The invention provides an urban road network brittleness evaluation method based on anomaly detection. The urban road network brittleness evaluation method comprises the following steps: A, identifying abnormal edges in an urban road network based on anomaly detection; b, proposing a road network brittleness evaluation method based on an abnormal index; c, proposing a road network brittleness evaluation method based on the abnormal region; and D, analyzing evolution characteristics of urban road network brittleness. According to the method, the road network brittleness evaluation method basedon anomaly detection is constructed by utilizing actual road network operation data, and a decision maker can intuitively analyze an anomaly generation period, a propagation period and a recovery period, so that a reasonable adjustment and control opportunity is selected; according to the geographical distribution condition of the abnormal area, key area adjustment and control are carried out preferentially; frequently-occurring abnormal road sections are excavated, road section level prevention and control and dispersion measures are provided, and therefore harm caused by road network brittleness is avoided or reduced; the method has the advantages of real-time performance, systematicness, easiness in research and judgment, wide application and the like.
本发明提出了一种基于异常检测的城市路网脆性评价方法,步骤如下:A:基于异常检测识别城市路网中的异常边;B:提出基于异常指数的路网脆性评价方法;C:提出基于异常区域的路网脆性评价方法;D:分析城市路网脆性的演化特征。本发明利用路网实际运行数据,构建出一种基于异常检测的路网脆性评价方法,该方法可使决策者直观地分析异常的产生期、传播期、恢复期,从而选择合理的调控时机;根据异常区域的地理分布情况,优先进行重点区域调控;挖掘出常发性异常路段,提出路段级别的防控及疏导措施,从而避免或减少路网脆性带来的危害;具有实时性、系统性、易研判、应用广等优点。
