Climate change and energy security are key issues for the transport sector in metropolitan cities in the 21st century. Cities are responsible for three quarters of global energy consumption and energy demands are driven in particular by increased traffic generation. In developing countries, the use of individual motor vehicles is constantly increasing, the trend of urbanization and the growth of metropolitan cities create major problems. Motor vehicles have been at the forefront of urban mobility for many years in Turkey, as in the world examples, so urban and transportation planning studies have been based on the search for solutions to the problems brought about by increasing vehicle mobility. This model has been replaced by new urban mobility concepts and it is aimed to free the public space from vehicle traffic and to create living spaces for urban residents with a worldwide mobility-oriented urban development. On the other hand, with the Covid-19 pandemic process, important changes have emerged in the fields of human relations, work and education in terms of mobility in cities, and it is aimed to make arrangements for bicycle and pedestrian routes with decisions based on public transportation. With this; In order to promote sustainable urban mobility after the pandemic, urban motor vehicle traffic, exhaust gas emissions, traffic noise, etc. Accessibility away from negativities and improving the physical conditions of pedestrian walking areas have become important measures. During the epidemic, there was an increase in the preferences for autonomous vehicles, and a decrease in the use of public transportation vehicles, especially due to the fear of not providing social distance, but the importance of sustainable mobility, pedestrian transportation and accessibility at the neighborhood scale was understood In this study; urban space, mobility, change in mobility and its effect on urban space, the importance of sustainability approach and the literature on permanent urban transportation solutions has been researched. Examples from different cities of the world were given regarding the changing forms of mobility with the pandemic process, the importance of street spaces and precautions.. In this study; In the sustainability approach, the importance of urban space, mobility, change in mobility and its effect on urban space, which is emphasized again, the literature on permanent urban transportation solutions has been researched, and examples from different cities of the world regarding the changing forms of mobility with the pandemic process, the importance of street spaces and the precautions taken. In addition to this, mobility in Büyükada was researched, permanent and resilient regulation proposals based on urban sustainability principles were discussed.
