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."

Isn't this why they put those countdown timers on the crosswalks?

The problem is all the people behind you that will speed up and tailgate you so you can they can have the pleasure of sitting at a red light faster. Your car, in a 35 mph zone - tells you to go 20mph to avoid the red - the person behind you tailgates you and honks their horn.
Even in India there are count down clocks on many signals, telling you how many seconds of red is remaining or how many seconds of green is remaining. Just simple feedback like this would reduce accidents and save fuel for the drivers. This technology is easier to implement in a phased manner all over the country rather than fancy-nancy technology involving "the cloud" and such stuff.

Stop putting stop signs/lights every 50 feet. Build more roundabouts.
Why the hell do I have to stop at a stop sign at 3 in the morning with no one in site and waste gas. Make it a mini-roundabout. Teach people how to drive.
This article presumes people give a rat's ass about saving fuel or driving safely. As those of us who drive on a regular basis can attest, more and more people seem to be of the mindset that no matter what, they will accelerate as hard as possible just so they can slam on the brakes as hard as possible at every opportunity.
This morning I had a guy literally on my rear bumper (less than 1 meter) and when it looked like there might be an opportunity for him to jump into the lane next to get around around me, he tried to take it. Unfortunately for him he misjudged the line of cars in that lane and had to swerve back behind me.
He wasn't going to get anywhere faster as there was a red light for us (a left turn), and he would have only gotten one car ahead, but by golly he was going to use every drop of fuel he possibly could just to try and do it.
I, and others, can relate story after story about people like this, and the only thing this proposal will do is add costs to vehicles (and those driving them when the system breaks down), cause more people to try and beat the red light which means more accidents, as well as people slamming on their brakes when they misjudge the timing, also causing more accidents.
Once again, we are trying to find a technical solution to a human problem rather than fixing the human problem.

So correct me if I'm wrong, but if all drivers adopted this, wouldn't it result in traffic in a lane approaching a light from converging together into "clumps" or "waves"?
Cars near the front of any given clump would be slowing down in order to arrive at the light after it has stopped being red and become green. (Close) Behind those cars would cars which would have passed through during the green interval regardless of this system. At the back of a clump would be cars who are speeding up to attempt to "get in" on that same green signal.
Ultimately it would result in cars travelling very close together, with huge spaces between "convoys". It might even be more efficient, so sure - but while there are still humans behind the wheel, this seems dangerous as everyone will always be "tailgating". Once CPUs are behind all the wheels, it will be trivial to implement using the "Internet of Things".
Why is your desire to put your foot down, and your misapprehension that you'll save much journey time by doing so a hyper-miler's problem?
