The Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users authorization established the National Surface Transportation Safety Center for Excellence (NSTSCE) at the Virginia Tech Transportation Institute (VTTI). The core objectives of NSTSCE were to conduct research and develop safety devices and techniques that enhance driver performance; examine advanced roadway delineation and lighting systems; improve understanding of the impact of driver fatigue on crashes; develop and evaluate means to reduce the frequency of fatigue-related crashes; develop techniques to address age-related driver issues; and transmit project results to practitioners.

NSTSCE’s efforts were structured around a diverse stakeholders group: the Federal Government (the Federal Highway Administration (FHWA) and the Federal Motor Carrier Safety Administration), State Government (the Virginia Department of Transportation), academia (VTTI), and the private sector (General Motors® and Travelers® Insurance). The stakeholders group collectively reviewed individual project proposals from VTTI, selected proposals to be addressed by VTTI’s researchers, and allocated resources to the selected projects. NSTSCE represented a great opportunity for important safety research to be conducted in support of safety goals broader than those of any individual stakeholder.A total of 58 of the projects conducted by NSTSCE involved the direct funding participation by FHWA to develop advanced safety methods.

16. Abstract

This report summarizes the research projects undertaken at the National Surface Transportation Safety Center for Excellence (NSTSCE) under funding provided by the Federal Highway Administration (FHWA). FHWA was an important founding member of NSTSCE in 2006 and chaired the original stakeholders committee for several years. They maintained membership in NSTSCE until June 2014. With their guidance and financial contribution, 58 projects were conducted that support NSTSCE’s mission of developing and disseminating advanced transportation safety techniques and innovations in both rural and urban communities. The report is organized according to NSTSCE’s five research focus areas: enhancing driver performance, examining roadway lighting and delineation, addressing age-related issues, addressing issues of fatigue, and providing outreach. Each project contains a brief, general description about its methods and findings and identifies any deliverables.
