Recently, urban temperatures are rising, requiring both mitigation and adaptation measures. This study focused on creating shade in downtown of Hiroshima City to understand pedestrian’s route choice tendencies. Results showed that half of the walking spaces lacked shade in the afternoon, requiring heat mitigation. The distribution of pedestrians differs by season, with a higher percentage of pedestrians on the north side of the wide streets in the fall and south side in the summer. The two distributions indicate that shade is needed in spaces where people stay and where pedestrian traffic is high, such as parks, plazas, and wide streets.
