Title: Evaluation of Large Truck Crashes at Horizontal Curves on Two-Lane Rural Highways in Kansas
Abstract: The objective of this study was to investigate the relationship between the roadway, environment, and resulting crash severity of truck crashes 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 crashes were extracted from the Kansas Department of Transportation’s crash and roadway databases for 2006 to 2010 which resulted 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 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 the shoulder rumble strips present, occurring during non-adverse weather conditions as compared to multi-vehicle crashes involving at least one truck. Single-vehicle truck crashes were also more likely to result in an injury crash as compared to multi-vehicle crashes involving at least one truck which were more likely to result in a fatality or property damage only crash.
