     as shading, an important factor in urban environments, affects thermal environments and long-term thermal comfort, this study conducted several field experiments to analyze the outdoor thermal conditions on urban streets in central taiwan. the rayman model was utilized for predicting long-term thermal comfort using meteorological data for a 10-year period. analytical results indicate that slightly shaded areas typically have highly frequent hot conditions during summer, particularly at noon. however, highly shaded locations generally have a low physiologically equivalent temperature (pet) during winter. correlation analysis reveals that thermal comfort is best when a location is shaded during spring, summer, and autumn. during winter, low-shade conditions may contribute to the increase in solar radiation; thus, thermal comfort is improved when a location has little shade in winter. we suggest that a certain shading level is best for urban streets, and trees or shade devices should be used to improve the original thermal environment.
