Kuala Lumpur, the vibrant capital of Malaysia, has undergone significant transformations in its transportation infrastructure since 2010. These developments aim to address the city's growing population, alleviate traffic congestion, and promote sustainable urban mobility. This article examines the evolution of Kuala Lumpur's transport system over the past decade and a half, highlighting key improvements, statistical insights, and critical evaluations of their impact.
Historical Context

Prior to 2010, Kuala Lumpur's transportation network was characterised by heavy reliance on private vehicles, leading to severe traffic congestion and environmental concerns. Public transport options were limited, and the existing systems struggled to meet the demands of the city's expanding populace. Recognising the need for a comprehensive and efficient transport system, Malaysian authorities initiated several projects aimed at enhancing public transportation and reducing the city's dependence on private cars.
Rail Network Expansion

Improving Urban Transport in Kuala Lumpur
Rail Network Expansion
A major part of Kuala Lumpur’s transport improvement strategy has been expanding the rail network to reduce congestion and improve accessibility. The Mass Rapid Transit (MRT) system was introduced to offer high-capacity public transport. The Kajang Line, opened in 2017, stretches 51 km and connects suburbs like Sungai Buloh and Kajang through the city centre. In 2023, the new Putrajaya Line began operations, linking Kuala Lumpur to the administrative capital. This line saw a rise in daily passengers from around 122,000 in October to nearly 128,000 in November 2023.
The Light Rail Transit (LRT) system also expanded. The Kelana Jaya Line added new trains under the KLAV27 project, improving frequency to every three minutes during peak hours.
The Monorail, which has operated since 2003, was upgraded to boost efficiency, especially for short-distance travel within the central business district.
Bus Services
Bus transport has also improved. Rapid Bus Sdn Bhd increased its daily fleet from 762 to 1,000 buses by the end of 2023. A pilot bus lane on Jalan Ampang, introduced in July 2023, led to a 15% rise in ridership. Real-time tracking through apps like Moovit has also helped passengers plan better and reduced waiting times.
Integrated Transport Hubs
To make it easier to switch between different transport types, integrated hubs like KL Sentral have been developed. KL Sentral connects MRT, LRT, KTM Komuter trains, and the airport rail link. Since opening in 2001, it has helped create a more connected and efficient transport system.
The SMART Tunnel
Kuala Lumpur also developed an innovative solution called the SMART Tunnel, which handles both road traffic and stormwater. Since 2007, it has helped prevent flash floods and improved traffic flow during heavy rain.
Trends in RidershipThanks to these improvements, public transport use has increased. By November 2023, over 1.1 million people were using public transport daily. Rail services (LRT, MRT, Monorail) carried over 835,000 passengers per day, while buses served about 259,000.
Challenges and Areas for Improvement
Despite progress, some challenges remain:
Last-mile connectivity: It's still hard for many people to reach their final destination from train or bus stations. More feeder services and better walking infrastructure are needed.
Service reliability: Overcrowding and delays still occur, especially during peak times.
Accessibility and awareness: Not everyone knows about or can easily access public transport options. More promotion and inclusive design could help.
Environmental impact: While public transport reduces emissions, more can be done—such as using electric buses and incorporating green spaces around stations.
Working towards further improvement
Since 2010, Kuala Lumpur has made major strides in transforming its urban transport system to address growing concerns over congestion, pollution, and accessibility. The expansion of rail lines, including the MRT and LRT networks, has increased coverage and provided commuters with efficient alternatives to private vehicles. The integration of services at major hubs such as KL Sentral has improved connectivity between different modes of transport, while innovations like the SMART Tunnel demonstrate how infrastructure can be designed to serve dual purposes—managing both traffic and flood risk.
These developments have contributed to higher public transport ridership, reduced pressure on road networks, and supported the city’s move toward more sustainable urban mobility. However, several challenges remain. Last-mile connectivity continues to limit the effectiveness of the transport network, especially for those living or working beyond walking distance from stations. Overcrowding and occasional service disruptions also reduce user satisfaction and discourage regular use. Additionally, while the system has begun addressing environmental goals, further steps—such as expanding electric bus fleets and improving pedestrian access—are needed to reduce Kuala Lumpur’s carbon footprint.
To build on its progress, Kuala Lumpur must prioritise inclusive planning, regular maintenance, and sustainable innovation to create a truly accessible, efficient, and eco-friendly transport system for the future.
