Research on the Evaluation Indicator System for Sustainable Development of Urban Roads Based on the Triple Bottom Line Theory

Abstract

This study aims to explore the crucial significance of sustainable development in urban roadways, highlighting its key role in promoting economic growth, social equity, and environmental conservation. Drawing on the Triple Bottom Line theory, which encompasses economic, social, and environmental dimensions, the research analyses the impact of urban road planning, design, and management within these areas. A comprehensive set of sustainability assessment indicators for urban roads is developed using analytic hierarchy process, establishing evaluation criteria across the economic, social, and environmental dimensions. This study proposes a sustainable development model for urban roads and verifies the effectiveness of the Triple Bottom Line theory in the field of sustainable urban road development.
