省域高速公路基础设施数字化应用研究

Research on Digital Application of Provincial Expressway Infrastructure

在大力发展交通强国的背景下,正全面推进交通运输基础设施和运载装备全要素、全周期的数字化。在智慧高速公路的建设中,基础设施数据感知层面有待进一步完善,高速公路各平台间的数据连接没有完全打通,依然存在着不少挑战。因此,依托福建高速数字孪生项目,结合二、三维建模技术,融合高精路网和各类动静态要素,构建了与车道级路网结合的高速公路数字孪生底座,并基于Cesium实现了二、三维要素的渲染及交互应用,创建了一套适用于省域级高速公路数字化的标准流程。将车道级路网与高速公路基础设施融合表达,实现了更加精确和美观的交通要素数字化,该应用能够为车流仿真提供基础数据支持,为高速公路数字孪生底座的行业建设提供应用参考,为高速公路全生命周期管理提供有力支撑。

Under the background of vigorously developing apowerful transportation country,the digitalization of transportation infrastructure and transportation equipment in all aspects and in all cycles is being comprehensively promoted.In the construction of smart expressway,the data perception level of infrastructure needs to be further improved.The data connection between various platforms of the expressway has not been completely completed,and there are still many challenges.Therefore,relying on the Fujian High-speed Digital Twinning Project,combining the two-dimensional and three-dimensional modeling technology,integrating the high-precision road network and various dynamic and static elements,the digital twin base of expressway is constructed combined with the lane level road network,and the rendering and interactive application of the two-dimensional and three-dimensional elements are realized based on Cesium,and a set of standard processes applicable to the provincial highway digitization is created.The integration of lane level road network and expressway infrastructure has achieved more accurate and beautiful digitization of traffic elements.This application can provide basic data support for traffic flow simulation,provide application reference for the industry construction of expressway digital twinning base,and provide strong support for the whole life cycle management of expressway.
