Safe breaking distances: tough to remember but vital that
you do. For set road speeds, they indicate the space you
need between you and the car in front to make sure that
you
can stop in time.
Street lights are... ah come now, you don't need me to
explain.
So, combine these two ideas
dear reader, making it easier
for drivers to recognise the distance they need to leave
and,
of course, light the road correctly.
These street lights are spaced in such a way to ensure that
a
2 light space is *always* the safe breaking distance for the
designated speed limit for that road: closer spaced on
residential road, longer spaced on motorways/freeways.
Drivers always know that they need to leave 2 lights space.

When I read the title I immediately thought the light would be built into the front of the vehicle, and tilt-up the faster you're travelling... but I like the idea of building a road to suit its conditions... It'll stop idiot road designers and building roads capable of 70 MPH, and labeling them 40 MPH (like the start of the A20) |
|
| |
Excellent idea, and lovely to see you back here. |
|
| |
Needs a better title, but I see the value in this. I, myself, always practice and test myself to use a safe following distance by approximating two seconds before my car reaches a shadow or other marking that the car in front of me just passed. It's cheaper to do, but I realize money is no object at the halfbakery. |
|
| |
And you don't need to remember the safe braking distances in feets, or convert feets to meters. [+] |
|
| |
Are the lights set on rails so they can move further apart
when it's raining? |
|
| |
2 seconds dry, 4 seconds wet... unless they changed
the world while I was out. |
|
| |
Double the number of lights space you leave in the wet... |
|
| |
// You'd have to constantly be moving these
lights around, meaning your idea needs a
way to address that. // |

I can't say this has ever really been a problem for me.
I always use a time-based limit; a method exactly like
that of XSarenkaX, although with a following time of
three seconds. |
|
| |
This, however, is a brilliant idea, although flocking
capabilities will be required for different conditions.
Might I recommend placing light poles a series of holes
along the roadside, each containing coilguns that will
eject light poles on a trajectory such that they will
land in other holes with the appropriate spacing? |
|
| |
I guess I never realized other people had to put so much
thought into braking distance*. I remember something
about the spacing of telephone poles from when I was just
learning to drive, but since then I've always just used my
intuitive judgement about when to apply the brakes. |

Good idea but still leaves the driver the choice; a
system of sensor-operated adjustable speed bumps
which are raised and lowered according to the speed
of the approaching motorist would remind them by
variable levels of road rumble that they're over the
sensible limit. |

What we really need is a sheep proximity sensor. |
|
| |
Ka mate, ka mate! ka ora! ka ora! |
|
| |
Sheep don't arouse me is all. |
|
| |
So, only 8". Is that arousal, or just happiness I'm
home? |
|
| |
Isn't the problem already solved with less expense
with those painted chevrons you get on the road?
Just need to paint them everywhere... |
|
| |
Paint the odd one blue to make motorways look like
a Wipeout track. |

In Chicago, they drive with the theory that if you can't tell what color the driver's eyes are in front of you, then you're not close enough. |
