Title:Evaluating Relationships between Perception-Reaction Times, Emergency Deceleration Rates, and Crash Outcomes using Naturalistic Driving Data
Principal Investigators:Jonathan Wood
University:South Dakota State University
Grant #:DTRT13-G-UTC38 (MAP21)
Project #:MPC-521
RH Display ID:14194
Keywords:continuing education, crash reconstruction, crash severity, deceleration, perception, reaction time, stopping sight distance


Understanding the relationship between Perception-reaction time (PRT) and deceleration rate can improve transportation engineers understanding of human factors related to stopping sight distance (SSD), leading to improved design guidance and safer roadways. It could also improve crash reconstruction and the ability to determine what happened at crashes. Therefore, a study is needed to evaluate 1) the differences in PRT and deceleration rates between crash and near crash events and 2) the relationship between PRT and deceleration rates. The results of this research could be used by transportation agencies to improve design guidance. The results could also be used in crash reconstruction and for developing policies aimed at reducing the number and severity of crashes that occur on and near the roadway.
