Creating and comparing activity space measures to understand how walkability, urban sprawl, and public transit accessibility are associated with location based physical activity in 4 Canadian cities
Understanding how individuals interact with their cities, how they move through their environments, and how characteristics of the urban environments like walkability, sprawl, and how public transit can change physical activity behaviour are important public health objectives. Technological innovations in using smartphones allow researchers to collect highly detailed location and physical activity data using global positioning systems (GPS), cell phone towers, and accelerometers. However, there are still important challenges in making the best use of the large amounts of data researchers can collect from smartphones. Our team will work to develop new measures to understand how we can better use smartphone data to understand how the way people move in cities might influence their physical activity.
