A researcher conducted a covert, non-participant observation to investigate pedestrian risk-taking behaviors (specifically, mobile phone distractions while crossing roads) in different urban environments. The observation took place at three distinct locations: a busy pedestrian crossing outside a financial district, a crossing directly outside a secondary school during home-time, and a suburban crossing near a retirement village. The sample consisted of members of the public who happened to cross the road at these locations during the designated observation windows. The researcher recorded behaviors such as crossing while typing on a smartphone, crossing while wearing headphones without screen use, and crossing with no visual devices.
