Purpose
The Doha Metro was developed as a flagship national infrastructure project aligned with Qatar National Vision 2030, aimed at transforming urban mobility in Doha. It reduces traffic congestion, supports sustainable transportation, and connects key economic zones, residential districts, and major venues such as stadiums used during the FIFA World Cup 2022. The system is designed to position Qatar as a global leader in smart urban transit, while improving connectivity, reducing carbon emissions, and enabling long-term economic growth through modern public transport infrastructure.
