Strategies and Key Technologies for Low-Carbon Integrated Transportation Systems in Megacities in China

Abstract

Global climate change is an international recognized issue and the most critical challenge of the 21 st century for both developed and developing countries. Although many policy recommendations and fuel standards have already been taken in some developed countries to meet the long term goal which required the entire world to reduce carbon emissions by 50 percent by 2050, there are no strict standards and generally accepted guidelines of low carbon transportation strategic planning that have been developed. This paper analyzes and discusses current carbon emission situations and policies of urban transportation systems. The key technologies and strategy approaches that could be used to reduce carbon emissions of integrated transportation systems with the focuses on the following six areas: (1) Identification of Sources and Quantification of Carbon Emissions in Urban Transportation Systems (2) Development of Strategic Plan for Low Carbon Transportation Systems (3) Guidelines for the Development for Land Use and Urban Transportation Planning (4) Development of Balanced Multi-mode Transportation Systems (5) Methodologies and Guidelines for Megacity Travel Demand Management (6) Development of Comprehensive Systems for Evaluation of Low- Carbon Transportation System.
