  Non-motorized transport is becoming increasingly important in urban
development of cities in China. How to evaluate the non-motorized transport
popularity of urban roads is an interesting question to study. The great amount
of tracking data generated by smart mobile devices give us opportunities to
solve this problem. This study aims to provide a data driven method for
evaluating the popularity (walkability and bikeability) of urban non-motorized
transport system. This paper defines a p-index to evaluate the popular degree
of road segments which is based on the cycling, running, and walking GPS track
data from outdoor activities logging applications. According to the p-index
definition, this paper evaluates the non-motorized transport popularity of
urban area in Wuhan city within different temporal periods.
