3MT Competition at the Second Academic Forum of Jiangsu Graduate Students

It was a great honor to represent my university at the Jiangsu Graduate Academic Forum and share our recent research published in Cities. In this work, we proposed the concept of the Vertical 15-Minute City, extending the traditional 15-minute city framework into the vertical dimension of urban space.

By integrating multi-source urban data, we predicted urban functions at the floor level and formally incorporated stair travel time and elevator travel time into accessibility analysis. Our findings reveal that conventional two-dimensional accessibility assessments can systematically overestimate real-world accessibility when vertical mobility is ignored.

The forum emphasized interdisciplinary exchange and adopted the Three-Minute Thesis (3MT) format for presentations. Communicating complex urban analytics within such a constrained timeframe was both challenging and rewarding. The cross-disciplinary audience and diverse perspectives sparked many insightful discussions and offered valuable reflections on how urban research can be made more accessible to broader audiences.

I got to meet many talented graduate students from various fields, and the experience has inspired me to continue exploring innovative ways to communicate urban research effectively. Moreover, I got excellent academic presentation in this competition.
