00 The problem
When the car across from you is also turning left, it hides the oncoming lane. So you guess.
01 How it works
The camera sees
what you can’t.
01Blind zone
The opposing car hides the lane behind it. You can’t see anything in the shaded area.
02Camera
The traffic camera above the intersection sees over it. It’s already installed.
03Estimate
A small computer on site tracks oncoming vehicles and estimates when each one reaches your path.
04Signal
One extra light beside the signal shows Wait until the gap is long enough, then Clear.
02 The signal
Clear, or wait.
One light beside the existing signal. It answers a single question: is the gap long enough to turn?
Wait
An oncoming vehicle is due too soon.
- In the car
