基于路段公交线路OD矩阵反推方法研究

The OD matrix backstepping method based on sections of bus lines

提出基于路段公交线路客流量的OD矩阵反推方法,通过路段调查获得选取路段上的所有公交线路的客流量,借助EMME3软件强大的子矩阵选择功能对OD矩阵进行分块调整并叠加,以此推算整体客流分布的OD矩阵,从而简化调查内容,提高数据的实效性,为实践应用提供简化算法,进一步提高矩阵反推的精度。

This study put forward the OD matrix backstepping method based on sections of bus lines,select all bus lines of traffic though the section of road survey,with powerful software EMME3 selection matrix of OD matrix and block adjustment superposition,as the projected distribution of the overall passenger flow OD matrix,which simplifies the investigation to improve the effectiveness of data,in order to simplify the algorithm to provide practical application,to further improve the accuracy of inverse matrix.
