Dubai is now among a small group of global cities operating large-scale fully driverless metro networks, with the upcoming Gold Line set to significantly strengthen its position.
Dubai: Dubai’s planned Gold Line will add 42km to the emirate’s metro network, increasing the total length from 120km to 162km, according to the Roads and Transport Authority. The expansion will also raise the number of stations from 67 to 85, marking a 35 per cent increase in the overall network size.
Largest driverless networks
Among fully automated metro systems, Dubai is now among a select group of cities operating large-scale driverless metro networks.
The Riyadh Metro has a planned network length of 176km across six lines, making it the largest driverless metro system currently under rollout, according to official project data and regional transport reporting.
With the addition of the Gold Line, Dubai’s metro network will expand to 162km, narrowing the gap with the Riyadh Metro to just 14km.
Dubai Metro has operated as a fully automated system since its launch in 2009. Its Red Line, stretching 52km, was previously recognised by Guinness World Records as the world’s longest driverless metro line at the time of its opening.
World’s largest metro systems
Globally, metro networks vary significantly in size, with the largest systems concentrated in Asia.
The Shanghai Metro spans more than 800km, according to operator data and international transport rankings.
The Beijing Subway also exceeds 800km, based on official system figures.
The Guangzhou Metro extends beyond 600km, according to network operator disclosures.
These systems have expanded over several decades through multiple lines and phases, serving large metropolitan populations.
In comparison, Dubai Metro will reach 162km after the Gold Line, placing it below the world’s largest metro systems but within the range of mid-sized urban networks.
Asia’s dominance in metro expansions
Asia accounts for the majority of global metro expansion, with several cities in China, Japan, and India operating networks exceeding 300km, according to international transport bodies such as the International Association of Public Transport.
Metro development across these regions is largely driven by high population density and urban scale, with continuous additions of new lines and network extensions.
Europe and North America metros
Metro systems across Europe and North America are typically older and more established, with slower rates of expansion compared to Asia.
The London Underground spans approximately 400km of route length, according to Transport for London.
The New York City Subway covers around 380km, based on data from the Metropolitan Transportation Authority.
The Paris Métro extends approximately 225km, according to figures from RATP Group.
These systems remain among the most heavily used in the world, but their expansion tends to be more gradual compared with newer metro networks across Asia.
How Dubai’s metro stands out
Dubai Metro stands out for being fully automated across all lines, a feature that remains uncommon among larger global metro systems.
The current network includes:
- Red Line: 52km, 28 stations
- Green Line: 23km, 18 stations
- Route 2020: 15km, 7 stations
With the Blue Line under construction (30km, 14 stations) and the planned Gold Line, the network will expand to 162km and 85 stations, according to the Roads and Transport Authority.
Varying ridership and demand
Dubai Metro currently serves around one million passengers daily, accounting for approximately 40 per cent of public transport use in the emirate, according to Roads and Transport Authority data.
Since its launch in 2009, the system has carried more than 2.8 billion passengers, including 295 million in 2025, marking a 7 per cent increase compared with 2024.
By comparison, metro systems in cities such as Tokyo, Beijing, and Shanghai handle several million passengers each day, reflecting differences in both network size and population.
According to the RTA, the line is expected to:
- Reduce congestion on a key Red Line segment by 23 per cent
- Remove more than 40 million road journeys annually
- Carry up to 465,000 passengers daily by 2040
This approach differs from the large-scale expansions seen in major Asian cities, where new metro lines often extend coverage across much wider urban regions.
