Overview of presentation
  • Fatal traffic crashes (FARS data)
  • Definitions
  • Overall prevalence
  • Trends, county comparisons
  • Other factors
  • Time, day of week, driver age
  • Driver profiles
  • Non-fatal traffic crashes (MVAR/DOT crash data)
  • Definitions
  • Overall prevalence
  • Trends, county comparisons
  • Other factors
  • Driver profiles

Fatal crashes
  • Fatal crash/FARS 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 (1 crash), deaths of
    undetermined intent (7 crashes, 1 of total)
  • Excludes 37 crashes (6) that did not involve a
    Hawaii resident fatality
  • Definitions Aggressive driving 44 of crashes
    (250 of 574)
  • Speeding (driving too fast for conditions or in
    excess of posted maximum) 237 crashes
  • Most common criterion includes 95 of the
    crashes that were defined as aggressive
  • Racing 6 crashes
  • Following improperly, or improper/erratic lane
    changing 5 crashes
  • Passing violations 16 crashes
  • Reckless/erratic driving 4 crashes

Aggressive driving in Hawaii, 2001-2005
  • Total impact
  • 57 residents killed by in traffic crashes related
    to aggressive driving each year
  • Crashes involving aggressive drivers are the 4th
    leading cause of death for 16 to 40 year-old
    residents
  • 11.5 of the total of 1,719
  • Cancer is 1st (14), suicide 2nd (13), heart
    disease 3rd (12)
  • Crashes involving aggressive drivers are the 4th
    leading cause of fatal injuries for all ages
  • 10 of the total of 2,915

Characteristics of drivers involved in fatal
crashes in Hawaii, 2001-2005
indicates statistically significant
difference between aggressive drivers and other
drivers
10
Non-fatal crashes
  • Motor vehicle accident report (MVAR)
  • Criteria
  • Any crash resulting in injury, or gt3000
    cumulative property damage
  • Traffic only, i.e. crashes on public roads
  • Excludes crashes in parking lots, driveways,
    military facilities, gated sub-divisions, etc.
  • Includes residents and non-residents, intentional
    and unintentional
  • Definitions Aggressive driving
  • Value for in Other factors field
  • excessive speed 65 of aggressive drivers
  • followed too close 31
  • improper overtaking 4
  • Search of Citation field for 291C-101/102/103/1
    04/105, speed, reckless, 291-2,
    291C-42/43/45/50
  • Only 0.6 of aggressive drivers (53 citations)

Data summary for aggressive driving
  • How much?
  • 44 fatal crashes related to aggressive
    driving 17 of non-fatal crashes related to
    aggressive driving
  • Who? Younger drivers (15-17 years, 18-20
    years, etc.)
    More likely among male drivers
  • Where? Generally comparable across counties for
    fatal crashes, but more prevalent for Neighbor
    Islands for non-fatal crashes
    Increasing trend for fatal crashes for
    state
  • When? Nighttime crashes (8pm-5am) 53
    Weekend crashes
    (Sat/Sun) 52
