The Surface Accelerations Reference— A Large-Scale, Interactive Catalog of Passenger Vehicle Accelerations

There is a need for large-scale, real world, diverse, and context rich vehicle acceleration catalog that can be used to design, analyze, compare various intelligent transportation systems. This paper fulfills three primary objectives. First, it provides such through the Surface Accelerations Reference, which openly available as an interactive analytics tool well open downloadable dataset. The Reference statistically describes driving profiles of about 3,500 individuals contributing 34 million miles continuous data collected in Second Strategic Highway Research Program Naturalistic Driving Study (SHRP 2 NDS). These were created by summarizing billions longitudinal lateral epochs experienced participants. Second, this introduces standardized methodology creating so similar produced other human cohorts or automated Finally, are analyze effect roadway speed category on rates at thresholds. It observed that, median driver, up orders magnitude higher low-speed roads compared high-speed roads. will facilitate system designers tune their systems safer experiences. also allow agencies with create comparable catalogs facilitating safety behavioral comparisons between populations.
