Accra

Every editorial link from Accra's entries into another city, strongest first. Each one is a statement about two projects, not about two cities — the three above are the ones the atlas is willing to make at city level.

• 🇰🇪 Nairobi: Digital Matatus Open Mapping Framework Same technique, opposite afterlife: Nairobi's feed is still maintained; Accra's stopped when the consultants left.
• 🇰🇪 Nairobi: Map Kibera — Residents Surveying an Informal Settlement into OpenStreetMap Residents mapping their own settlement in 2009 against a donor flood-risk programme in 2018 - both end with data nobody must act on.
• 🇳🇬 Lagos: Lagos State Parametric Flood Insurance Policy Two ways to spend donor money on the same hazard: map the floodplain, or buy an automatic payout against it.
• 🇮🇩 Jakarta: Court-Ordered Air Quality Monitoring Both dense networks whose readings trigger nothing automatically - Jakarta got its from a court, Accra from a donor.
• 🇰🇪 Nairobi: The Matatu Cash Light Fare Mandate Both digitised informal minibus networks without touching how drivers get paid — Accra mapped routes, Nairobi tried cards.
• 🇲🇽 Guadalajara: Jalisco Transit Routes Published as GTFS This mapped an informal network into GTFS to make it legible at all; Jalisco published a formal one already under contract.
• 🇲🇦 Casablanca: Casabusway Bus Rapid Transit (BW1 & BW2) Casablanca's 2024 busway got the signal priority and integrated ticketing Accra was scoped for and never received.
• 🇺🇸 Atlanta: MARTA Rapid A-Line (BeltLine BRT) Both BRT lines opened diminished — Accra's dedicated lanes were dropped, Atlanta's stations opened as temporary stops.
• 🇨🇮 Abidjan: Abidjan District Street Addressing (PADA) The neighbouring inversion: Abidjan numbered its buildings by the metre, but kept the address database for institutions.
• 🇨🇴 Medellín: SIMM Intelligent Mobility System & Traffic Control Center Both control rooms raise the same question - what the centre actually does. Medellin's staff retime signals by hand.
• 🇳🇵 Kathmandu: Kathmandu Metropolitan Air Quality Monitoring Dashboard Nearest peer by size and youth: Kathmandu's nodes are city-run, Accra's are university-run on grant money.
• 🇺🇸 Houston: Houston's Enhanced Air Quality Monitoring Network Both networks run on outside money rather than a city budget line — Accra's on a Clean Air Fund grant, not municipal funds.
• 🇨🇴 Medellín: Prepaid Smart Water Metering (Agua Prepago) Prepaid utility metering with the same tension between access and disconnection - water in Medellin, electricity in Accra.
• 🇨🇦 Toronto: Toronto Hydro Smart Meters and Ontario's Time-of-Use Pricing Mandated meter rollouts whose benefit case their own auditors and regulators questioned afterwards.
• 🇿🇼 Harare: Prepaid Smart Water Meter Rollout Neighbouring prepaid-utility disputes: Accra's regulator and utility clash over drain rates; Harare's scheme faces a High Court challenge.
• 🇹🇿 Dar es Salaam: Ramani Huria Community Flood Mapping Same funder, method and years; Dar mapped about half a city's wards, Accra four neighbourhoods on one river.
• 🇸🇳 Dakar: Dakar Bus Rapid Transit (electric BRT) Dakar built segregated lanes first and then bought buses; Accra bought buses and fare cards, then cancelled the lanes.
• 🇱🇷 Monrovia: LRA Digital Mobile Tax Gateway Two West African authorities collecting public money over USSD on any phone, no smartphone or internet needed.
• 🇨🇩 Kinshasa: DGRK Digital Tax Collection Platform Kinshasa built a web portal for property tax; Accra built billing plus a short code, and hired a contractor on commission to work it.
• 🇹🇳 Tunis: Recette Virtuelle: Tunis's Online Property-Tax Office Accra centralised property-rate billing nationally and then pulled back; Tunis kept its own municipal channel for seventeen years instead.
