بررسی اثرات زمانی زیست محیطی در احساسات عابران پیاده ایمنی

Although plans are made with people as the target, plan-making processes in most instances are dominated by top-down approaches, giving very little regard to how people perceive or feel about the cities they live in. The perceptions urban areas trigger and how these cause behavioural changes reflect the implications of planning and decision-making upon them. Prior studies indicate that environmental factors can trigger affective reactions in people. Thus, throughout this study, it was attempted to understand how environmental factors affect University students' perceptions of safety, which were quantified on the basis of their arousal, i.e. the calmness or stress felt, and walking speeds. Data on arousal were captured in real-time by a technically-sound, low-cost device assembled using free and open source software and hardware. The study could demarcate and rank the areas perceived to be “safe” and “unsafe” by the University students in real-time using the assembled device and identify which environmental factors have the most significant influence on their perception of safety. This study introduces the chance to determine unconscious reactions of people by triangulating data gathered by several measurement techniques that are directly measured in the field, which can be served as useful inputs for urban planning. Furthermore, the study confirms the value of the real-time sensing device as a tool beyond traditional methods in understanding feelings of safety in environmental settings.
