The invention discloses a green wave speed determination method, electronic equipment and a storage medium, and relates to the technical field of intelligent traffic. The method comprises the following steps: dividing green wave coordination time into a plurality of time periods; acquiring a vehicle driving time data set of each road section on the green wave coordination trunk line in the time period; training a vehicle driving time distribution model constructed based on Gaussian mixture distribution based on the data set to obtain a target distribution result, and determining a vehicle driving time mean value corresponding to a Gaussian mixture component with a minimum mean value in the result as vehicle smooth driving time corresponding to a road section in a time period; and determining the green wave speed corresponding to the road section and/or the green wave coordination trunk line in the time period according to the smooth driving time of the vehicle and the length of the road section. According to the method, more reasonable green wave speeds which are more suitable for traffic states in different time periods can be output according to the time periods and the road sections, dynamic conversion of the traffic states of the trunk line can be well adapted, and the traffic flow unblocked effect on the green wave coordinated trunk line is good.

    本申请公开了一种绿波速度的确定方法、电子设备及存储介质,涉及智能交通技术领域。其中,该方法包括:将绿波协调时间划分为多个时间段;获取时间段内,绿波协调干线上各路段的车辆行驶时间数据集;基于数据集对基于高斯混合分布构建的车辆行驶时间分布模型进行训练得到目标分布结果,并将结果中均值最小的高斯混合分量对应的车辆行驶时间均值,确定为时间段内路段对应的车辆畅通行驶时间;根据车辆畅通行驶时间和路段的长度,确定时间段内路段和/或绿波协调干线对应的绿波速度。本申请可按时间段、按路段输出更合理、更契合不同时间段交通状态的绿波速度,可以很好的适应干线交通状态的动态变换,使得绿波协调干线上车流畅通效果较好。
