Summary of "LEAPING FORWARD IN GREEN TRANSPORT: THE CASE OF KOREA"

Core Content

This document explores how South Korea, particularly Seoul, transitioned from a traditional supply-side approach to urban transport to a more sustainable and integrated green transport model. It highlights the challenges of traffic congestion, air pollution, and the inefficiency of road expansion, and outlines the successful strategies that led to improved public transport usage and reduced environmental impact.

Main Points

• Urban Transport Challenges: Cities like Bangkok, Cairo, Lagos, Mumbai, and Nairobi face issues of traffic congestion, high GHG emissions, and air pollution due to economic growth attracting more people and vehicles. Seoul was no exception, experiencing a sharp rise in car ownership and traffic problems in the 1980s and 1990s.

• Historical Context: After the Korean War, the government focused on road and metro expansion to support economic recovery. However, this led to a vicious cycle where road expansion failed to alleviate congestion and instead worsened it, with congestion costs rising to 3.6% of GDP by 1997.

• Shift to Green Transport: Seoul's decision to demolish the Cheonggyecheon expressway in 2002 marked a turning point. The city shifted to a demand-side, green transport strategy, emphasizing public transit over road expansion.

• Integrated Transport System: The reform in 2004 introduced a multimodal transport system with integrated bus and metro services, free transfers, and distance-based fares. This system improved travel reliability, reduced accidents, and increased public transport usage.

• Technological Innovation: The use of information and communication technology (ICT) was pivotal. The transportation smart card (T-card) enabled a seamless, distance-based fare system with real-time information and efficient revenue distribution.

• Economic and Environmental Benefits: The reforms led to a significant increase in public transport ridership, a decrease in congestion costs, and a reduction in CO₂ emissions and air pollution. Seoul's modal share of public transport reached over 60%, surpassing that of Beijing, Singapore, and Tokyo.

Key Information

1. Road Expansion and Its Limitations

• From 1980 to 2010, Korea's total road length more than doubled.
• By 2000, Seoul's road density was significantly higher than Beijing and Shanghai.
• Congestion costs rose to 3.6% of GDP by 1997, with Seoul accounting for a large portion.
• The Cheonggyecheon expressway, once a symbol of development, became a major source of congestion and pollution, leading to its demolition.

2. Public Transport Reforms

• Transit-Oriented Development (TOD): New towns and satellite cities were developed with integrated transport systems, centered around metro and BRT stations.
• Fare System: Introduced a distance-based, free-transfer fare system that reduced travel costs and encouraged transfers between modes.
• Bus Route Simplification: Routes were reorganized into a trunk and feeder system, improving accessibility and convenience.
• Community Shuttle Buses: Small buses connect remote areas to main transit hubs, serving all parts of the city, including poorer neighborhoods.

3. ICT Integration

• Smart Card System (T-card): Enabled distance-based fares, free transfers, and real-time information.
• Revenue Distribution: Based on distance traveled, ensuring fair compensation for bus companies.
• GPS Tracking: Improved service monitoring and passenger information, contributing to the efficiency of the transport network.

4. Outcomes and Impact

• Passenger Satisfaction: Increased from 4.85 to 7.5 within a year of the reform.
• Accident Reduction: Bus-related accidents and injuries decreased by 25%.
• Congestion and Emissions: Congestion costs declined, and CO₂ emissions were kept under control.
• Social and Economic Gains: The reforms brought significant social benefits, including reduced travel time, lower costs, and improved air quality.

Conclusion

Korea's green transport transition was driven by strong political will, innovative policies, and the integration of multimodal transport with ICT. The shift from road-centric to transit-oriented development has not only improved urban mobility but also contributed to environmental sustainability and economic growth. Seoul's experience serves as a model for other cities seeking to balance urban development with green growth.
