Current progress on the Urban Data Model (UDM) Platform and the Dynamic Bus Routing prototype. See the roadmap for the ongoing development of the UDM. Here is a video showing the current state of the simulation running.
The Dynamic Bus Routing prototype has now implemented the following feature:
loading of street network from a postgis database
bus traversal on the street network
definition of catchment zones based on Voronoi analysis of bus current route nodes
assignment of riders for pickup which fall into those zones
rerouting based on new rider pickup locations, and drop of locations once rider is picked up
Next steps include:
Fix the voronoi polygon union issue – current approach (polygon -> multipolygon) is fast but creates a bunch of strange boundary lines that are very distracting. Need to find a better solution for joining all the polygons to draw clean boundary lines between bus catchment zones!!!
Work on display layer issues, possibly using PGraphics objects to create multiple display “layers” – i.e. a UI layer on top, followed by an annotation layer, a draw layer, and finally a background layer on bottom.
Providing a rider handling system so that certain bus catchments don’t become too large (solving the problem that as more riders are assigned, the catchment becomes larger, causing more riders to be assigned, and so forth)
After over two months of work, and so much help from Nicholas, Amanda, the crew at K1ND, Yanglei, Sheng Qiang, and his students at Beijing Jiaotong University, and of course Bea, Evelyn and the rest of the team at Beijing Design Week, the Octopus Pavilion has finally come fully to life! Opening party on September 24th was a big hit. Thanks all for the incredible work, perseverance, and support from everyone involved!!
The fabric officially moved onto site this afternoon. One team remains in the studio working on the assembly, while a second team has moved to the site to start installing the fabric cells. Things are moving fast now, though sadly we won’t get the canopy finished before Nicholas leaves tomorrow morning. He will be there in spirit for sure when it finally lifts off the ground and comes to life. Nicholas thanks so much for all your hard work, this project would never have been possible without you!
The latest visualizations and drawings of the project, closing in on a final design. Prepared for use during a presentation to the residents tomorrow morning. Work continues on the overall structure, connection details, the fan+controller carriage, and software. Controllers are being fabricated now by our partner, K1ND. One more day of planning and final design, cell fabrication will start in full on Tuesday.
First simulation of the inflation form with random fixed vertices. Face color defined by the distance of the inflating face centroid from the original centroid position. Hoping to use some development of this for the fabrication workshop later this summer. Built off the toxiclibs physics library in Processing, and this sketch in particular. Unfolded using Pepakura.
The Soft City Platform will be part of the 2016 Beijing Design Week in the historic Baitasi (White Stupa Temple) neighborhood of Beijing. The platform will include the installation of the octopus pavilion, an inflatable structure incorporated into an existing Hutong courtyard. This pavilion will host a series of events, including the Soft City forum, with interdisciplinary panels discussing how the increasing integration of technology, ecology, economies, and politics are changing the way we think about and design in and through the city.
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.
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.
