For years, sparse and lagging telemetry left our transit network navigating on guesswork, forcing us to make massive assumptions about how trips were performing in real time. By shifting from sluggish, 30-second snapshot intervals to a massive, high-density 1-second continuous engine, we completely transformed our analytical visibility from blind speculation to flawless spatial precision. This presentation charts that high-tech journey, revealing how conquering a 35-billion-row data universe unlocked the ultimate blueprint for a responsive, modern network.
