连续模式识别技术在交通安全诊断技术中的应用

传统的直接诊断交通安全技术在排查交通安全隐患过程中,因为不能排查到小范围内事故的集聚,可能无法准确地捕捉事故发生异常路段的边界。针对不足,提出了一种新的交通安全甄别方法:连续模式识别技术,通过连续移动并对每个移动间隔进行识别可以挖掘出事故的潜在问题,准确找出具体类型事故异常的路段。给出了此方法分析步骤和操作要点,研究了连续模式识别技术定量事故异常程度的计算方法。此方法计算的重复性可借助计算机编程实现,操作简单,作为交通安全诊断的一种工具,通过正确判别交通隐患位置,从而做出相应对策,提高道路交通安全水平。

Applications of Continuous Pattern Recognition to Diagnostic Technology of Traffic Safety

In the course of investigating traffic safety threat the direct diagnosis couldn't concentrate on convergences of crashes within the limited section,so the boundary of a segment with abnormal crashes may not be captured accurately.Continuous pattern recognition is a new screening method for traffic safety diagnosis.The segments with potential problems of traffic safety could be identified by successive movement and scanning every interval.Steps and main points of analysis about the technology were given.Qua...
