The development of modern cities is growing rapidly. The first thing that can be recognized in the current image of the complex and chaotic urban city environment is the deprivation of pedestrian space due to the rapid growth of pathways for automobiles. Pedestrians became secondary to automobiles. Therefore, to offer the comfort and convenience of city life and bring vitality to the external environment, pedestrian-only space will be needed; not the space with strong exclusion of pedestrian rights over the current industrialized urban environment but the space with emphasis in terms of pedestrian walks. In other words, the space design for the pedestrians is urgently needed and it has to be developed through extensive studies. Therefore, this paper is based on the possibilities of pedestrian space that can promote urban activities. It is dealt with the general theories, traffic problems, environmental problems and historical space development. In addition, the current pedestrian conditions in domestic pedestrian-only roads and the examples of the streets that have no cars will be presented; both domestic and foreign. By observation of the pedestrian-only roads, the feasibility of pedestrian-only road and potential capability will be discussed Improvements in the street without cars can provide directions for future development.
