Your Car Will Tell You How To Hit the Next Green Light

cartechboy (2660665) writes "Hitting that red light sucks. We've all been there, and you know what I'm talking about. But what if your car could tell you the ideal speed to maintain to hit the next green light? That's exactly what's going to happen in the near future thanks to car-to-car technology. Many automakers are already working on this new tech, and Honda's the latest to trial such systems. This is all part of what's known as Universal Traffic Management System which will eventually provide feedback on car-to-car and infrastructure systems before they go into practical use. The system will also be able to tell the driver if a red light is likely to show before reaching an intersection so the driver can slow down, or notify the driver when that red light will turn green. All of this may seem like something that's supposed to benefit the driver's temper, but in reality it's to help save fuel and lower emissions without any physical changes to the car. This is the future, and your vehicle will talk to other vehicles whether you like it or not."

Green wave system

[Knightman]

In some parts of the world they have dynamic speed signs that tells what speed you need to drive to hit each traffic light when they are green, aka. a green wave. Works like a charm no matter what kind of vehicle you are driving.

True story: The lecturer that taught us general relativity at university was a fantastic guy that was also pretty good at drawing cartoons. For one of the questions on the final exam, he drew a scene of a guy being stopped by a policeman: "I am stopping you for crossing the red light." "I saw it as green, I swear officer." "Fine, then I will write you a ticket for speeding." The question was to calculate the speed of the car, given the wavelengths of green and red light and the velocity of light.
