National Highway Traffic Safety Administration (NHTSA), within the Department of Transportation (DOT), has been given the responsibility to carry out motor vehicle and highway safety programs. NHTSA is responsible for reducing deaths, injuries and economic losses resulting from motor vehicle crashes. In order to fulfill this mission, NHTSA works to understand crashes and their causes.
In order to manage and analyze the complex data associated with crash factors, NHTSA has developed the Electronic Data System (EDS). EDS is currently collection system for 5 subsystems: SCI, NASS-CDS, NASS-GES, NASS-LTCCS, and TPMS. EDS collects crash data for the first 4 subsystems, and it contains tire pressure monitoring system study data for TPMS. One more subsystem will be added by 2005. The EDS system is designed to collect information on motor vehicle crashes to aid in the development, implementation, and evaluation of highway safety countermeasures while still protecting the privacy of individuals involved in crashes.
