One of the biggest challenges of the 21st century is to manage population growth and the resulting impacts. Population numbers that exceed the earth's carrying capacity are placing huge environmental pressures on the environment. This is not only reflected in waste management, energy consumption and the use of fossil fuels, but also in a deteriorating quality of life. The millions of people living in metropolises around the world, with their given road networks, create huge transport anomalies that need to be addressed at national and international level. Road congestion, drastic increases in journey times and the rising cost of travel have highlighted the importance of improving public transport. However, for public transport to be attractive, it is essential that the transport alternative itself is fast, comfortable and modern. In the present study, two metro construction projects in cities with high populations (Mumba, Ryadh) are examined, with particular attention to the scale of the project and its usability. The study aims to highlight the visible objectives expressed by the endusers and their reflection in the project based on the results of a primary survey in 2022 and a primary survey in 2023. We will focus on the different phases of project management that lead to the success of the project.
