I have a long commute. Since I don't spend my time
texting, reading the paper, or talking on a cell phone like
the other drivers, I tend to notice subtle differences in the
way various lights are timed and controlled. I hit a
disproportionate number of them as they're turning yellow.
and found that some assume the pack of
cars are doing the speed limit, and some assume the driver
is going 10 over. It took me years to log enough anecdotes
mentally to figure this out. Surely there has to be a better
way. Proposed is an in-dash messaging system to let you
know how fast to drive to hit the next light green. It would
combine GPS and municipal computer systems. It would
serve as a bridge technology to eventually automating
bidding for greens
An old idea, with some of the same motivation as this idea [hippo, Oct 01 2012]
||Didn't we do this before? There would be a system that shows a display on your dashboard to speed up or slow down in order to make the next light. I think a couple variations of that have been posted.
||It's something that definitely should exist because we would probably save millions of barrels of oil if intersections flowed more smoothly. If all of the traffic lights were computerized they could be coordinated to communicate with cars. Imagine how easy it would be to drive if you could coast through green lights at most of the intersections you came to.
||It's a nifty idea, to be sure, but in some regions sensor-
controlled signals are making the notion obsolete.
||// Over time people would learn to follow the strange
behaving cars. //
||I already do, but not because I'm trying to make the light.
I'd just rather stay behind a drunk driver than try to pass
||It would take a while for the police to catch on. Erratic
driving, even within the law, draws traffic cops like ravens
to roadkill. Not that I'm trying to directly contradict you,
but I feel this is a parallel discussion to that taking place
across the hall in Car Navigation For Humans; more people
relying on an electronic device to tell them how to drive
does not seem likely to improve traffic conditions, at the
very least not at first.
||// ILS type approach cones //
||That brought to mind some amusing images; rush-hour
traffic directed into holding patterns while drivers rely
solely on dashboard information to navigate, never even
glancing out of the window for visual verification.
||...and "bidding for greens" (link) solves the problem by allowing you to accelerate towards the next traffic light and 'buy' a green light timed for when you arrive there.
