  1. Hawaii Strategic Highway Safety Plan:FACILITY DESIGN Dan Galanis Injury Prevention and Control Program Hawaii Department of Health 1250 Punchbowl St., Room 214 Honolulu, HI 96813 Ph: 586-5943 E-mail: daniel.galanis@doh.hawaii.gov

  2. Overview of presentation on Facility Design • Three main areas: • Head-on collisions • Running off the road • Crashes at intersections • Fatal traffic crashes (FARS data) • Non-fatal traffic crashes (MVAR/DOT crash data) • Traffic only, i.e. crashes on public roads • Excludes crashes in parking lots, driveways, military facilities, gated sub-divisions, etc. • Unintentional in nature • Excludes suicides, deaths of undetermined intent • Available for fatality data only

  3. Head-on collisions -- definitions • Includes only crashes on non-junction sections of roadways • Excludes crashes in intersections or “intersection related”, “junction area”, “off road”, etc. • Excludes crashes involving pedestrians or bicyclists • Includes collisions described as • “head-on” • 69% of fatal cases, 30% of non-fatal cases • “sideswipe—opposite direction” • 8% of fatal cases, 36% of non-fatal cases • “angle—opposite direction” • 22% of fatal cases, 34% of non-fatal cases

  4. Annual number of fatal and non-fatal head-on* traffic collisions in Hawaii, 2001-2005(Includes only non-intersection crashes. *“Head-on” includes sideswipe and angle collisions in opposite directions.)

  5. Characteristics of head-on traffic crashes in Hawaii, 2001-2005

  6. Running off the road -- definitions • Excludes crashes involving pedestrians or bicyclists • Includes only crashes on non-junction sections of roadways • Excludes crashes in intersections or “intersection related”, “junction area”, etc. • Fatal crashes (FARS) include crashes due to “failure to keep in proper lane” • 64% of those described as ROR, including all 64 from 2004-2005 • Non-fatal crashes includes crashes due to… • “Overturned/ran off roadway” (Harmful Action section) • non collision: 35% of ROR • “Collision w/ object” (Harmful Action section)—not other vehicle: • Guardrail (7%), island/raised median (8%), embankment/wall (9%), utility pole (9%), etc.---total: 53% of ROR • Vehicle collision “Off-Roadway” (Location of Harmful Event section): • 9% of ROR

  7. Annual number of fatal and non-fatal traffic crashes involving running off the road in Hawaii, 2001-2005(Includes only non-intersection crashes.)

  8. Characteristics of crashes related to running off the road in Hawaii, 2001-2005

  9. Crashes at intersections -- definitions • Includes crashes at intersections and those coded as “intersection related” (FARS) and “intersection area” (DOT) • Excludes crashes in driveways, alleys, entrance/exit ramp, etc • Priority sequence: pedestrians > bicyclists > motorcyclists > occupants • E.g. motorcyclist hitting a pedestrian  pedestrian crash

  10. Distribution (number and percent) of fatal and non-fatal traffic crashes in intersections in Hawaii, 2001-2005

  11. Annual number of fatal and non-fatal traffic crashes in intersections in Hawaii, 2001-2005

  12. Characteristics of vehicle crashes at intersections in Hawaii, 2001-2005

  13. Characteristics of pedestrian/bicyclist crashes at intersections in Hawaii, 2001-2005

  14. Fatal traffic crashes in Hawaii, by type of crash and posted speed limit, 2001-2005

  15. Fatal traffic crashes in Hawaii, by type of crash and traffic way flow, 2001-2005

  16. Fatal traffic crashes in Hawaii, by type of crash and roadway function class, 2001-2005

  17. Fatal traffic crashes in Hawaii, by type of crash and relation to roadway junction, 2001-2005
