Australia is trialling AI traffic lights. How will they change our roads?

Have you ever been stuck at a red light, wondering why you're still waiting when there's nothing coming the other way?

Australia's first trial of AI-powered traffic lights will test whether artificial intelligence can ease that frustration by responding to what's actually happening on our roads in real time.

A faster journey sounds appealing. But if we let AI decide who gets the green light, how do we make sure those decisions are fair and safe for everyone using the road?
