4/🧵
Here's the key thing: Once you start monitoring traffic in cities 24/7 using data that's *already available* from our cars + mobile devices (and yes, it's anonymized) you can actually chop down the cost of maintaining existing traffic signals.
No more expensive traffic studies to re-time lights. Crews can be redeployed to adjust timing on existing signals. "Green waves" of lights can be orchestrated to speed traffic from one signal to another when needed.
