基于行车数据的五急一超驾驶行为识别研究

Study on The Identification of Abnormal Driving Behavior Based on Driving Data

为实现异常驾驶行为识别,本文通过提出以高速公路上小轿车为研究对象,对“五急一超”异常驾驶行为进行了说明,并且根据驾驶行为的不同特征,提出了不同的判定条件。在高速道路条件下,超速行为的判定应设有相应的阈值,急变速也相应的有不同的限制以判定急变速驾驶行为,同时,急转向、急变道驾驶行为根据道路状况也应有不同的横向加速度阈值作为判定依据。

In order to realize the identification of abnormal driving behavior,this paper proposes to take the car on the highway as the research object,explains the abnormal driving behavior of"five emergencies and one exceedance",and proposes different judgment conditions according to the different characteristics of driving behavior.Under the condition of high-speed road,there should be a corresponding threshold for the determination of speeding behavior,and there should be different restrictions for sudden speed change to determine the driving behavior of rapid speed change,and at the same time,the driving behavior of sharp steering and sudden lane change should also have different lateral acceleration thresholds according to the road conditions as the basis for judgment.
