发布时间：2018-12-10 21:45
【摘要】：将传统交通调查和模型与新的信息技术相结合,根据大数据的特征改进交通模型的方法体系,是交通模型发展面临的极大挑战。分析交通大数据对交通模型研发的促进作用,特别是在人口及就业岗位分布、综合交通网络数据和基于交通调查的模型参数等核心数据方面的支撑作用。从相关定义、市场细分以及信息完整性三个方面阐述大数据与交通模型的一致性问题。深入讨论应用大数据改进交通调查技术、4D模型研发、出行分布目的地选择模型、轨道交通出行接驳模型、出行成本校核等交通模型关键技术。通过对比大数据和交通模型的决策分析过程,指出大数据与交通模型互动发展的途径。
[Abstract]:It is a great challenge for the development of traffic model to combine traditional traffic survey and model with new information technology and improve traffic model system according to big data's characteristics. This paper analyzes the role of traffic big data in promoting the research and development of traffic model, especially in the core data such as population and employment distribution, comprehensive traffic network data and model parameters based on traffic survey. This paper expounds the consistency between big data and traffic model from three aspects: related definition, market segmentation and information integrity. The key technologies of traffic model, such as improving traffic survey technology by big data, developing 4D model, choosing destination model of travel distribution, connecting model of rail transit, checking travel cost, etc, are discussed in depth. By comparing big data and traffic model, the paper points out the way of the interactive development between big data and traffic model.
