To cope with rapid population growth and the impact of climate change, Transit Oriented Development and densification are put in stage as sustainable urbanization alternatives. While the development of transit-stations and transport nodes has an undeniable role in urban transitions, their potential in promoting sustainable living is even greater when developed as a batch. Connecting transit-stations can establish a polycentric network system in which nodes combine efforts to reach regional goals, such as compact, circular, zero carbon cities. By proposing a debate on multi-layered sustainability challenges of transit-stations in polycentric networks, this paper poses the basis for new research on digitization and use of data in design of station areas. Through the case of Los Angeles,[1] counting on just 1% of the county’s land to densify living around the subway stations on Wilshire Corridor, the paper explores how the development of nodes can sustainably accommodate the population growth in metropolitan areas. This research, conducted by UCLA Architecture and Urban Design in 2015, proposes an integrated approach on absorbing 1.5million inhabitants, transitioning to clean energy, locally sourced water, and enhancing ecosystem health by 2050. In Europe in 2020, the Dutch government combines the social challenge of building 1 million homes in the existing urbanized landscape in metropolitan areas with improved accessibility systems, climate change, energy and mobility transitions.[2] Connecting the two case studies, this paper intends to identify key factors to support the planning and design of transit-stations and reflect on the use of urban data exploited to create sustainable urbanization.
