The OD matrix backstepping method based on sections of bus lines

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.
