The Federal Highway Administration (FHWA) has identified roadway departure as a focus area because roadway departure crashes consistently contribute to more than half of the fatal crashes on U.S. roadways. Access to relevant data is critical to understanding the causes of roadway departure and mitigating the consequences. This study seeks to maximize available vehicle and infrastructure crashworthiness data sources and repurpose them to answer questions of interest to FHWA, such as the identification of barrier types and end treatments subjected to specific crash conditions previously unreported in the crashworthiness datasets.
This study is part of a series of low-cost in-house efforts to make full use of existing data resources to understand the roadway departure problem. Existing data will be extrapolated and interpolated to determine reliable results and identify missing data. This report represents an ongoing effort in roadway departure analysis.

16. Abstract
This work represents the first phase of an ongoing low-cost in-house effort to perform data analysis, optimize internal data gathering in an informed fashion, make data requests to organizations, and obtain needed information. The work also calls on the definition of “roadway departure” prepared by a 2008 working group assembled by the Federal Highway Administration (FHWA) Office of Safety. The group provided a verbal and data definition in order to extract data and relate the data to the fatal crash population.
Many applications exist for crashworthiness data and untapped resources from previously unqueried sources.(1) The FHWA roadway departure definition provided a Fatality Analysis Reporting System data approach; however, other National Highway Traffic Safety Administration datasets exist with real-time or near real-time data.(2) One such dataset is the National Motor Vehicle Crash Causation Study (NMVCCS).(3,4) The present work pursues photographic data extracted from the NMVCCS. This report provides further discussion regarding the surrogates adopted in framing roadway departure. |
