Manila's Duplicate Sign Problem: How the City Stacks Up Against Bangkok, Bogotá, and Beyond

Drive along EDSA between Guadalupe and Ortigas any weekday morning and you will pass the same billboard-sized regulatory sign at least three times within 500 meters. Nobody ordered the duplicates removed. Nobody budgeted for the audit. The signs just accumulated, layer by layer, agency by agency, over years of uncoordinated urban administration — and Metro Manila is now confronting the cost of that neglect.

The issue of duplicate image replacement — the systematic identification and removal of redundant public signage, street markings, and visual information fixtures — has moved up the agenda at the Metropolitan Manila Development Authority after complaints from transport planners that conflicting or repeated signage is contributing to driver confusion on high-accident corridors. The timing matters: the Department of Transportation is currently revising its Road Safety Action Plan for 2026 to 2030, and signage rationalisation is listed as a reform area under the plan's urban corridor component.

The Problem on the Ground

Roxas Boulevard near the CCP Complex is one of the most documented cases. City engineers have identified stretches where three separate agencies — the MMDA, the Manila City government, and the Department of Public Works and Highways — have each installed their own version of the same speed limit or no-parking marker within a single block. The result is not just visual clutter. Transport researchers have noted that when drivers see the same instruction repeated inconsistently across multiple sign formats, compliance rates drop.

Quezon City has taken a more proactive position. The city's Public Works Department launched an inventory of all road signage along Commonwealth Avenue in the first quarter of 2026, covering the 12.7-kilometre stretch from Elliptical Road to Tandang Sora. The goal is to produce a single consolidated sign plan by October 2026 that eliminates redundant fixtures and standardises the remaining ones to Department of Public Works specifications. That programme has not yet been replicated by the City of Manila or Pasig.

The comparison with other cities in the region is instructive. Bangkok's Department of Traffic and Transportation completed a full signage audit of its inner-ring roads in 2024, removing more than 4,200 duplicate or conflicting signs as part of a World Bank-backed urban mobility grant. Bogotá, under its 2022 Movilidad Segura programme, similarly digitised its entire street sign inventory and flagged redundant markers through a GIS mapping system before crews physically replaced them. Both cities started with a centralised authority responsible for all public signage — something Metro Manila, with its 17 local government units each retaining concurrent jurisdiction over their own road infrastructure, structurally lacks.

What Other Cities Did Differently

The jurisdictional fragmentation is the core obstacle. In Kuala Lumpur, the city council holds singular authority over all signage within its boundaries, which allowed its 2023 signage rationalisation drive to proceed without inter-agency negotiations. Manila's setup means that even if the MMDA identifies a duplicate sign on a barangay road in Tondo, the physical removal requires coordination with the City of Manila engineering office, which may have installed the sign under a separate budget line.

Funding is the second gap. Bogotá allocated roughly USD 3.2 million to its 2022 signage audit and replacement programme, drawing partly on Inter-American Development Bank infrastructure funds. No comparable dedicated budget line has been publicly announced for Metro Manila's signage rationalisation efforts, though the MMDA's 2026 capital outlay appropriation does include a line item for traffic management infrastructure that could theoretically cover the work.

For commuters and local businesses, the practical advice is to report duplicate or conflicting signs through the MMDA's 136 hotline or through the agency's online traffic concern portal. The Quezon City Public Works Department has also opened a public comment period on its Commonwealth Avenue sign plan until August 15, 2026, accepting submissions at the district engineering office on BIR Road in Diliman. Anyone who travels those corridors daily and has documented specific problem spots — photographs with GPS coordinates carry the most weight — can submit them directly. Cities that solved this problem fastest were the ones where residents helped build the inventory first.
