Dubai Metro (2009)
Dubai opened the first driverless metro in the Middle East, with Red and Green lines spanning the city. It later added the Route 2020 extension to serve the Expo 2020 site.
The metro became a backbone of Dubai's public transit, carrying hundreds of millions of passengers annually.
It set the regional standard for automated urban rail and demonstrated how Gulf cities use metros to support mega-events.
Dubai's Route 2020 extension served a world expo, the same role Riyadh's Yellow Line will play for Expo 2030.
