City-on-Demand is a technology, it gathers the demand of commuter (public transport or walking) and urban residents (public spaces) and interprets the spatial requirement and changes the city’s infrastructure accordingly. Thus creating a real-time dynamic system of demand and supply. Making a city smarter by having a demand based supply chain management of its resources. It stems from my research on Delhi, where resource (supply) and demand are mismatched and there is an explosion of image based planning resulting in a gentrified and inaccessible city; plagued by pollution, congestion, high car ownership growth, safety and lack of urban commons for its growing density.
