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
2
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
3
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.)

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

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
