Optimization of the Structure of Comprehensive Transportation Systems Based on Energy Consumption

Abstract

In recent years, with rapid development of the comprehensive transportation system, the contradiction between transportation and energy has become more and more serious; energy has become a constraint to the sustainable development of China's comprehensive transportation system. How to optimize the comprehensive transport system structure effectively and promote the comprehensive transportation system sustained development has become an important problem that urgent to be solved. This paper considers the “energy consumption” as constraints, establish decomposition model to analysis the variation of energy consumption. Research shows that, when considering the constraints, it increases the proportion of rail transport and waterway transport in a comprehensive transport system. Therefore, under the constraints of energy consumption, the system should make planning to realize the coordination of transport modes. Especially, should greatly develop railway and waterway which have low energy consumption and little effect on environment.
