The invention discloses an expressway traffic flow induction method and system based on an unmanned aerial vehicle. The system comprises a data acquisition and processing subsystem, a cloud traffic flow simulation subsystem and an induction subsystem. According to the method, control areas are divided for frequently-congested road sections (ramps and service areas) and upstream areas of the expressway, data acquisition is carried out, cloud simulation models of the corresponding control areas are constructed, and meanwhile, real-time updating of the models is carried out according to a certain time window; after the system recognizes congestion, a speed limiting strategy is calculated through the cloud model, the speed limiting strategy is sent to the airport, the unmanned aerial vehicle departs from the designated airport, arrives at the designated position of the road section and carries out speed limiting prompting to carry out traffic flow induction, the effect of relieving the traffic condition of the congested road section is achieved, and meanwhile the system can be used for accidental accident prompting.
本发明公开了一种基于无人机的高速公路交通流诱导方法及系统,包括数据采集与处理子系统、云端交通流仿真子系统和诱导子系统。通过对高速公路常发拥堵路段(匝道口、服务区)及上游区域划分控制区,进行数据采集,构建相应控制区域的云端仿真模型,同时按照一定的时间窗口进行模型的实时更新;系统识别到拥堵后,通过云端模型计算出限速策略,将限速策略发送到机场,无人机从指定机场出发,到达路段指定位置,进行限速提示以进行交通流诱导,达到缓解拥堵路段交通状况的作用,同时可用于偶发事故提示。
