Traffy Fondue: Bangkok's LINE-Based Problem Reporting

Bangkok residents photograph a broken pavement, a blocked drain or a dead streetlight inside LINE, the messaging app most Thais use. NECTEC, Thailand's national electronics research centre, built the Traffy Fondue platform in 2017; the Bangkok Metropolitan Administration launched it citywide on 31 May 2022, days after Chadchart Sittipunt won the governorship. Geotagged reports go to the responsible district office, their status is public, and since 2024 an AI layer classifies them. City councillors have warned that tickets get closed to protect departmental scores, and reports needing agencies outside the BMA stall.

📊 Impact

1,229,503 reports received and 1,000,113 resolved (81%) as of 4 March 2026, on the city's own figures; the city says routine cases now close in one to three days. At the April 2024 council session the split was 79% resolved, 17% forwarded to agencies outside the BMA and 2% still pending inside BMA departments.

🎓 Lesson

Routing is the easy part. A closed ticket records that an office responded, not that the problem stayed fixed.

Sources

↗ Frontiers in Sustainable Cities — Traffy Fondue: a smart city citizen engagement platformPeer-reviewed. Gives the Bangkok launch date of 31 May 2022 and more than 1,700 reports on day one, describes the workflow engine that pushes each case to the responsible agency, and the AI engine that sorts reports into 24 predefined categories. Its own volume figures stop at October 2022, so it does not carry the impact numbers used here.
↗ Bangkok Metropolitan Administration — one million cases resolved (4 March 2026)The city's own PR channel and source of the current volumes: 1,229,503 reports, 1,000,113 resolved (81%), 81% satisfaction among resolved cases, and the claim that common problems close within one to three days.
↗ Bangkok Metropolitan Council — questions to the governor on Traffy Fondue (24 April 2024)Official council record and the entry's counterweight: 563,292 reports, 444,223 resolved (79%), 96,811 (17%) forwarded outside the BMA, 10,397 (2%) pending; a councillor's concerns about false complaints, repeat reports caused by slow fixes, and cases closed to protect departmental performance scores.
↗ NECTEC — managing city and community problems with the Traffy Fondue platformThai primary source from the builder. Dates the platform's development to 2017, describes its AI, big-data and chatbot components, and the September 2019 Interior Ministry agreement to roll it out nationwide, establishing that NECTEC built it well before the BMA adopted it.
↗ Thai Post — new AI features in Traffy Fondue (21 July 2024)Confirms the AI layer is deployed rather than a research claim: it summarises reports, classifies the problem type from text and images, prioritises, and identifies the responsible agency, cutting reporting from five steps to three. Also notes the platform is used by more than 15,000 Thai organisations beyond Bangkok.
↗ Bangkok Post — Traffy Fondue app no magic cure-all for city illsIndependent press counterweight: the platform performs on problems inside a single district's authority but slows when several agencies are involved, and quick responses do not always produce lasting fixes. Site blocks automated fetching; content confirmed via search and used only qualitatively.
↗ Open Government Data of Bangkok — Traffy Fondue complaint statisticsShows the city publishes Traffy Fondue complaint statistics as an open dataset, supporting the public-visibility claim.
