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. The authors group freeway truck accidents by ramp type, accident type, and by four conflict areas of each merge or diverge ramp. The authors then compare these groups on the basis of truck accidents per location and per truck-mile of travel. The authors found that truck accident frequencies and rates were not significantly different by ramp type alone, but were significantly different by conflict area and accident type, both between and within ramp types. The authors also found that high volume ramps had lower rates of truck accidents per truck-mile of travel.
