摘要：Transportation activities, services and infrastructure development have significant and long lasting economic, social and environmental impacts, and are among key components of urban sustainability. To assess transportation sustainability, various attempts have been made to develop and deploy quantitative indicators at different geographical scopes. Few studies have applied these indicators to compare urban sustainability. In this paper six selected cities in Africa are characterized, ranked and compared with other world cities in the context of urban transportation sustainability. The relevant information was extracted fro m centralized databases. The International Association of Public Transport, UITP, was the key so urce of pertinent information. The study consisted of three major stages. Firstly, the study database was constructed and preliminary statistical analyses were conducted. Secondly, relevant sustainable transportation indicators, reflecting the three major dimensions of environmental, economic and social sustainability, were developed and deployed. Thirdly, utilizing the developed indicators, an o verall composite ind ex was developed and suggested. The comparative appraisal of the o verall composite index for the selected cities in Africa showed that their positions were far from ideal when compared with other regions of the world. Nevertheless, significant variation was observed among the selected African cities. This study suggests and provides a methodology for comparative appraisal of urban transportation sustainable develop ment. Decision and policy makers may deploy the study ap proach for other locations and geographical scop es to address issues pertinent to transportation sustainability
