definition
Definition
  • CODES DBS: a database resulting from linking motor vehicle crash records (Crash), Emergency Medical Services records (EMS), Hospital Discharge records (HDD) and Death Certificates.
definition cont d
Definition (cont’d)
  • A Commercial Motor Vehicle (CMV): Any truck having at least 2 axles and 6 tires, any vehicle displaying a hazardous materials placard, or any bus designed to transport 16 or more passengers including the driver
  • Current: A CMV is designated as any vehicle weighing more than 10,000 pounds, and/or designed to transport 16 or more passengers including the driver.
definition con d
Definition (Con’d)
  • Large Truck: Any truck having a gross vehicle weight rating greater than 10,000 pounds.
  • Passenger Vehicle: Any passenger car, light truck, or van weighing 10,000 pounds or less.
introduction
Introduction
  • More than 5,000 deaths occur each year in CMV crashes, accounting for about 13% of all the traffic deaths in the U.S.
  • Another 142, 000 people were injured in crashes involving CMVs in 1999
  • In 1999, the estimated average cost for CMV crashes was more than $75,000
  • Reducing CMV crashes is a national highway safety priority
purpose
Purpose
  • To understand the pattern and nature of crashes involving CMVs in Nebraska
  • To establish a baseline for CMV crashes surveillance in Nebraska
method
Method
  • Descriptive analysis using four years of Nebraska CODES data (1996 to 1999)
  • Compare injury severity, hospital charges, and various pre-crash factors between crashes involving CMVs and crashes not involving CMVs
  • Examine the differences in demographics and behaviors of drivers for two-vehicle crashes (one CMV and one passenger vehicle)
results
Results
  • Of the 170,669 motor vehicle crashes that occurred from 1996 to 1999 in Nebraska, 10,939 (6.4%) involved CMVs.
  • These CMVs involved-crashes accounted for:
  • 6.0% (26,867) of all persons involved in crashes
  • 6.1% (4,140) of all crash injuries
  • 18.4% (225) of all crash deaths
  • 9.9% ($7,907,361) of all motor vehicle crash related hospital charges

conclusions
Conclusions
  • Crashes involving CMVs tended to be severe
  • PV occupants were more likely to be injured or killed when involved in crashes with CMVs
  • PV Drivers were more likely responsible for crashes involving CMVs
  • CMV drivers were found to be impaired much less often than PV drivers in both injury and fatal crashes
recommendations
Recommendations
  • Vehicle Modifications
      • Modify the structure of CMVs to make them less likely to inflict injuries in collisions with other vehicles
      • Make trucks more visible during night
      • Improve truck braking system
slide23
Enforcement
    • Improve enforcement of existing laws against unsafe driving acts in the vicinity of CMVs.
    • Enforcing following distance and vehicle speed
slide24
Education and Training
    • Increase passenger driver education about the differences between the performance of CMVs and passenger vehicles.
    • Increase CMV driver education about passenger vehicle driver behaviors
    • Develop CMV drivers training programs focused on defensive driving technique based on PV drivers’ unsafe driving habit.
    • Train law enforcement officers about the hazards of unsafe driving acts in the vicinity of CMVs.
