Title: Equity of environmental exposure during mobility, a Big Data approach
12. Matemaattis-luonnontieteellinen tiedekunta
EXAMINING EXPOSURES
WHILE ON THE MOVE
• Traditionally, the analyses on environmental exposure have
mostly been static and based on home locations
• Environmental exposures during mobility has been emerging in
the research agenda
• Most concentrate on air pollution. Noise, heat, greenery much
less studied. Combinations are almost non existing.
• Many of the studies are motivated by the promise of health and
well-being benefits among population
• Behaviour vs. environment is important to understand:
e.g. Sarkar et al. (2015) found significant associations between
the odds of walking and the density of street trees.

DIFFERENT MOBILITY
PARAMETERS
• Xu et al (2019) used mobile phone data as they had call detail
records (CDR) and data detail records (DDR) from 100 000
active users.
• Woodcock et al. (2014) used 12-months of bicycle-sharing data
from London to reveal actual mobility behaviour by the users
and to study system’s health impacts.
• Lee & Sener (2019) on cyclists’ exposure to air pollution with
data from Strava sports application. Strava data was also used
by Sun & Mobasheri (2017) who studied the exposure of
commuting and non-commuting cyclist.
• In a study by Apparicio (2018) participants carried a single or
multiple sensors while travelling.
