In recent years, there are concerns about extreme weather events and large-scale earthquakes in Japan. In order to protect the lives and livelihood of each and every resident from such a variety of disasters, it is necessary to create an evacuation-ready environment based on accurate information. On the other hand, in the city where we live, streets that we use on a daily basis or streets where we have many friends often seem close, while lonely, dark streets or streets that we pass through for the first time often seem long and far away. This is called psychological distance in cognitive space, and it is thought to have a significant effect on evacuation, especially in times of panic.
Based on the results of previous studies, this study aims to create a topological and areal hazard map that is easier to evacuate by clarifying and describing factors such as traffic time periods and walking constraints that have been extracted as possible influences on spatial perception distance during evacuation, in order to create a topological and areal hazard map that is different from the previous ones. The final objective of the project is to create topological and areal hazard maps for real urban spaces. This will be useful for unprecedented evacuation planning in an aging society, and at the same time, it will lead to proposals for soft measures that are often lacking, such as the implementation of evacuation drills in the future. In this study, we will clarify the survey plan and contents for obtaining spatial cognition data, and the differences in spatial cognition according to developmental stages.
The results are highly distorted in the area around the train station, suggesting that there may be some element of concern on the straight road to the station. The results were also significantly skewed in areas where there are many supermarkets and restaurants. It is possible that the areas are recognized as short areas.
