Bengaluru

Every editorial link from Bengaluru'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.

• 🇩🇰 Copenhagen: Copenhagen's Cloudburst Management Plan Copenhagen answered its 2011 cloudburst by rebuilding drainage; Bengaluru measures rain in drains that hold about 80 mm.
• 🇰🇪 Nairobi: Digital Matatus Open Mapping Framework Nairobi mapped its informal minibuses into open data in 2014; Bengaluru's drivers' union app books its rickshaws without taking a cut.
• 🇫🇮 Helsinki: Whim — Mobility-as-a-Service App Whim charged riders one monthly fee and went bankrupt in 2024; Namma Yatri charges drivers a flat fee and takes nothing from the fare.
• 🇦🇺 Melbourne: Urban Forest Visual & Email-a-Tree Melbourne's tree map drew love letters it never asked for; Bengaluru recruited 124 lake volunteers and watched the logins fade.
• 🇳🇱 Amsterdam: Signalen: Open-Source Public-Space Reporting Platform Amsterdam auto-routes residents' reports with an open classifier; Bengaluru routes lake complaints too, plus contractors' daily photos.
• 🇦🇺 Sydney: SCATS — Sydney Coordinated Adaptive Traffic System SCATS has retimed Sydney's signals from a control room since 1975; Bengaluru's police started swapping fixed timers for cameras in 2024.
• 🇭🇰 Hong Kong: Water Intelligent Network (WIN) Leak Monitoring Hong Kong's WIN scales the acoustic leak-detection BWSSB is piloting: 2,400 metering zones cut citywide leakage to 13.4%.
• 🇨🇳 Shanghai: Flood & Typhoon Command System Shanghai pools gauges, pumps and 14,000 estates' reports on one map; Bengaluru routes 105 drain sensors to its command centre.
• 🇩🇪 Berlin: BLUME Air-Quality Monitoring Network Berlin runs about 15 reference stations and publishes the data openly; Bengaluru has about 14 for 14 million people.
• 🇬🇧 London: Breathe London Air-Quality Sensor Network Breathe London put 400+ low-cost nodes across every borough; CSTEP runs 40-55 on a 1 km grid and calibrates them against reference kit.
• 🇫🇷 Paris: Seine Bathing-Water Sensing & Public Swimming Return Paris tests the Seine daily for bacteria; Bengaluru's lake pages track sweeping and de-weeding, not water quality.
• 🇫🇮 Helsinki: HSL Open Transit Data & the Digitransit Platform Helsinki opened its journey-planner API in 2009-10 and grew a platform others reuse; Bengaluru's first open feed came in 2024.
• 🇺🇸 San Francisco: NextMuni: Real-Time Muni Predictions & the Fight Over Who Owned Them San Francisco's predictions reached apps in 2009 only after a licensee had one pulled from the App Store — the same fight over reuse.
• 🇬🇧 London: London Adaptive Traffic Signals (FUSION / Real Time Optimiser) London projects up to 14% less delay from FUSION across 6,400 signals; Bengaluru's police claim 25% on corridors as citywide speeds fell.
• 🇵🇪 Lima: SEDAPAL Smart Water Meters — Remote Shutoff Pilot Lima's utility can shut a valve remotely from 43 pilot meters; Bengaluru's promised smart meters are still a 2,000-connection pilot.
• 🇮🇩 Jakarta: Jakarta's Subsidence Monitoring & Groundwater-Free Zones Jakarta regulates the source rather than the tap: nine zones where large buildings may not pump groundwater, on metered reporting.
• 🇨🇳 Shanghai: Shanghai Metro's Driverless GoA4 Lines Shanghai runs five GoA4 lines; Bengaluru's signalling is rated for the same, but its Chinese-built coaches arrived years late.
• 🇧🇩 Dhaka: Dhaka WASA District Metered Areas and SCADA Bengaluru hunts leaks with robots inside the pipe; Dhaka cuts the network into metered zones and reads the difference at the boundary.
• 🇬🇧 Maidstone: Drone Fly-Tipping Detection & Enforcement Maidstone flies drones to catch fly-tippers; Bengaluru flew them over rooftops and flagged 688 crore rupees of under-declared tax.
• 🇹🇿 Dar es Salaam: Ramani Huria Community Flood Mapping Two ways to map a city: students mapped Dar es Salaam's flood-prone wards openly, Bengaluru's corporation mapped who owes what.
• 🇨🇩 Kinshasa: DGRK Digital Tax Collection Platform Kinshasa moved tax filing to a website; Bengaluru put the tax roll on a map — and only door-to-door surveys later widened the net.
• 🇷🇸 Belgrade: Belgrade Sitraffic Adaptive Traffic Control Belgrade reports 26% faster mornings from adaptive signals, Bengaluru up to 25% — both operator figures, neither independently checked.
• 🇮🇳 Chennai: Integrated Dynamic Flood Early Warning Platform Chennai forecasts ward-level flooding days ahead; Bengaluru's gauges and drain sensors mostly tell crews where the water already is.
• 🇮🇳 Mumbai: Mandatory Air Quality Sensors at Mumbai Construction Sites Mumbai forces builders to measure their own dust and struggles with compliance; Bengaluru's gap-filling sensors are run by a think tank.
• 🇮🇳 Mumbai: Mumbai One Integrated Ticketing App Two answers to fragmented mobility: Mumbai's authority built one ticket for 11 operators in 2025, Bengaluru's drivers built their own app.
• 🇮🇳 New Delhi: Open Transit Data Portal & Live Bus Feeds Delhi opened bus GTFS in 2018 and still has GPS units dropping offline; Bengaluru followed in 2024 with buses missing from the feed.
• 🇮🇳 Mumbai: Mumbai Water Distribution Improvement Programme Mumbai went after leaks to find water and stalled at 18.6% of the work; Bengaluru went after demand — bans, fines and reuse rules.
• 🇮🇳 New Delhi: Delhi Metro's Driverless Lines: Magenta & Pink Delhi kept operators aboard its 'driverless' lines until 2024-25; Bengaluru's unattended-rated line likewise opened with a driver.
• 🇮🇳 Mumbai: Mumbai Metro Aqua Line (Line 3) — Automated Underground Corridor Mumbai's Aqua Line also opened driver-operated on unattended-capable CBTC in 2024 — it waited on clearance, Bengaluru on trains.
• 🇮🇳 Mumbai: Mumbai Water Distribution Improvement Programme Mumbai tried the big-contract route to the same goal in 2014; it collapsed at 18.6% of the work, where Bengaluru starts with a pilot.
