Abstract:
Urban parks can offer both physical and psychological health benefits to each individual urban dweller and provide social, economic, and environmental benefits to society. Earlier researchers rely on distance or walking time from the home as the single most important precondition for use of green spaces to delineate urban park service areas. These catchment areas are based on the assumption that people are using the closest parks that they have access to. However, actual service areas can be affected by many other factors such as social capital cultivation, cultural adaptation, climate and seasonal variation, and park function and facilities provided, etc. The actual service areas are difficult to measure with tracking devices and individual travel-activity data. Since the turn of the millennium, the emergence of big data provides inspiring potentials to examine urban mobility at low cost and a large scale such as social media and crowdsourcing data, Internet of Things, traffic and vehicular data, and mobile application data. This research addressed the research gap of using mobile application data to delineate urban park service area. The study area is the 23 special wards of Tokyo or tokubetsu-ku, the core of the capital of Japan. Mobile data involving over 1 million phone location data collected in 2011. The results show that (1) park service areas vary significantly by park surface areas; (2) seasonal variation exist for large scale parks; (3) people do use smaller parks nearby but also travel a longer distance to large parks.
