This study aims to prepare a green street planning strategy considering green street's urban temperature reduction function and contribute to efficiently alleviating urban heat stress. To this end, it intends to prepare the basis for a more efficient plan by deriving the surrounding factors that affect the street thermal environment. In addition, this study analyzes the limitations of the current green street planning system and derives the institutional basis for the green streets plan by examining related policy cases and the perception survey on pedestrians, which is the primary purpose of responding to heat waves in order to propose green street policy alternatives to respond to heat waves.
