The invention discloses an urban intersection traffic flow prediction method based on multi-source data fusion, and the method comprises the steps: a data processing platform is built in a computer system through a data processing platform, a MapReduce mode technology based on a Hadoop framework and a GIS-T technology, and the functions of data collection, data analysis, data model generation anddata sharing is achieved; a data warehouse is established in the platform, and the data warehouse is a structured data environment composed of scattered data and integrated data and used for traffic acquisition information and traffic information integration. By integrating and analyzing the urban traffic big data, the traffic big data is effectively integrated, the urban traffic intelligence requirements of high timeliness, knowledge traction and the like are met, the peak time of the intersection is favorably predicted according to the collection, analysis and model creation of the data, andthe urban road planning and user travel are facilitated.

    本发明公开了一种基于多源数据融合的城市路口交通流预测方法,立数据处理平台,基于Hadoop框架的MapReduce模式技术、GIS‑T技术,在计算机系统中建立数据处理的平台,用于收集数据、分析数据、产生数据模型、数据分享等功能;在平台中建立数据仓库,数据仓库由分散数据和集成数据组成的结构化数据环境,用于交通获取信息和集成交通信息。通过对城市交通大数据的集成与分析,有效地集成交通大数据,满足高时效性和知识牵引等城市交通智慧化需求,根据对数据的收集、解析、创建模型,利于预测出路口的高峰时间,便于对城市道路的规划和用户的出行。
