Claims, one by one

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-265463207cb2084e descriptive
World Bank-funded CASE project
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The World Bank's completion report covers the Clean Air and Sustainable Environment (CASE) project, financed by an IDA credit; The Business Standard names CASE as the project behind the automatic signals.
Caveat
The World Bank money was a concessional credit to the government, not a grant.

Sources carrying this claim

  1. World Bank — CASE Project completion report (authority)
  2. The Business Standard (press)
Claim 2 clm-a820434a34f0e696 quantitative
put new automated signals at 29 intersections and repaired others
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The World Bank report counts "new traffic signals installed at 29 intersections" and 91 intersections with operational signals "including newly installed and existing fixed". New Age reports 29 new signals installed under CASE alongside timers and solar panels at 70 crossings.
Caveat
The Business Standard gives a different count — 100 automatic signal systems — so counts vary by what each source includes.

  1. World Bank — CASE Project completion report (authority)
  2. New Age (press)
Claim 3 clm-e2da0a91ec4908d7 quantitative
some Tk112 crore went into lights and intersection works between 2010 and 2018
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The Daily Star: "Tk 112 crore funded by the WB were spent between 2010 and 2018 for repairing and installing 100 traffic lights and other intersection infrastructure."
Caveat
The Business Standard puts the cost of the CASE signals at about Tk100 crore; the figure covers more than the 29 new signals.

Claim 4 clm-1001043503b8619c descriptive
but the systems went largely unused as police kept directing traffic by hand
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The Daily Star (2020) found the World Bank-funded lights "serve only decorative purposes" because traffic is controlled by police hand gestures; the 2022 article reports that the trial run failed and traffic police returned to manual control; The Business Standard (2025) says that except at Gulshan-2 the automatic signals are not operational anywhere.
Caveat
No claim-specific caveat recorded

Claim 5 clm-16fe619832091ca2 quantitative
A successor semi-automatic system — funded by the two city corporations and engineered by BUET — went live at seven intersections on 30 August 2025.
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The Business Standard reports the DTCA announcement that the semi-automatic system launches at seven intersections on 30 August, "financed by the Dhaka North and South city corporations, with technical support from Buet". The Daily Star (March 2026) confirms the inauguration at seven intersections on 30 August 2025.

  2. The Daily Star — Pilot project shows promise, but delays stall wider rollout
Claim 6 clm-1774ebaaa8729b15 quantitative
The automated signals at 29 intersections went largely unused, with police continuing to direct traffic by hand.
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The Daily Star (2020) describes police hand gestures overriding the World Bank-funded lights; The Business Standard (2025) says the CASE signals are not operational except at Gulshan-2; New Age reports that police handle the signals by hand.

Claim 7 clm-cb880c3fe42fe318 quantitative
The World Bank's completion report of September 2019 had recorded the 29 intersections as installed and operational, and a 9.5 percent increase in vehicular traffic through selected signalised intersections.
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The report's results table lists "Intersections with new traffic signals installed and operational" as 29 against a revised target of 29, and states that vehicular traffic at selected intersections with operational signals "exceeded the target of 8 percent to reach 9.5 percent by end of project".
Caveat
This is the funder's own completion reporting, written at project close; the same report notes that the signals' performance had not stabilised and that the police were still taking them over.

Claim 8 clm-0927259ca5707cb3 quantitative
A Daily Star reporter who visited at least 30 intersections found the lights working at only six (January 2020).
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The Daily Star: "Visiting at least 30 intersections in the capital recently, this correspondent found that the lights were working only at six."
Caveat
A reporter's site visits, not a systematic survey.

Claim 9 clm-5dea86a9a1910080 quantitative
In February 2025 The Business Standard reported that, except at the Gulshan-2 intersection, the CASE signals were not operational anywhere, citing a government impact evaluation (IMED, 2022-23) that called the money spent a complete waste.
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The Business Standard: "Except for the Gulshan-2 intersection, these automatic signal systems are not operational anywhere else", and "The money spent on this has been a complete waste according to the IMED report", referring to the Implementation Monitoring and Evaluation Division's Impact Evaluation Report (2022-23).
Caveat
The IMED evaluation is known here only through the newspaper's account.

mapped · no interpretation or interpolation added by this file
What the mapping says

Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The World Bank report says Dhaka Metropolitan Police "required a significant amount of capacity building" to manage the signals and that a fragmented mandate between city and police persisted throughout; The Daily Star (2020) quotes officials that the police lacked monitoring and maintenance capacity and a traffic inspector explaining why the automatic timings were overridden; the 2022 article reports police reverting to manual control.

Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says

The World Bank's Implementation Completion and Results Report on the Clean Air and Sustainable Environment (CASE) project: a US$62.2 million IDA credit plus US$35 million additional financing, closed 31 March 2019. It records new traffic signals at 29 intersections and 91 intersections with operational signals, reports a 9.5 percent increase in vehicular traffic at selected signalised intersections, and describes the slow handover of the signals to Dhaka Metropolitan Police (29 intersections by 31 August 2019).

Says CASE ran from 2009 to 2019 under the Department of Environment, the city corporations and DTCA, and installed 100 automatic traffic signal systems for about Tk100 crore; except at Gulshan-2, none is operational. Cites the Implementation Monitoring and Evaluation Division's impact evaluation report (2022-23), which found the automatic system ineffective and the money a complete waste.

Seven months after the 30 August 2025 inauguration, traffic flows better at the seven equipped intersections but drivers still run reds; signals at the other 15 pilot intersections were not yet installed because of procurement and administrative delays (BUET's Prof Moazzem Hossain).
