programs (TSIP) • Traffic Engineering Assistance Program (TEAP) • Safety Data Products • Crash Data Analysis Tools • Iowa Traffic Safety Data Services (ITSDS) • Traffic & Safety Engineering Forum • Small town signing program

  23. Targeted Enforcement1995-1999 Rural Alcohol-Related Crashes Corridors ranked by Frequency

  24. School-AgePedestrianCrashes City of Des Moines 1995 to 1999 Ages 5 to 19 August 15 to June 15 Monday to Friday 7:00 a.m. to 5:00 p.m. Schools Data Use Middle Schools

  25. Two Lane Safety CorridorsRural Two-Lane Primary Road Fatalities and Major Injuries (District 6 1998-2000) DOTData Use 25 unlocated injury severities not represented. (2 Fatal, 23 Major Injuries) Disclaimer: The Center for Transportation Research and Education presents these data as preliminary.

  26. Target Corridors with high numbers of Single-Vehicle, Run-off-the-Road Crashes on 2-Lane Highways (example District 5)

  27. Primary Highway Curve Crashes • Statewide average = 1.1 / MVM (avg radius = 2850 ft., avg length = 870 ft.) • Top 30 average = 11.7 (7.2*) / MVM (avg radius = 1780 ft., avg length = 807 ft.) • Worst (of top 30) = 78 / MVM • 5% of crashes occur at top 30 locations (1% of curves) • 11% of fatals occur at top 30 locations • * Weighted average
