Embedding Shared Life Experience Metric in Urban Design Framework

Historically cities are formed to provide interaction and communication opportunities for population. As cities become smarter, virtual interactions are replacing human interactions and the necessity to participate in activities such as traveling to a grocery store is replaced by submission of an online shopping order in Amazon fresh. As we move in this direction, it bears answering the question of what kinds of societal loss should we expect in our future cities? In this paper, the authors introduce Shared Life Experience (SLE) metric, focusing on the interaction opportunities between urban dwellers. This metric is defined and measured by pairwise reachability and interaction probabilities of city dwellers in the context of time and space. Furthermore, the authors present a framework discussing how this metric can be embedded into design of a more dynamic urban form. The proposed bi-level model, is composed of a heuristic search algorithm in the upper level to estimate the regional SLE value for a given set of parameters and finding the best set of parameters, where the lower level activity based models produce mobility behavior of individuals in response to changes in those parameters. Using two cases studies, the authors demonstrate application of the model in urban design problems for a hypothetical network and also they present how to quantify SLE index using household travel survey data collected in five boroughs of New York City.
