The invention is suitable for the field of traffic control, and provides a traffic state optimization method and system for a traffic interleaving area, and the method comprises the steps: building an SUMO traffic state model of a to-be-optimized traffic road segment which comprises a basic road segment, an interleaving area and a ramp; acquiring historical meteorological data of the traffic road section, building a meteorological prediction module, coupling the meteorological prediction module to the SUMO traffic state model, and endowing the basic road section, the interleaving area and the ramp with different optimization weights during coupling; acquiring traffic state data of the traffic road section; meanwhile, the weather prediction module is used for predicting weather influence output of an interleaving area and a ramp connected with the interleaving area under different drainage parameters; the method provided by the invention is different from a traditional traffic signal lamp control mechanism, and provides a more comprehensive optimization scheme including drainage, weather, large model prediction and the like.

    本发明适用于交通控制领域,提供了一种交通交织区的交通状态优化方法及系统,所述方法包括:建立待优化交通道路段的SUMO交通状态模型,其中所述的交通道路段包括基本路段、交织区和匝道;获取该交通道路段的历史气象数据,搭建气象预测模块,并将气象预测模块耦合到所述SUMO交通状态模型,同时在耦合时赋予基本路段、交织区和匝道不同的优化权重;获取所述交通道路段的交通状态数据;同时通过所述气象预测模块预测交织区、与交织区连接的匝道在不同排水参数下的气象影响出力;本发明的方法不同于传统的交通信号灯控制机制,提供了更加全面的、包括排水、气象、大模型预测等方面的优化方案。
