交通事件的发生带来严重的社会经济损耗和交通效率低下.文章提出一种基于支持向量机(SVM),利用无线传感器收集和发送的实时交通数据,判断高速公路上是否发生交通事件的方法.仿真实验表明,检测方法在大多数情况下,在检测率、平均检测时间和误报率等方面,性能良好.
The occurrence of traffic accidents brings serious social and economic losses and low traffic efficiency.This paper presents a method based on Support Vector Machine (SVM), real-time traffic data collected and sent by wireless sensor to judge whether traffic accidents occur on expressway. Simulation results show that the detection method performs well in most cases with respect to detection rate, average detection time and false alarm rate.
