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.
