1. 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. 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. 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. 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. 5 Characteristics of head-on traffic crashes in Hawaii, 2001-2005

6. 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. 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. 8 Characteristics of crashes related to running off the road in Hawaii, 2001-2005

9. 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

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

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

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