The invention relates to traffic simulation, in particular to an urban traffic scene construction method based on digital twinning, and the method comprises the steps: obtaining real traffic scene information, processing the real traffic scene information according to the computing resource condition of an edge node, and obtaining the perception information of a real traffic scene; the sensing information of the real traffic scene is sent to a regional cloud center, and the regional cloud center simulates the urban traffic scene according to the sensing information of the real traffic scene; carrying out segment-by-segment decomposition under a plurality of associated traffic signals, extracting trend components and detail components from traffic parameters by utilizing wavelet decomposition, carrying out trend line convergence judgment, and constructing a possible prediction trend set; the technical scheme provided by the invention can effectively overcome the defects in the prior art that a real-time traffic simulation scene cannot be constructed due to insufficient computing power of edge nodes, and an urban traffic scene in a congestion period is difficult to accurately simulate.

    本发明涉及交通仿真,具体涉及一种基于数字孪生的城市交通场景构建方法,获取真实交通场景信息,并根据边缘节点的计算资源情况对真实交通场景信息进行处理,得到真实交通场景的感知信息;将真实交通场景的感知信息发送至区域云中心,区域云中心根据真实交通场景的感知信息对城市交通场景进行仿真;进行多个关联交通信号下的逐段分解,同时利用小波分解从交通参数中提取趋势分量和细节分量,进行趋势线收敛性判别,并构建可能预测趋势集;本发明提供的技术方案能够有效克服现有技术所存在的因边缘节点算力不足而无法构建实时的交通仿真场景,以及难以对拥堵时段内的城市交通场景进行准确仿真的缺陷。
