Smart City Planning in Gangnam, Seoul
The application of IoT in cities is a critical component in constructing
a smart city. Seoul Metropolitan Government began installing IoT
sensors known collectively as S-DoT in 2019. S-DoT collects real-time
climate and floating population data. This study aims to introduce a
smart city planning application in Seoul, to validate the S-DoT application,
and to suggest a research framework for using S-DoT data. We analyzed
S-DoT collected floating population data to examine travel behavior,
volume, and patterns during the COVID-19 pandemic. The result showed
that micro-level spatiotemporal analysis was possible using S-DoT data,
and we identified different floating population patterns. The panel regression
result that explained the effects of urban factors on the floating population
revealed that the degree of COVID-19 seems to impact people’s travel
behavior significantly. As more S-DoT technologies are planning to be
deployed in Seoul, the city will begin to collect more sophisticated real-time
data. However, planners and policymakers should be attentive to the issues
and limitations of newly installed S-DoT systems and find better strategies
to use S-DoT data.
