This research investigates new approaches to improving the user experience within underground urban tunnels by emphasising the integration of functionality for all users while achieving landscape elements and environmental factors. The study aims to integrate tunnel design standards with artistic installations and lighting to transform underground tunnels into visually attractive and psychologically comfortable spaces. The Maadi Metro Tunnel in Cairo was chosen as an example for the study due to its pivotal location. The study has an interdisciplinary approach. Firstly, to determine the function and visual comfort of the tunnel, a questionnaire was conducted for the users at peak time to find out the problems related to the design needs and visual comfort, based on design standards. Secondly, the lighting, acoustic
comfort, and thermal comfort. It was evaluated using the Design Builder, DIAlux, and then a redesign was proposed to improve the design flaws that were inferred from the questionnaire and design standard, such as the materials used, the disabled and elderly needs, improving thermal comfort and lighting, and conducting a re-analysis of thermal comfort and lighting. To make sure it is achieved. Ultimately, it was determined that improving the function, visual and thermal
comfort could enhance the users' experience.
