Hutong Agency

This is a project was developed by student Dongni Lu as part of the Fluid Spaces studio by Profs Sheng Qiang and myself at Tianjin University School of Architecture in the Spring of 2012. It explores the evolving relationship between the production of space and the organization of social activity in the hutong alleyways of Tianjin, China.  This project simulates the process by which these alleyway streets are shaped through the encroachment and decay of house boundary walls into the public space of the street. The patterns of occupation of the public space and the highly localized street topology serve to define one-another through this historic process of accretion. Overall the system seeks a dynamic equilibrium between the conflicting desires for the expansion of private space vs. the need for the constitution of a functional public domain for circulation, social gather, commerce, and play.


Dynamic Bus Routing

Examples of the simulation of a dynamic bus routing system running on the streets of Chicago. Work completed by Profs. Thomas Kearns + Jordan Kanter and students Adam Weissert, Haidong Fei, and Li Gong as part of the Urban Data Model Prototype Studio at IIT in 2013-2014.

bus routing diagram: indicating the process of describing catchment zones based on an updated voronoi diagram of current bus route to determine which bus in the system to assign a new pick-up to and thus rerouting the buses
process for generating riders (pickup location + destination) based on analysis of demographic data


process of assigning weighted lengths for each edge in the street graph based on various city data and spatial inputs: number of street trees, sidewalk widths, pothole complaints, expected ridership, etc.
