Motorcycle Crash Causation Study: Volume 1-Data Collection and Variable Naming

FOREWORD

The Motorcycle Crash Causation Study, conducted through the Federal Highway Administration Office of Safety Research and Development, produced a wealth of information on the causal factors for motorcycle crashes, and its corresponding Volumes provide perspectives on what crash-countermeasure opportunities can be developed. This study used a crash- and control-case approach developed from the Organisation for Economic Cooperation and Development protocols, which as discussed in this report, has provided insights into more than 1,900 data elements that may be associated with motorcycle-crash causation. The research team produced a final report along with a 14-volume series of supplemental reports that provide an overview of the study and a summary of its observations, the data-collection forms and coding definitions, a tabulation of each data element collected from each form, and selected comparisons with previous studies. It is anticipated that readers will select those Volumes and data elements that provide information of specific interest.

This document, Volume 1—Data Collection and Variable Naming, describes the data naming conventions, lists 2,600 uniquely named variables produced in the database, and provides a means for users to identify variables of interest. This report will be of interest to individuals involved in traffic safety, safety training, crash and injury reduction, and roadway design and policy making, as well as to motorcycle- and safety-equipment designers, crash investigators and researchers, motorcycle and automotive manufacturers and consumers, roadway users, and human-factors specialists.

16. Abstract
The purpose of this study was to gather data on motorcycle crashes by intensive post-crash investigations and control motorcycle observations and interviews conducted in Orange County, CA. The study developed a dataset that researchers can access and 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 involving a total of 294 other in-transit vehicles and 11 parked vehicles. Forty crashes resulted in fatalities with 22 single-vehicle-crash and 18 multiple-vehicle-crash fatalities observed. The study compiled observations on rider, passenger, and other-vehicle driver demographics; environmental factors; factors contributing to the crash; motorcycle and other-vehicle parameters; injuries sustained; and clothing/safety equipment used. For crashes, the research team compared observations for crash and control riders, passengers, and motorcycles and other vehicles involved in the crashes. Within the crash observations, the study compiled and compared the data for single- and multiple-vehicle crashes, fatality and non-fatality crashes, along with selected previous studies and elements of the National Automotive Sampling System (NASS)/General Estimates System (GES) and Fatality Analysis Reporting System (FARS) databases.(1-3) The data are available in SAS® and Excel™ formats along with a Coding Manual defining all codes used.(4)
