The invention provides a traffic state estimation method, device and equipment and a readable storage medium, and relates to the technical field of road traffic. The method comprises historical data and partial vehicle information which can be obtained at the current moment, and a state estimation function calculation formula and a covariance function calculation formula which are obtained by deducing and consider driver heterogeneity, which replace a state estimation function and a covariance function in the existing Kalman filtering function; compared with the prior art, random data does not need to be extracted, so the calculation time is shortened, and the real-time estimation of the traffic state is realized.
本发明提供了一种交通状态估计方法、装置、设备及可读存储介质,涉及道路交通技术领域,包括历史数据以及当前时刻可获取的部分车辆信息,通过推到得出的考虑驾驶员异质性的状态估计函数计算公式和协方差函数计算公式,并替代了现有卡尔曼滤波函数中的状态估计函数和协方差函数,与现有技术相比无需再抽取随机数据,缩短计算时间实现交通状态的实时估计。
