  • Abstract:
    Speeding-related crashes continue to be a serious issue in the United States. Attempts to address this problem through a variety of approaches have not led to a substantial reduction in speeding-related safety problems. A better understanding of speeding behavior is needed to inform development of new speeding countermeasures. New insights on speeding behavior are being gathered through naturalistic driving studies (NDS), which collect data on driving behavior from drivers as they engage in their normal dayto- day driving. The Strategic Highway Research Program 2 (SHRP2), a large naturalistic study, collected driving data from 3,539 passenger vehicle drivers over 12 to 24 months in six regional sites in the United States, generating approximately 4,200 driver years of data and up to 5.4 million trip files. The SHRP2 NDS data includes real-time vehicle records, such as GPS, speed, acceleration, braking, steering, and forward radar, as well as multiple video views around and inside the vehicle. This study, which included data from 2,357 drivers, is the first to use the SHRP2 data to examine speeding behavior.
