🏘️ Good morning! Ari resident Harmish Muszid went from avoiding his neighbors to creating a project to connect a community through its layered past. Read the story here.
🔥 Soiciety is hosting a fire safety walk in Ratchathewi on Saturday, Oct. 10. We’ll cover the city’s firefighting gaps: stalled fire stations, narrow sois, a nightlife loophole and the divide between registered and unregistered communities. RSVP here.
🛣️ From the Main Road:
ONE BIG NUMBER
🛢️ 22,000

Crews pumped more than 22,000 liters of leaked fuel from drainage pipes under Rama III Road near the Khlong Toei and Yan Nawa border last week.
Why it matters: The Pollution Control Department on Thursday found air inside the drainage pipes thick with fuel vapor and nearing ignition, posing a fire risk.
Yes, but… Gov. Chadchart Sittipunt said the fuel hasn’t reached public waterways. Officials haven’t ordered evacuation, though nearby residents have reported ongoing fuel smells.
What’s next: Line operator BAFS Pipeline Transportation said it’s cooperating with the investigation and will cover damages if found responsible. Repairs should take about five days.
INFRASTRUCTURE
1. 🚶 Data disputes 2024 Phrom Chit lane removal

A new preprint paper finds traffic data contradicts Bangkok’s 2024 removal of a 250-meter protected bike and pedestrian lane in Soi Phrom Chit, pulled within a day of installation over reported “severe congestion.”
Why it matters: The paper argues officials yielded to drivers’ complaints rather than collecting performance data, which reflects a pattern of prioritizing cars in a multimodal city.
Flashback: Officials installed bollards in the Sukhumvit 39 sub-soi in 2024, converting one of two lanes for non-motorists. It sparked immediate pushback, with FM 91 airing complaints about congestion. The city removed the lane by 10 p.m. the same night.
State of play: Researchers — including one tied to the group behind the pilot — analyzed 692,313 Muvmi fleet GPS data points in the soi and 14.2 million nearby and found traffic speeds mostly stayed within normal ranges on launch day.
Yes, but… The exception was a 90-minute midday slowdown that resolved by 2 p.m. — two hours before city officials held an emergency meeting on the lane removal, according to the paper.
The evening congestion blamed on the lane started on surrounding main roads and spread into the soi, the paper states.
Between the lines: Cars account for 35% of daily trips in Bangkok, while walking, cycling and public transit make up 65%, according to the Thailand Walking and Cycling Institute Foundation.
The quote: “A street that moves 200 pedestrians per minute and 30 cars per minute is not a congested street,” researchers wrote, “it’s a street whose performance is being measured by the wrong metric.”
What’s next: Researchers recommend future pilots run for at least four weeks with pre-set criteria. They also urge the city and traffic media to report street conditions for all users beyond drivers.
TRANSPORTATION
2. 🚇 Airport Link’s price to keep running

Asia Era One offered to keep running the Airport Rail Link for four more months if the state pays 240 million baht and shields it from lawsuits tied to the high-speed rail project it intends to exit. The SRT has rejected both conditions.
Why it matters: The operator plans to end service when its contract expires Sept. 30. The rail deal is part of the three-airport, high-speed rail project.
What’s next: If talks fail, the SRT says its subsidiary will take over the line, backed by extra trains on the eastern suburban route.
Zooming out: Maintenance issues had dragged headways to 15 to 30 minutes, stranding crowds on platforms. Only five of the line’s nine trains are operational.

PUBLIC SAFETY
4. 👨🚒 Firefighting budget adds a robot

Bangkok’s preliminarily approved 2027 budget includes the city’s first firefighting robot, slated for Phaya Thai Fire Station.
Why it matters: Budget documents say the robot would handle firefighting, rescues, fire prevention checks and animal removals.
Zooming in: The Fire and Rescue Department’s director said the chemical-resistant robot, capable of carrying 20 kilograms of hoses, could have helped fight a 2025 Lat Krabang warehouse fire that took three days to control.
Zooming out: The purchase aligns with Gov. Chadchart Sittipunt’s re-election promise to bring in new firefighting technology, like drones for high-rises.
Between the lines: The 3.77 million baht robot will be in Phaya Thai for quick access to the Sirat Expressway. A similar proposal for the Thonburi side was cut.
GOVERNANCE
5. 📑 Building permits top city’s corruption complaints

Bangkok logged more than 16,000 corruption reports via its tip line in the past four years, with construction permits fraud making up the largest category, Gov. Chadchart Sittipunt said.
Why it matters: Chadchart said permit approvals rely heavily on discretion, creating room for bribery. Consumer groups have repeatedly flagged the resulting safety risks.
What’s next: The city plans to move permit applications fully online to reduce face-to-face interactions and close loopholes.
