Scheduled city buses returned to Phnom Penh in 2014 under a new City Bus Authority. In July 2019 City Hall and JICA fitted buses with GPS and launched an official City Bus app showing vehicles in real time; the authority still maintains it. An airport express line opened in September 2025. Dedicated bus lanes remain a proposal.

Scale🏙️ City-wide

🎓 Lesson

Phnom Penh bought the cheap half first. Fitting buses with GPS and publishing their positions took one donor project; giving those buses a lane of their own was still only an instruction from the prime minister in 2024 — so the app can say where a bus is, but not make it any faster.

Evidence Passport · public beta 6 addressable claims, 7 source dossiers, one permanent baseline. The passport is unreviewed — an AI-assisted structural migration, not a human or expert endorsement. Every revision keeps a permanent copy under revision history.

Inspect the claims, one by one — verbatim text, sources and caveats for all 6

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-ac234a860bdf66f0 quantitative
Scheduled city buses returned to Phnom Penh in 2014 under a new City Bus Authority
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The article reports the city bus system fully opened to the public in late 2014, run by the City Bus Authority under the Phnom Penh Capital Administration with JICA support.
Caveat
The Phnom Penh Post blocks automated retrieval; the sentence was confirmed through search results rather than by opening the page.

Sources carrying this claim

Claim 2 clm-dddfdac021dffe47 quantitative
In July 2019 City Hall and JICA fitted buses with GPS and launched an official City Bus app showing vehicles in real time
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Khmer Times (8 July 2019) reports City Hall cooperating with JICA to install GPS on buses for the City Bus app; the App Store listing, published by the authority itself, describes 'real time bus location, all available routes, search a specific route, and bus stops'.
Caveat
No source states how many buses carry a working GPS unit today.

  2. City Bus Official App — Apple App Store (Phnom Penh City Bus Authority)
Claim 3 clm-9fdfde6fbae784ac descriptive
the authority still maintains it
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The App Store listing shows version 5.0.0 last updated 19 July 2025 with the authority as seller; the Play listing carries the same version under the government package id; and the operator-side management system still serves a working login.
Caveat
A maintained app and a live backend show the system is not abandoned; they do not show how well tracking works in the street — riders' public reviews report buses missing from the map.

What the mapping says
The Airport Express between Kouch Kanong roundabout and Techo International Airport started on 9 September 2025, operating 05:30–23:30 at the standard 1,500-riel fare.
Caveat

Claim 5 clm-2169474b0ed57a2e descriptive
Dedicated bus lanes remain a proposal
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
As of June 2024 no dedicated bus lanes had been built; the prime minister had instructed the capital administration to establish them, and the plan targeted ring roads and satellite cities rather than the existing network.
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. CamboJA News — Phnom Penh to incorporate dedicated bus lanes (18 June 2024)
Claim 6 clm-203ffa2325bc2b22 quantitative
giving those buses a lane of their own was still only an instruction from the prime minister in 2024
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Prime Minister Hun Manet instructed the Capital Administration to establish bus lanes on 18 June 2024, saying public transport 'must be given priority over private vehicles'; the article confirms none had been built.
Caveat
The instruction may have advanced since June 2024; no later source was found either way — re-check at the next verification pass.
