Road Transport System Analysis and Development Measures

Shiwu Li

Abstract

AbstrcatIn this paper,structure of road transportation system and the relationship among its subsystems were analyzed.Using the research method of system dynamics,the relationship among road transportation system and its main external factors was analyzed,and the causality-feedback-loops were studied,such as road transportation and social economy causality-feedback-loop,road transportation and other modes of transportation causality-feedback-loop,road transportation and science and technology development causality-feedback-loop,road transportation and environment causality-feedback-loop,road transportation and security causality-feedback-loop,road transportation and transport price causality-feedback-loop.On the base of the analysis,some countermeasures and suggestion of developing road transportation were proposed pertinently.
