The invention relates to an urban agglomeration OD construction method fusing multi-source heterogeneous big data, and the method comprises the following steps: obtaining road passenger transport OD information based on mobile phone signaling data, expressway toll data and urban cross-border survey data; obtaining railway passenger transport OD information based on the mobile phone signaling data and the railway ticket business data; obtaining road freight OD information based on highway toll data, truck GPS data and freight POI data; and aiming at the road passenger transport OD information, the railway freight transport OD information and the road freight transport OD information, carrying out OD backstepping by constructing an urban agglomeration traffic network to complete OD construction. Compared with the prior art, the method has the advantages that the urban agglomeration passenger and freight transportation travel volume can be described in a finer spatial scale, and the reasonability and precision of the OD matrix are improved.
本发明涉及一种融合多源异构大数据的城市群OD构建方法,包括如下步骤:基于手机信令数据、高速公路收费数据和城市跨界调查数据,获取道路客运OD信息;基于手机信令数据和铁路票务数据,获取铁路客运OD信息;基于高速公路收费数据、货车GPS数据和货运POI数据,获取道路货运OD信息;针对所述道路客运OD信息、铁路货运OD信息和道路货运OD信息,通过构建城市群交通网络进行OD反推,完成OD构建。与现有技术相比,本发明能够在更精细的空间尺度刻画城市群客货运出行量,提升了OD矩阵的合理性和精度。
