The Journal of Safety Research is pleased to publish the results from two of the first research studies using the second Strategic Highway Research Program's (SHRP 2) naturalistic driving data set. SHRP 2 was authorized by the United States Congress to address some of the most pressing needs related to the nation's highway system. SHRP 2 is administered by the Transportation Research Board of the National Academies under a Memorandum of Understanding with the Federal Highway Administration and the American Association of State Highway and Transportation Officials. SHRP 2 focuses on applied research in the following four areas: • Safety — Improve understanding of driver behavior to reduce the number and severity of highway crashes • Renewal — Update aging infrastructure with more durable facilities using efficient design and construction methods that minimize disruption and work time • Reliability — Reduce congestion through incident reduction, management, response, and mitigation • Capacity — Plan and design transportation capacity with consideration of environmental and economic factors and the needs of the community. The goal of the naturalistic driving study is to gain a better understanding of the interaction among the factors involved in highway crashes — driver, vehicle, and infrastructure. Based on this knowledge, it is hoped that better safety countermeasures will be developed and applied to save lives. To obtain this understanding, the largest naturalistic driving study to date was conducted. The two studies presented in this edition are the first results from this initiative. These studies were conducted before the full data set was completed. Therefore, they are demonstration studies, and represent the type of research that is possible rather than stand as final or definitive results. Language: en |
