The invention discloses an expressway traffic accident emergency induction shunting discrimination method, which comprises the steps: obtaining the original traffic capacity of a position where a traffic accident happens before the traffic accident, the actual traffic capacity of the position where the traffic accident happens when the traffic accident happens, and the traffic flow, the maximum queuing length and the shortest dissipation time of the congestion caused by the traffic accident of the target upstream road section during the traffic accident, comprehensively analyzing and comparingthe acquired data, and judging whether emergency induced shunting judgment needs to be carried out on vehicles in the target upstream road section. The method provided by the invention is simple, hashigh accuracy of a discrimination result, and is used for quickly and timely carrying out emergency induction shunting discrimination of the road traffic accident.

    本发明公开了一种快速道路交通事故应急诱导分流判别方法,方法包括获取交通事故所在位置在发生交通事故之前的原始通行能力、交通事故所在位置在发生交通事故时的实际通行能力,以及目标上游路段在发生交通事故时的交通流量、最大排队长度、交通事故引起的拥堵的最短消散时间,综合分析比对获取的各数据,判断是否需要对目标上游路段中的车辆进行应急诱导分流判别;本发明提供的方法简单,判别结果的准确度高,用于快速及时的进行道路交通事故应急诱导分流判别。
