The embodiment of the invention provides a vehicle following operation risk state judgment method, system and device, and belongs to the technical field of data processing, and the method specifically comprises the steps: 1, obtaining the trajectory data of a plurality of manual driving vehicles in actual road traffic; 2, all the manual vehicles are divided into K following vehicle sets, each following vehicle set comprises a front vehicle and a rear vehicle, whether the traffic scene of the following vehicle set is normal following or abnormal following is judged according to the track data and the scene discrimination function of the rear vehicle of each following vehicle set, and the traffic scene of each normal following vehicle set is determined based on the track data and the style discrimination function of the rear vehicle of each normal following vehicle set; judging that the driving style of the corresponding driver belongs to aggressive non-sensitive type, conservative non-sensitive type, aggressive sensitive type or conservative sensitive type; and step 3, according to the traffic scene of each following vehicle group and the driving style of the driver, carrying out accident risk judgment on the following vehicle group. Through the scheme disclosed by the invention, the judgment accuracy and adaptability are improved.

本公开实施例中提供了一种车辆跟驰运行风险状态判定方法、系统及设备，属于数据处理技术领域，具体包括：步骤1，获取多个人工驾驶车辆在实际道路交通中的轨迹数据；步骤2，将所有人工车辆分为K个跟驰车组，每个跟驰车组包括前车和后车，根据每个跟驰车组后车的轨迹数据和场景判别函数，判断该跟驰车组的交通场景为正常跟驰或者非正常跟驰，基于每个正常跟驰车组后车的轨迹数据和风格判别函数，判别对应驾驶员的驾驶风格属于激进非敏感型、保守非敏感型、激进敏感型或者保守敏感型；步骤3，根据每个跟驰车组的交通场景和驾驶员的驾驶风格对跟驰车组进行事故风险判定。通过本公开的方案，提高了判定精准度和适应性。
