The invention provides a city-around expressway lane dynamic distribution and entrance and exit cooperative control method, system and device and a medium, and the method comprises the following steps: collecting vehicle data, and obtaining the predicted traffic volume of entering and exiting a city-around expressway from a toll station; obtaining a congestion prediction result based on the vehicle density of the vehicle real-time data; based on the predicted traffic volume and the congestion prediction result, obtaining dynamic allocation results of various traffic volumes in different lanes of the expressway main line, and sending the dynamic allocation results to a traffic body and/or a roadside guide end in the form of a lane change guidance instruction; performing signal cooperative control on the main line lane and the ramp based on the dynamic allocation result and the vehicle data; according to the invention, different types of traffic flows can be dynamically distributed to each lane, and by implementing lane change induction, a large amount of concentration of lane change behaviors at an entrance and an exit is avoided, the length of a lane change conflict road section in an interlaced area is reduced, and the traffic efficiency is improved; meanwhile, the method is suitable for a traditional traffic scene, can also well adapt to an Internet of Vehicles scene, and is high in universality.

    本发明提供一种绕城高速车道动态分配及出入口协同控制方法、系统、设备及介质,包括以下步骤:采集车辆数据,并得到从收费站进出绕城高速的预测交通量;基于车辆实时数据的车辆密度得到拥堵预测结果;基于预测交通量和拥堵预测结果得到各类交通量在高速公路主线不同车道的动态分配结果,并将动态分配结果以换道诱导指令发送至交通体和/或路侧指引端;基于动态分配结果与车辆数据对主线车道以及匝道进行信号协同控制;本申能够将不同类型交通流动态地分配至各条车道,并通过实施换道诱导,避免换道行为在出入口处的大量集中,减少交织区内换道冲突路段长度,提升通行效率;同时,本申请既适用于传统交通场景,又能很好地适应车联网场景,泛用性强。
