Urban sustainability and the emergence of new （old） concepts： Analysis of the sustainable communities concept through the component of transportation

In this paper, I propose to analyze the sustainable communities concept through the perspective of transportation and connectivity. Sustainable communities concept gives more importance to the social dimension that is the centre of the concern, and spatially to the neighbourhood and the complex structure of interactions, activities, fluxes that characterize the urban environment. To understand the concept, I will focus on the principles that underline this concept including the seven components that were defined by Egan （2004）. There will be an approach through the evolution of transportation in cities, a contextualization of the present problems associated with this topic, the explanation of the differences between sustainable transportation and ＂common＂ transportation. The relation between land use patterns and transportation will also be addressed on how sustainable transportation can promote the sense of community in a place. In the final remarks, there will be some proposed measures associated with the concept of sustainable communities.
