How to Understand a City via Mobility

Recent advancements in data science technologies have allowed researchers to utilize large-scale records of human mobility to study various topics from city growth models to tracing outbreaks and analyzing the labor market. In this paper, after introducing recent studies on human mobility using transportation data, we briefly review the existing studies by applying large-scale human mobility data to three different topics: epidemics, economics, and science of science. As the early attempts of interdisciplinary studies, these studies reveal how human mobility records can help us solve significant social, economic, and public health issues in our era.
