The invention discloses a road feature portrait generation method and system, a medium and electronic equipment, and the method comprises the steps: receiving a road feature portrait generation instruction of a target road, the feature portrait generation instruction carrying a target road identifier; acquiring local input flow characteristic parameters, local correction parameters and lane characteristic parameters of the target road from a preset local parameter library according to the target road identifier; and generating a road feature portrait of the target road according to the local input flow feature parameters, the local correction parameters, the lane feature parameters and a pre-constructed standard road feature portrait model. Therefore, by adopting the embodiment of the invention, the extracted road feature portrait is dynamic, related, continuous and open, the coupling relation among the event, the flow and the congestion contained in the road operation can be extracted, and the future development situation of the event can be accurately researched and judged under any scene and condition.

    本申请公开了一种道路特征画像生成方法、系统、介质及电子设备,方法包括:接收目标道路的道路特征画像生成指令,特征画像生成指令携带目标道路标识;根据目标道路标识,从预设的本地参数库中,获取目标道路的本地输入流量特征参数、本地修正参数、车道特征参数;根据本地输入流量特征参数、本地修正参数、车道特征参数及预先构建的标准道路特征画像模型,生成目标道路的道路特征画像。因此,采用本申请实施例,所提取的道路特征画像是动态的、联系的、连续的、开放的,可提取道路运行所包含的事件、流量和拥堵间的耦合性关系,能在任意场景和条件下对事态的未来发展态势做出准确的研判。
