Abstract

With the acceleration of urbanization, the microclimatic environment of street spaces has an increasingly significant impact on urban residents’ quality of life. This study conducted field measurements in the Seomyeon area of Busan to investigate the microclimate characteristics of street spaces during summer periods. Results showed that the microclimate in street spaces differ significantly from weather station data, with measured air temperature (TA) being 2.8℃ higher and relative humidity (RH) approximately 17.7 percentage points lower during noon hours. Different street orientations exhibited varying microclimate characteristics, with NS street recording the highest average TA (35.1℃) during 13:00-14:00, while SENW street showed the lowest (33.8℃). These TA variations were primarily influenced by urban morphological features such as building height, street width, and vegetation coverage, rather than street orientation alone. Street trees demonstrated positive effects on improving the microclimate, particularly in modifying wind environment, creating wind velocity (WVEL) differences of 0.3-0.4 m/s in certain street orientations. In addition, this study can serve as baseline data for urban street space planning and microclimate improvement.
