• Description:
  Background: Motor vehicle crashes on rural roads result in more fatalities and injuries than those on urban roads. Large slow-moving farm vehicles are known hazards. However, the road characteristics may influence farm vehicle-related crashes, too. Purpose: This research in progress aims to assess the effects of grade (gradient) and curvature (sinuosity) of a road segment on the incidence of crashes involving farm vehicles. Methods: A matched case-control study is being conducted using the department of transportation data from nine Midwestern states - Iowa, Illinois, Kansas, Minnesota, Missouri, Nebraska, North Dakota, South Dakota, and Wisconsin. A case is defined as a road segment where a farm vehicle-related crash occurred during 2005-2010. A control road segment did not involve a farm vehicle-related crash. ZIP code, length of the segment, road type, and number of intersections within the road segment were used to match two control road segments to each case segment. The matching variables were chosen from the minimal sufficient set of a directed acyclic graph (DAG) that addresses confounding on the effect of grade and curvature on crash incidence. Conditional relative risk models will be used to evaluate the risk of a crash on a road segment for incremental grade and curvature values. Results (Pending): Out of 6.4 million road segments in 9 states, there were 7096 case road segments from 2005-2010 and we selected 14,192 matched control road segments. Conclusions: The results of our study may influence road and traffic planning to reduce the incidence of farm vehicle-related crashes on roads. [Description provided by NIOSH]
