A Survey on Visual Analytics in Urban Mobility

PhD Qualifying Examination

Title: "A Survey on Visual Analytics in Urban Mobility"


Mr. Qiaomu SHEN


Urban mobility indicates the patterns of human movement in cities. 
Mobility associated with rapid urbanization has received increased 
attention from various research fields. The study of mobility, which has a 
long history, benefits individual residents and city planners. Viable data 
from previous studies on mobility are greatly limited. With the 
development of sensing technologies, however, an increasing amount of data 
types can be collected to describe human movement and provide new 
opportunities to study mobility from different perspectives.

Numerous automatic methods have been proposed for the collection of 
mobility data. However, mobility patterns differ across time, space, and 
situations. This variability complicates the analysis of mobility data and 
requires the involvement of domain experts. Visual analytics bridge the 
gap between data analysis techniques and domain knowledge.

In this survey, we first introduce mobility visualization and its existing 
taxonomies. We then present a new taxonomy that classifies existing 
literature on the basis of data descriptions: spatial points, 
origin-destination, and trajectory. We further discussed the features, 
sub-classification, and applications of each classification. Finally, we 
provide insights on the future direction of mobility research.
