粤港澳大湾区区域综合交通模型建设构思

Conception of Regional Comprehensive Traffic Model Construction in Guangdong-Hong Kong-Macao Great Bay Area

粤港澳大湾区作为我国最开放、经济最活跃的地区之一,交通发展已进入网络化、立体化、多模式化的新阶段,城市交通规划设计、建设决策、运营管理等如何实现区域级大范围的量化分析,科学化、精细化地评估规划决策是迫切的需求。针对省内既有模型技术架构不够完善、基础数据更新不及时、核心参数缺少标定、精细化评估分析应用相对不足等问题,结合未来湾区时空格局重构及出行规律、模式演变等发展转变,提出构建基于数据驱动的新一代区域综合交通模型体系方法,重点推进区域模型技术架构优化升级、模型数据库搭建更新、模型核心参数标定校核及模型应用测试等关键技术研究。

As one of the most open and economically active regions in China,the Guangdong-Hong Kong-Macao Great Bay Area has entered a new stage of network,three-dimensional and multi-mode development.Urban traffic planning and design,construction decision-making and operation management have been facing major challenges.How to achieve regional level quantitative analysis and scientific and refined evaluation and planning decision-making has become a very urgent demand at present.In view of the problems such as imperfect technical framework of existing models in the Province,untimely updating of basic data,lacking of calibration of core parameters and relatively insufficient application of refined evaluation and analysis,and in combination with the future development and transformation of the Bay Area's spatial-temporal pattern reconstruction,travel law and mode evolution,the method of building a new generation of regional comprehensive traffic model system based on data driving has been proposed,focusing on suchresearches on key technologies aspromoting the optimization,upgrading of regional model technical framework,model database building and updating,model core parameter calibration and verification,and model application test.
