Abstract:

Speeding-related crashes continue to be a serious problem in the United States. A recently completed NHTSA project, Motivations for Speeding, collected data to address questions about driver speeding behavior. This naturalistic driving study used 1-Hz GPS units to collect data from 88 drivers in Seattle and 76 drivers in rural Texas to record how fast vehicles traveled on different roadways. Analysis identified four basic patterns of speeding behavior. The project developed this data set to redefine speeding in terms of speeding episodes and create a new data set for analyses in terms of individual speeding episodes, and examined the influence of situational factors on the different types of speeding. Analyses of the speeding episodes identified types of speeding: speeding that occurs around speed-zone transitions, incidental speeding, casual speeding, cruising speeding, and aggressive speeding. Analyses also identified driver types: Unintentional Speeders, Situational Speeders, Typical Speeders, and Deliberate Speeders. Both types of speeding and driver types occurred across all demographic groups. Data analyses on the relationships between situational factors and speeding was conducted at a high level due to the lack of available situational data, yielding the following conclusions: (1) general riskiness of different types of speeding was corroborated by the involvement of riskier elements in speeding episodes, (2) anecdotal evidence of location-specific characteristics affecting both the occurrence and non-occurrence of speeding was found, (3) there were indirect indicators that certain aspects of the driving environment affect speeding behavior, and (4) there were clear similarities between types of speeding at both the rural and urban data collection sites.
