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.

↗ 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 resolvedPublished 9 March 2026The 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.

↗ NECTEC — managing city and community problems with the Traffy Fondue platformPublished 28 June 2021Thai 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.

Claim 1 clm-c6012866d6f95808 quantitative

Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The builder's own page dates the platform's development to 2017 and records a September 2019 agreement with the interior ministry to roll it out nationwide, establishing that it existed well before the city adopted it. The peer-reviewed account gives the Bangkok launch date of 31 May 2022 and more than 1,700 reports on day one.

  2. Frontiers in Sustainable Cities — Traffy Fondue: a smart city citizen engagement platform

snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The peer-reviewed account describes the workflow engine pushing each case to the responsible agency and an AI engine sorting reports into 24 predefined categories. The July 2024 report 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. The city publishes complaint statistics as an open dataset, which supports the public-visibility half.
Caveat
The same 2024 report notes the platform is used by more than 15,000 Thai organisations beyond Bangkok — it is not a Bangkok-only system.

Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The official council record carries a councillor's concerns about false complaints, repeat reports caused by slow fixes, and cases closed to protect departmental performance scores, alongside the finding that 17 per cent of reports had been forwarded to agencies outside the city administration. The independent press account makes the same structural point: 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.
Caveat
The press page blocks automated fetching; its content was confirmed via search and is used only qualitatively.

The city's own channel gives 1,229,503 reports, 1,000,113 resolved at 81 per cent, 81 per cent satisfaction among resolved cases, and the claim that common problems close within one to three days.

City self-report, labelled as such in the entry. Resolution here means a case marked closed.

Caveat
The legislature putting the executive's own numbers on the record, which is why this is the entry's counterweight to the city's later headline figure.
