Developing an Integrated and Contextualized Planning and Design Framework for Livable Patterns of Urbanization in Chennai

Abstract

This article analyses the urban conditions of Chennai, India, and takes a critical look at its planning framework by considering four main aspects: the ecological structures, urban morphology, mobility, and livability. To do so, the article examines policy documents, urban form, public perceptions, and daily mobility patterns. Specific attention is focused on three layers of the urban fabric: water and ecology, transport infrastructure, and housing. First, the city's river restoration is critically assessed, with a focus on integrating the social dimension into the process. Second, the metro network is analyzed, specifically understanding its usage with respect to different user groups. Third, the densification pattern in different parts of the city is analyzed. Considering the layers of water, transport infrastructure, and housing together, the article sets out an alternative integrated approach to strategic design and planning in the city towards the goal of creating a more livable public realm. The proposed integrated framework, termed "supergrids" is a city-scale strategy that enables a large reconfiguration of the existing networks in the city, integration of ecological systems into the public space network, and a restructuring of movement patterns by upscaling the vehicular network, and aligning pedestrian connections with green networks, public transit, and important functions.
