When traffic lights talk: a one-minute Short
When traffic lights talk
Short · about a minute
tap to start →What if traffic lights could talk?
They can. It's called V2X.
Cars that talk to everything
Vehicle-to-infrastructure, vehicle-to-vehicle and vehicle-to-pedestrian: short wireless messages about what is coming.
"This light turns red in 5 seconds"
Smart intersections share signal timing and spot hidden pedestrians, so cars get warnings earlier.
Quick guess
The connection drops. Can the AV still drive safely?
Not just for AVs
The same upgrades give buses signal priority, cyclists safer crossings and planners better data.
Remember this
AVs are self-sufficient. Connected streets make everyone smoother and safer.
