The invention relates to an urban traffic model construction method fusing mobile phone signaling and travel survey data, which comprises the following steps: acquiring mobile phone signaling data, and extracting grid-level resident travel information from the mobile phone signaling data; in the trip generation stage, based on population and post survey data, grid-level resident trip information is corrected through a regression method; in the travel distribution stage, OD sample expansion is carried out according to the operator market occupancy rate based on the corrected grid-level resident travel information, and an OD matrix in the future year is predicted through a gravity model; in the mode division stage, a mode transfer curve in the future year is predicted through a growth coefficient method by utilizing travel survey data; in the traffic distribution stage, the traffic distribution result is checked by using the check line traffic volume survey data in combination with the regression method. Compared with the prior art, the method has the advantages that the travel survey data and the mobile phone signaling data with large sample size and high timeliness are fused, so that the construction and correction of the urban traffic model are realized, and the accuracy of the model can be effectively improved.

    本发明涉及一种融合手机信令和出行调查数据的城市交通模型构建方法,包括:获取手机信令数据,从中提取栅格级居民出行信息;在出行生成阶段,基于人口和岗位调查数据,通过回归方法,对栅格级居民出行信息进行修正;在出行分布阶段,基于修正后的栅格级居民出行信息,根据运营商市占率进行OD扩样,并通过重力模型预测未来年OD矩阵;在方式划分阶段,利用出行调查数据,通过增长系数法,预测未来年的方式转移曲线;在交通分配阶段,利用查核线交通量调查数据,结合回归方法,对交通分配结果进行校核。与现有技术相比,本发明将出行调查数据与样本量大、时效性强的手机信令数据相融合,以实现城市交通模型的构建与校正,能有效提高模型的准确性。
