Truck Accidents at Freeway Ramps : Data Analysis and High-Risk Site Identification

  title={Truck Accidents at Freeway Ramps : Data Analysis and High-Risk Site Identification},
  author={Bruce N. Janson and Wael M. Awad and Juan Robles},
To examine the relationship of ramp design to truck accident rates, this paper presents an analysis of truck accidents in Washington State, plus a comparison to limited data from Colorado and California. We group freeway truck accidents by ramp type, accident type, and by four conflict areas of each merge or diverge ramp. We then compare these groups on the basis of truck accidents per location and per truck-mile of travel. We found that truck accident frequencies and rates were not… CONTINUE READING
