Federal Highway AdministrationTurner-Fairbank Highway Research CenterFederal Highway AdministrationThis large-scale study, based on the Motorcycle Crash Causation Study (MCCS) sponsored by the National Highway Traffic Safety Administration, gathered data on motorcycle (MC) crashes by intensive post-crash investigations and control MC observations and interviews conducted in Orange County, CA. The study developed a dataset that researchers can use to investigate additional research questions. The database provides data from 351 injury crashes and 702 paired control observations. Of the crashes observed, 82 were single-vehicle crashes, and 269 were multiple-vehicle crashes, all of which involved a total of 294 other in-transit vehicles and 11 parked vehicles; 40 crashes resulted in fatalities, with 22 single vehicle-crash fatalities and 18 multiple vehicle-crash fatalities observed. The study compiled the observations on rider, passenger, and other-vehicle (OV) driver demographics; environmental factors; factors contributing to the crash; MC; and OV parameters; injuries sustained; and clothing/safety equipment used. The study also compiled observations on the crash and control riders, passengers, and MCs and OVs involved in the crashes. Within the crash observations, the study compiled and compared the data for single- and multiple-vehicle crashes, fatal and nonfatal crashes, along with selected previous studies and elements of the National Automotive Sampling System/General Estimates System and the Fatality Analysis Reporting System databases. The data are available in SAS\uae and Microsoft\uae Excel\u2122 formats; MCCS Volume 2 defines all codes used.78
