Principle analysis on coordinate development of road transportation supply system

The road transportation supply system develops coordinately,which is beneficial to exert the function of road transportation.Based on the viewpoint of system theory,the authors divide the road transportation supply system into five subsystems: road basic facility,transportation basic facility,transportation instruments,human resources and transportation software,and think that proper development of every subsystem is the intention of coordinate development of the road transportation supply system.The authors make deep research from the two ways:how to develop moderately the each subsystem and how to realize the coordinate development among the five subsystems,then put forwards that the coordinate development of road transportation supply system must conform to value flow rule and specific property of every subsystem.
