WithE.N. Sari, S. Yilmaz, B.G. Yilmaz

In livable cities; the street is defined as the first encounter area when going from private to public space. It is the core area that will contribute to increase the quality of life in the city. In this sense, the street must meet the basic criteria for providing a comfortable living environment to urban users. In the scope of the study, an attempt was made to define pedestrian-friendly street parameters including the air quality and thermal comfort. Therefore, a microclimate data of the city center streets were hourly collected 1.5 m above the ground level in winter period of 2017. Then a different landscape design scenarios in pedestrian streets was investigated widely using Envi-met model to determine the thermal comfort level by measuring the predicted mean vote index (PMV). The result shows that, the scenario of deciduous trees was found to have higher thermal comfort than treeless street design for pedestrian-friendly streets. The study aims to fill the gap in the literature by taking the street ecology which is neglected in the user-friendly street works and by showing the pedestrian-friendly street parameters that are physically and ecologically meaningful This result coincides with the physical parameters and necessitates the revision of the vegetation arrangement once more. When thermal comfort and the air quality are taken into account, it is understood that streching the principles is a necessity in order to obtain a sustainable street design. The outputs of this study will help to improve the outdoor thermal comfort in first stage of the urban planning and landscape street design for more livable effective city.
