The invention relates to the technical field of intelligent traffic, in particular to an urban resident group transfer mode discovery system based on traffic OD data, which comprises an IC card data unit and a central processing unit, the output end of the IC card data unit is connected with the input end of a data acquisition unit, and the output end of the data acquisition unit is connected with the input end of a personal OD database. According to the urban resident group transfer mode discovery system based on the traffic OD data, passenger flow OD inference is carried out in combination with a trip chain method and two station attraction right methods, the uncertainty of prediction only according to the station attraction probability is effectively improved, in addition, a clustering method based on the passenger flow density is provided, clustering is not only based on the geographic position, and the system has the advantages of being high in practicability and the like. According to the method, the effectiveness of hot spot area discovery is ensured, a high-dimensional modeling module and a non-negative tensor module are proposed to excavate a significant transfer mode, groups with great transfer requirements and transfer spatial-temporal characteristics of the groups are represented, and data support and reasonable suggestions are provided for public transport line optimization and dynamic vehicle scheduling.
本发明涉及智能交通技术领域,具体为基于交通OD数据的城市居民群体换乘模式发现系统,包括IC卡数据单元和中央处理器,IC卡数据单元的输出端和数据采集单元的输入端连接,数据采集单元的输出端和个人OD数据库的输入端连接。该基于交通OD数据的城市居民群体换乘模式发现系统,本发明结合出行链法和两种站点吸引权法进行客流OD推断,有效的改善了仅根据站点吸引概率预测的不确定性,另外,提出了基于客流密度的聚类方法而不只是基于地理位置聚类,保证了热点区域发现的有效性,提出高维建模模块及非负张量模块挖掘显著换乘模式,代表换乘需求极大的群体及其换乘时空特征,为公共交通线路优化以及动态车辆调度提供了数据支撑和合理建议。
