The invention discloses an urban traffic distribution analysis method and system based on multi-source big data, and the method can comprehensively describe the travel general situation of urban residents through integrating the big data of multiple traffic modes of buses, subways, taxis and shared bikes in a city, avoids the deviation caused by a single data source, and improves the accuracy of urban traffic distribution analysis. According to the data preprocessing, original data are converted into a unified spatial point data format, accurate analysis is ensured, OD extraction not only records a travel starting point and a travel ending point, but also calculates travel duration, a key basis is provided for travel behavior analysis, spatial and temporal distribution feature analysis comprehensively considers time and spatial scales, and a spatial interaction network of various traffic modes is revealed finely. In the step of interaction matrix construction, OD is matched to space units, an OD interaction matrix between stations or grids is constructed, travel behaviors are quantified, travel characteristics are compared to reveal travel differences in different time periods, traffic bottlenecks and hot spots are recognized, and in the step of travel mode recognition, high-frequency OD pairs and interaction areas are found, and scientific guidance and suggestions are provided for urban traffic planning and management.
本发明公开了一种基于多源大数据的城市交通分布分析方法及系统,通过整合城市中公交、地铁、出租车和共享单车多种交通方式的大数据,能够全面描绘城市居民出行概况,规避单一数据源造成的偏差,数据预处理将原始数据转换为统一的空间点数据格式,确保分析精准,OD提取不仅记录出行起点与终点,还计算出行时长,为出行行为分析提供关键依据,时空分布特征分析综合考虑时间空间尺度,精细揭示各交通方式的空间交互网络,交互矩阵构建则将OD匹配至空间单元,构建站点或网格间的OD交互矩阵,量化出行行为,出行特征比较揭示不同时间段出行差异,识别交通瓶颈与热点,出行模式识别则发现高频OD对与交互区域,为城市交通规划和管理提供科学指导和建议。
