Maturepolis Lab is part of the Department of Civil and Environmental Engineering at KAIST, in Daejeon, South Korea. We apply ideas from urban information systems, data analysis, planning, and design towards making cities resilient and sustainable, able to support a diverse and deep array of activities and residents.


David received an "Outstanding prize for Learning & Teaching Innovation Award" from KAIST, for his teaching activity in 2019. Thanks to everyone who gave their support, and our awesome TA, Wonjun No, for making it happen!


Our article on applying computer vision to assessing risky driver behavior at crosswalks was published in the journal Applied Sciences. We used CV to process hundreds of driver-pedestrian interactions at two crosswalks in Osan, South Korea, extracted behavioral features like velocity, acceleration, and separation, and used k-means clustering to categorize them and interpret their risk. Congrats to Byeongjoon Noh, who led this project and will apply it to his PhD thesis.


Congratulations to Wonjun No for successfully defending his masters thesis, on the impact of crosswalk signal timing on walksheds and accessibility from Seoul public schools. On to the PhD!


Wonjun and Junyong both won prizes at the KAIST CEE Smart City competition (PhD division) for their proposals on detecting unsafe road crossings and studying gentrification using taxi ridership data.


It was a full house for our guest speaker, Chaewon Ahn from MIT DUSP, who presented work she has done on activity sensing in public space, detecting ghost cities in China using social media data, and analyzing the strong and weak social ties that bind together the many small-scale industries of the Euljiro area of Seoul. Thanks Chaewon for the fantastic seminar!


Chanho presented his idea for improving the air quality in the city using Big-data and GIS at the KAIST CEE Smart City competition. He was awarded a silver prize. Congrats!


We traveled to Hanoi and met with our collaborators, Cuong Pham and Nam Vu, with whom we are developing techniques to assess traffic congestion from a short drone flyover, to help guide emergency vehicles on dispatch.


David presented at the 2019 Seoul Big Data Forum, on the lab's work in studying street safety through data analysis.

Wonjun delivered a fantastic presentation at Seoul Mapo district on our research on school location and social infrastructure. We received great feedback from the panel of stakeholders on what is important for students to have walkable access to near their schools, and will present a final report to the city by end of the year.
