The invention relates to the technical field of road simulation, and discloses an expressway section congestion risk assessment method, device, equipment and medium, and the method comprises the steps: carrying out the vehicle simulation based on vehicle parameters and environment parameters of an expressway section, and obtaining the vehicle traffic flow of the expressway section; dividing the expressway section according to different division modes, calculating the vehicle dispersion degree in each division mode according to the vehicle traffic flow, and taking the division mode corresponding to the minimum vehicle dispersion degree as the optimal division mode; and performing congestion risk assessment on the vehicle traffic flow in the optimal division mode to obtain the congestion degree of the expressway section. According to the method, the congestion condition of the high-speed road is evaluated through simulation analysis, the congestion condition of the high-speed road can be reproduced and quantitatively and accurately evaluated, and an accurate and reliable scientific basis is provided for evaluation of the congestion condition of the actual high-speed road section, so that a more accurate road condition is provided for travelers.

    本发明涉及公路仿真技术领域,公开了一种高速路段拥堵风险的评估方法、装置、设备及介质,方法包括:基于车辆参数和高速路段的环境参数进行车辆仿真,得到高速路段的车辆交通流;按照不同的划分方式对高速路段进行划分,并根据车辆交通流计算每种划分方式下的车辆离散程度,将与最小车辆离散程度所对应的划分方式作为最佳划分方式;对最佳划分方式下的车辆交通流进行拥堵风险评估,得到高速路段的拥堵程度。本发明通过仿真分析评估高路道路拥堵状况,能够复现高速拥堵状况,并对高速拥堵状况进行定量的精准评估,为实际高速路段拥堵状况的评估提供准确的、可靠的科学依据,从而为出行者提供更精准的道路状况。
