摘　　要：高架道路对维持城市交通的正常运行能起到重要作用,为探索高架道路出口区域交通拥堵原因,从交通流可靠性理论出发,选择概率可靠性评价指标,提出基于驾驶行为的高架道路出口匝道交通流可靠性模型,并通过实例进行分析。结果表明,该模型能够很好地表征高架道路出口匝道交通流运行的可靠程度。Elevated roads play an important role in maintaining the normal operation of urban traffic.In order to alleviate the traffic congestion problem for off-ramps of elevated roads,this paper studies the reliability theory for traffic flow.Firstly,the probability reliability evaluation index is selected and then the driving-behavior-based reliability model is built for the traffic flow for the off-ramps of the elevated roads.Finally,the case analysis is taken by the model.The result indicates that the proposed model can express the operational reliability level for the off-ramps of the elevated roads very well.
