The invention discloses a dynamic urban traffic scene digital twin modeling method, which relates to the technical field of traffic simulation, and comprises the following steps: step 1, obtaining real traffic scene data through a map service provider; step 2, based on SUMO, constructing a dynamic traffic simulation model according to real traffic scene data; and step 3, collecting a simulation vehicle speed track and a real vehicle speed track under the same driving route, and verifying the consistency of the dynamic traffic simulation model and a real traffic scene. According to the invention, a real urban traffic scene can be simulated, and a large-scale simulation test is carried out in a virtual environment, so that the demand for a real vehicle road test can be remarkably reduced, the development cost of a control algorithm is reduced, and the development efficiency of the control algorithm is improved.

    本发明公开了一种动态城市交通场景数字孪生建模方法,涉及交通仿真技术领域,包括以下步骤:步骤1、通过地图服务商,获取真实交通场景数据;步骤2、基于SUMO,根据真实交通场景数据构建动态交通仿真模型;步骤3、采集同一行驶路线下的仿真车速轨迹与真实车速轨迹,对所述动态交通仿真模型与真实交通场景的一致性进行验证。本发明能够模拟真实的城市交通场景,通过在虚拟环境中进行大规模的仿真测试,可以显著减少对实车路测的需求,从而降低控制算法的开发成本,并提高控制算法的开发效率。
