L.A. synchronizes its stoplights

Ian Lovett, reporting for the New York Times:

Other cities have chased to keep up, adopting centralized control of at least some traffic signals. But Los Angeles has remained at the forefront, with a system that is not only more widespread, but also faster and more autonomous than most others.

Now, the magnetic sensors in the road at every intersection send real-time updates about the traffic flow through fiber-optic cables to a bunker beneath downtown Los Angeles, where Edward Yu runs the network. The computer system, which runs software the city itself developed, analyzes the data and automatically makes second-by-second adjustments, adapting to changing conditions and using a trove of past data to predict where traffic could snarl, all without human involvement.

No mention of whether they’re prepared to integrate autonomous vehicles into the system.
