摘　　要：为了缓解高速公路交通拥堵,利用国道和省道实现交通分流,并有针对性地实施路径诱导策略,建立了考虑拥堵车源的区域多层交通网络混合路径诱导模型。首先,构建了由国道、省道以及湖南省高速公路组成的区域多层交通网络,标定网络链接权重。然后,定位交通拥堵车源,建立了考虑拥堵车源的混合路径诱导模型,对从拥堵车源出发的车辆实施有针对性的路径诱导,在保障缓解交通拥堵效果的同时,尽可能减少对出行者的影响。研究结果表明,该模型能够实现多层网络有效分流,有效减少路网中车辆的平均出行时间。在实际应用中,可以只对少数出行者提供路径诱导信息以降低模型的实施难度,并通过调查出行者对建议路径的接受率,制定合适的路径诱导信息发布方案。In order to alleviate traffic congestion on freeways,national highways and provincial highways are used to achieve traffic diversion,and a targeted route guidance strategy is implemented.A hybrid routing model for regional multi-layer transportation network is established,which considers the congested driver sources.Firstly,a regional multi-layer transportation network composed of Hunan freeway,national highway and provincial highway is constructed,and the link weight is calibrated.Next,the congested driver sources are located,a hybrid routing model is established by considering the congested driver sources,and the targeted routing guidance is implemented for vehicles from the congested driver sources,so as to reduce the impact on travelers as much as possible while ensuring the mitigation effect of traffic congestion.Results show that the proposed route guidance model can effectively achieve traffic diversion and reduce the average travel time of vehicles in the multi-layer transportation network.In practical applications,the route guidance information can be only sent to a few drivers to reduce the difficulty of model implementation.The acceptance rate of drivers to the suggested routes can be analyzed to develop appropriate plans for disseminating route guidance information.
