EVALUATION UNDER 3E PRINCIPLE FOR URBAN RAPID RAIL TRANSIT NETWORK PLANNING BASED ON GREY INCIDENCE ANALYSIS

摘要

Different with traditional urban rail transit network, urban rapid rail transit network planning is a system planning in a greater region with multi-level multi-factor and multi-objective. Great significance of evaluation index system of urban rapid rail transit network planning has been shown in the urban rapid rail transit development. Based on the analysis of evaluation index system of urban rapid rail transit network planning in different cities and the "3E" principle (Economy, Environment, Equality) that was used in Metropolitan and Comprehensive Transportation planning, evaluation index system of urban rapid rail transit network planning is reorganized .And then gray incidence analysis method is carried out to evaluate the latest urban rapid rail transit network planning in Chengdu of China, the best one in five plan alternatives is selected. The result turns out that the "3E" principle is much more guidable for the evaluation index system, and grey incidence analysis method is much more effective. By this article, in the real practice of urban rapid rail transit network planning in Chengdu of China in 2010, scientific decision support is provided and shows high-grade result.
