The question is not whether a city has sensors. The question is whether the people running the city can act on what the sensors reveal. For the past decade, India’s Smart Cities Mission has promised to transform urban governance through technology. Integrated command and control centres. Real-time traffic monitoring. Sensor-based waste management. Digital citizen services. The vocabulary is impressive. The results, measured against the needs of the people living in those cities, are harder to find.
The Smart Cities Mission, launched in 2015, selected 100 cities and allocated ₹48,000 crore over five years—later extended. Each city was supposed to develop an area-based development plan and a pan-city technology initiative. The projects that got funded tell the story: surveillance cameras, LED streetlights, WiFi hotspots, mobile apps. The projects that didn’t: footpath repairs, drainage clearing, public toilet maintenance, tree planting.
The Integration Gap
The central idea of a smart city is integration. Sensors collect data. Data flows to a command centre. The command centre dispatches responses. The citizen benefits. In theory, this is elegant. In practice, Indian cities are not integrated. They are fragmented across multiple agencies with overlapping jurisdictions and competing incentives.
A sensor that detects a garbage pile in Bangalore cannot dispatch a municipal worker to clear it because the worker reports to a different department than the sensor’s control room. A traffic camera that detects congestion cannot adjust signal timings because the traffic police control the signals and the smart city corporation controls the cameras, and they do not share data. The technology is present. The governance that would make it useful is not.
This is not a technology problem. It is an institutional design problem dressed in technology clothing. The sensor reveals what anyone walking down the street already knows: the garbage is there. The question is whether anyone has the authority, the budget, and the incentive to remove it. The sensor does not create that authority. It only makes its absence more visible.
What a Smart City Should Actually Do
A smart city is not one with the most sensors. It is one where the systems that already exist actually work. A smart city has drains that carry water. Buses that arrive on schedule. Footpaths that are continuous. Public toilets that are clean and open. Streetlights that function after dark.
None of these require sensors. They require maintenance budgets, clear accountability, and political will. The tragedy of the Smart Cities Mission is not that it spent money on technology. It is that it spent money on technology instead of spending it on the unglamorous work of making existing infrastructure function.
If Indian cities want to be smart, they should start by fixing what is already broken. The sensors can wait.
