However, the development that has been carried out is considered not able to create a comfortable climate for pedestrians due to high regional temperatures, especially during the day. For this reason, this study aims to examine how to create a comfortable pedestrian ways to climate change, especially in the Old City Region of Semarang. The method used in the form of analysis of the level of thermal comfort using the ArcGIS application and pedestrian ways analysis using vegetation distribution and building shadow analysis.
