Research on Evaluation Method of Driving Behavior Safety for Taxi Driver Based on Space-Time Trajectory Feature

摘要

Normalizing the driving behavior of drivers, especially those operating vehicles, is an important measure for ensuring road traffic safety. Its prerequisite is accurately assessing the safety of driving behavior. In this paper, we considered the space-time characteristics of road traffic, and grouped the GPS data of taxis according to road section and time period. First, the parameters that characterize driving behavior were extracted, and the safety indexes were obtained after standardization. Then the Delphi method was used to determine the weight of indicators. Finally, the driving behavior safety evaluation model was established. This evaluation method can be used to obtain the driving behavior safety map and the safety index of taxi drivers at different times, so as to facilitate the supervision of taxi drivers.
