Urban Traffic Mode Structure Optimization Based on Eco-Transportation

Urban eco-transportation system is the development direction of urban transportation system; urban traffic mode structure is an all-important factor that affects the realization of it. Despite a voluminous empirical research of traffic mode structure, most of them have failed to adequately consider the ecology problem. On the basis of satisfying all requirements of eco-transportation system, and according to the common problems such as traffic jam, serious traffic pollution, low efficiency of utilizing resources, this paper first proposes the idea of traffic mode structure optimization, it combines optimization with traffic planning; secondly, it analyzes the main objectives and constrains; finally, it establishes an fuzzy programming model of traffic mode optimization as a result of the uncertainty of transportation system in the future.
