However this is not a fortuitousness, because the Industrial Revolution brings the economical transportation development urges now society's high development, this and the transportation also has the indelible stake, therefore the transportation vehicle change all has to the social humanities or the economy very in a big way pushes the near function, we must grasp the social life infinite, the control transportation take the initiative!

然而这并不是偶然性，由于工业革命带来的经济交通发展促使当今社会的高度发展，这和交通也有着不可磨灭的利害关系，所以交通工具的变化对社会人文还是经济都有着很大的推近作用，我们要把握社会命脉，掌控交通的无限先机！

The thesis made a study on the construction of the road transportation in Inner Mongolia. Through analyzing the social economys development, the present of synthesis transportation and the infrastructure, the equipment of goods traffic and the present situation of the operation and the management, the problems between road transportation and social economic development in the structure in Inner Mongolia were pointed out. Then the methods of regression forecast, flexible coefficient, and straight line tendency forecast etc were used to estimate the quantities of the goods and Freight Ton-kilometers. According to the future demands of goods volume of road transported and the development of freight transportation turnover quantity in Inner Mongolia and the existence question, the adjustment plan of the road goods traffic station yard layout, network structure transports strength structure and service system have been proposed, and then the synthesis appraisal of the plan has been carried on, the Inner Mongolia road goods traffic structure adjustment safeguard measure was proposed.
