You might have heard news about a traffic congestion charge and wondered what it is and how it affects us. Let’s break it down for you.

Recently, there’s been news that the Ministry of Transport is considering implementing a traffic congestion charge. The proposed fee starts at approximately 40–50 baht per vehicle in the first five years, with potential increases in the future. The initial trial areas are roads in the Sukhumvit-Silom zones, aiming to encourage public transport use, reduce pollution, and tackle PM 2.5 dust problems.

What is a Traffic Congestion Charge?

A congestion charge is a fee collected from drivers who enter areas with heavy traffic. Its main goals are to decrease the number of vehicles on the road, promote public transport usage, and reduce air pollution. Cities like London, New York, and Stockholm have successfully implemented this policy.

How Does It Work?

• Fee Zones: Typically areas with high traffic density, such as city centers.
• Timeframes: Fees are usually charged during peak hours, like morning and evening commutes.

Potential Locations in Thailand

A study by the Office of Transport and Traffic Policy and Planning (OTP) in collaboration with GIZ identified six major routes suitable for this policy, including:

• Petchaburi-Thonglor intersection (60,112 vehicles/day)
• Silom-Narathiwat intersection (62,453 vehicles/day)
• Sathorn-Narathiwat intersection (83,368 vehicles/day)

Benefits of a Congestion Charge

• Reducing Traffic: Encourages people to avoid driving in congested areas.
• Lower Air Pollution: Reduces greenhouse gas emissions and PM 2.5 levels.
• Promoting Public Transport: Encourages the use of trains, buses, and bicycles.
• Improved Road Efficiency: Less congestion means smoother traffic flow.
• Increased State Revenue: Funds can be used to improve infrastructure and transport.
• Enhanced Safety: Fewer cars on the road reduce accident risks.

A congestion charge is a promising tool to tackle urban traffic and pollution issues. However, careful planning and execution are essential to ensure maximum benefits and public acceptance.
