What is the advantage over motion/heat detection that has been in use at traffic lights for over a decade? If the new tech just uses the smartphone connection to detect if a car is approaching, why not simply detect cars? That also allows to control for size of the car, queues and isn't dependent on the smartphone used.

The article mentions the smartphone or eventually autonomous cars will be able to time their speed to alleviate the "wait times" at the light. Its not just detection but immediate action thereafter to the vehicle, not just the lights themselves.

It is about big brother having more data to digest.

It seems like a necessary thing to do, rather than relying on car's CV algorithms to (1) detect traffic lights and then (2) identify red/yellow/green. But, it poses an easy vector for a malicious actor to cause chaos. I hope this system will be built as an universal open standard that can be tested for such vulnerabilities.

I can only think of the movie Italian Job, where the napster guy hacks into the traffic lights and get a free pass for their minis.
