The research method in this study, based on theoretical studies and reviews examples of successful global promotion of walking in the historical tissues to analyze the historical context of Tehran's region 12. The results indicate that increasing density, fine grain, mixed-use retail, pedestrian design details and reducing lane width help to reinforce the walking trails in the historical context.
