Expanding capacity of Regional Freight Transportation Network in financial crisis

Economic or social crisis frequently occurs in the same way as tempests occur in nature. Nature is evolving in a set fashion despite sudden and dramatic changes. The integrated traffic system sometimes experiences a balanced period, and sometimes suffers crisis induced by economic or social systems. It is expected that the integrated traffic system will evolve in a beneficial way. The paper would break provisionally away from the present theory in traffic and transportation. In line with biology´s general principles (for example, evolution by natural selection, power law, etc.), a long and robust development model for a regional freight transportation network (RFTN) that can cope with the financial crisis is put forward. The RFTN of China´s highways is selected as a demonstration. A significant conclusion appears: to RFTN, collocating resource reasonably between exploiting market and expanding selfcapacity is pivotal. The increase of freight volume on the RFTN depends heavily on the network infrastructure.
