摘　　要：为了提高交通冲突判别的精度,综合运用交通冲突理论、相对运动理论和费歇判别原理,建立了以速度、距离和角度等变量为核心的综合交通冲突判别模型。将交通冲突判别划分为交通冲突发生判别和交通冲突严重程度判别两个阶段。对交通冲突进行了定性及定量的描述,分析了冲突的成因及冲突对象的运行规律,建立了临界冲突区域模型。运用费歇判别原理建立了交通冲突严重程度判别模型,形成了完整的交通冲突判别模型。该模型可用于预测及判别任意交通实体间的冲突,为交通冲突自动识别技术提供了理论基础。To improve the precision of traffic conflict discrimination, a comprehensive traffic conflict discrimination model was established using the traffic conflict theory, the relative movement theory and Fisher discrimination principle and taking the speed, distance and angle as key variables. The traffic conflict discrimination was devided into two phases： the occuring phase of traffic conflict and the discriminating phase of traffic conflict severity. The traffic conflicts were analyzed qualitatively and quantitatively, the causes of the traffic con{lict and the movement patterns of the conflicting objects were studied to build a critical conflict region. A model to discriminate the severity of traffic conflict was built using the Fisher discrimination principle. Thus a complete traffic conflict discrimination model was achieved. This model can be applied to predict and judge the conflict between any two of motor vehicles, non-motor vehicles, and pedestrians, providing a theoretical basis for automatic recognition technique of traffic conflicts.
