Abstract The paper expounds the relations between the five ways of traffic, i. e. the railway with highway, waterway^ airtransport and pipeline transport. In ordei to develop national com?munications and transportations，the necessities of speeding up the railway construction as essen?tial affair and developing actively the other ways of traffic are explained. The national and region?al railway trunk lines，main national highways，arterial waterways and main pipelines，which have significant influences on the national economy and play the important role in the networks of the coordinated transportations，should be constructed as the principal projects. The relations be?tween railways and highways are described emphatically. By taking the Gansu and Fujian Provinces as examples, it is recognized that the railways and the highways must be cooperated with each other for coordinating the developments. And thus, a communication and transporta?tion system, in which the railways and the highways are the frameworks and other traffic ways are cooperated, will be established. This system has rational distributions and advanced tech?niques and extends in all directions.
