• Abstract:
  The objective of this study was to investigate the relationship between roadway and environment-related factors and truck ; crash severity at horizontal curves located on rural, two-lane state highways in Kansas. Single vehicle truck crashes and ; multi-vehicle crashes involving at least one truck were extracted from the Kansas Department of Transportation’s crash and ; roadway databases for the years 2006-2010, resulting in 452 crash records. Descriptive statistics and 95 percent confidence ; intervals were constructed for an odds ratio analysis comparing single-vehicle truck crashes to multi-vehicle crashes involving ; at least one truck for the variables that were included in both databases. Overall, the odds ratio analysis indicated that single ; vehicle truck crashes were less likely to occur on wet pavement with shoulder rumble strips present and during non-adverse ; weather conditions compared to multi-vehicle crashes involving at least one truck. Single-vehicle truck crashes were also ; more likely to result in an injury crash compared to multi-vehicle crashes involving at least one truck. The latter were more ; likely to result in a fatality or property damage only crash.
