- Abstract
At present, many researches use vehicle trajectory data to identify rapid deceleration driving behaviors, but the existing fixed threshold method can not distinguish different driving scenes and lack of modeling analysis. Based on the car following model, a method to judging rapid deceleration driving behavior which include multiple driving scenes was proposed. Some parameters were considered in this method, such as lighting conditions, weather, road speed, and solves the problem of lacking scene classification. Clustering algorithm was used to distinguish the rapid deceleration driving behavior in the historical data, actual threshold was extracted and compared with the model results to verify the accuracy of the method. The results show that the model has good adaptability and high accuracy for different driving scenes. Compared with the existing method, it is proved that the method can better identify the rapid deceleration behavior, then it can offer a foundation for driving safety research.
