Modelling a low-carbon city

Abstract

In a Middle Eastern environment typified by very rapid development growth, a strong emphasis on use of the car, low fuel costs, an evolving public transport system, an extremely aggressive climate and a complex socio-economic framework, Masdar City in Abu Dhabi aspires to become of one of the most sustainable cities in the world. Gaining from the experience in Masdar City, this paper explores and highlights the general requirements and challenges in developing a modelling system to assist with the sustainable planning and implementation of an integrated virtually carbon dioxide-neutral transport system, which includes the option of an innovative electric transport system such as personal rapid transit (PRT). The paper identifies travel demand and supply characteristics to be considered and explains the specific modelling requirements compared with more conventional situations. Key considerations are the quantification of demand patterns, determination of public transport and PRT patronage, the integration between external and internal systems and verification of the performance of all system components.
