摘要
为提高道路交通事故的预测精度,根据道路交通安全系统的特征,提出一种基于LS-SVM算法的道路交通事故的非线性组合预测模型。实例计算表明该组合预测模型不仅比单一预测技术的预测效果更好,而且相对于已有的组合预测模型也显示出更好的预测效果,在交通事故的预测方面具有一定的应用价值。
In order to improve the predictive precision for road traffic accident,a nonlinear combination forecasting of road traffic accident was presented according to the characters of road security system based on LS-SVM.From the practical employment,the result obtained indicates that the combination forecasting approach proposed in this paper is not only more effective than the single forecasting model but also achieves better effect compared with the existing combination forecast model,it is proved to be applicable for the forecasting of road traffic accident.
