Data Visualization for Urban Area Management utilizing ICT

Authors: Yoshiyasu Suzuki, Yushi Yoshida and Mariko Doi from Nikken Sekkei Research Institute

Description: This dataviz studies the distribution of stores in the underground mall “Santica” located in the center of the Sannomiya district in Kobe City using technologies such as AI and IoT. Based on the simulation of visitors and their movements around the mall, this dataviz aims to increase visits to the mall and sales by reorganizing the shops according to consumers’ behaviour.

Therefore, it is expected that this will lead to an increase for coaching systems that use location information to offer personalized remote training. This dataviz shows location information using Apple Watch and can be used as a more economical training tool in the COVID-19 context.
