The invention discloses an interlaced area road traffic capacity reduction calculation method under the influence of a traffic accident. The method comprises the following steps: constructing an interlaced area road traffic flow operation characteristic data set; calculating the standard traffic flow of main road driving-out and branch road afflux of the road in the interleaving area; determining a space range of roads in the interlaced area influenced by traffic accidents; calculating the road traffic capacity reduction value of the interlaced area under the transverse influence of the traffic accident; calculating a road traffic capacity reduction value of the interlaced area under the longitudinal influence of the traffic accident; and calculating the total reduction value of the traffic capacity of the interlaced area under the influence of the traffic accident. The method can effectively quantify the influence of sudden traffic accidents on the road traffic capacity of the interlacing area, and calculates the traffic capacity reduction value of the area, so that more efficient traffic control measures can be taken at the upstream section of the road of the interlacing area, and the influence of the traffic accidents on the road traffic efficiency of the interlacing area is reduced to a greater extent.

    本发明公开了一种交通事故影响下交织区道路通行能力折减计算方法,包括步骤:构建交织区道路车流运行特征数据集;计算交织区道路主路驶出与支路汇入标准车流量;确定交织区道路受交通事故影响的空间范围;计算交通事故横向影响下交织区道路通行能力折减值;计算交通事故纵向影响下交织区道路通行能力折减值;计算交通事故影响下交织区道路通行能力总折减值。本发明可有效量化突发交通事故对交织区道路通行能力的影响、计算该区域通行能力折减值,以便在交织区道路上游路段采取更加高效的交通管控措施,从而更大限度的降低交通事故对交织区道路通行效率的影响。
