Two types of methods are used to evaluate pedestrian comfort: pedestrian wind comfort and outdoor thermal comfort. To accurately ascertain the outdoor wind environment, wind speed is the only parameter considered. However, pedestrians may still feel discomfort when the perceived temperature is low, even though the wind comfort criterion has been satisfactorily fulfilled. The purpose of this study is, therefore, to investigate pedestrian comfort when the perceived temperature is low, especially in winter conditions. To achieve this, a pedestrian survey was conducted, and 588 respondents completed a questionnaire. The results show that pedestrians feel discomfort when the WCET (Wind Chill Equivalent Temperature) is low, with almost 40 percent of respondents answering that they feel discomfort in these conditions. In conclusion, the threshold wind speed of the winter season could be determined to be lower than that of the existing comfort criteria by applying the WCET.

When outdoor wind environments are designed by applying the same threshold wind speed every year, pedestrians come to feel the discomfort caused by the wind chill in winter. It is expected that the adoption of the WCET proposed in this study makes it possible to improve the existing wind comfort criteria by adjusting the reference wind speed, thus helping to prevent discomfort caused by comfortthe wind in winter. criteria by adjusting the reference wind speed, thus helping to prevent discomfort caused by the wind in winter.
