National Traffic Speeds Survey 3

The objectives of this project are to capture on-road travel speed data from motor vehicles; to provide national estimates of these speeds on differing roadway classes; to examine differences in these speed estimates for the various roadway classes by other variables, including but not limited to speed limit, time of day, day of week, road geometry, and vehicle type; and to compare these data with data collected in the first two national traffic speed surveys (2007 and 2009). This third national traffic speed study will develop a new sampling approach to produce a more accurate nationally representative sample of the Nation’s traffic speeds. The survey design will use geographic cluster samples of primary sampling units (PSUs) chosen to represent a range of combinations of regions of the United States, level of urbanization, and type of topography (flat, hilly, mountainous). Speeds will be measured on randomly drawn road segments on three Feature Class Code (FCC) Road Classifications. Speed measurement sites will be selected in road segments with various degrees of straight, curved, flat, and hilly geometry. As with the earlier surveys, comparisons will be made across time of day, day of week, daylight/nighttime, and vehicle length. Unlike the previous surveys, this survey will also record weather and examine differences across posted speed limits within the three road types. These data will be of use to National Highway Traffic Safety Administration (NHTSA) and Federal Highway Administration as they set policy regarding the management of speeds in pursuit of reductions in speeding-related crashes.
