Development and Application of an Evaluation Method of Environmental Efficiency in Transportation System Based on Data Envelopment Analysis

Abstract

 This study attempts to apply the concept of “Eco-efficiency” proposed by WBCSD to solve a dilemma between urban mobility and environmental load in developed and developing cities over the world. Environmental efficiency model based on DEA (Data Envelopment Analysis) is developed to measure the level of environmental efficiency in urban transportation systems by considering the heterogeneity inherent in cities. The model can find the frontier cities by referring the sets of public transport-oriented, private transport-oriented and balanced cities. Consequently, it was found that the proposed method leads to a reasonable and feasible goal of transport energy consumption in each city.
