The hour glass traffic light and the folding shoe seem to be the most useful...

Traffic lights with time-indicators already exist, but they look less cool. I've seen two variants, one with a ring of white LEDs that light up one by one, and one with a digital LED clock that counts down the number of seconds until the light changes.

I've seen some in China rather similar to the one in the pic. They have a light like a vertical bar graph that reduces in height as the change time approaches.

Hour glass traffic light is the best thing I've seen all week!

Not hourglasses, but in Hungariaorszag they've had countdowns on traffic lights for quite some time. The first ones I can think of where in Veszprém and have been their maybe 6 or 7 years.

isn't there the danger that drivers race to squeeze through before they change red, though?

How exactly would that be different than from today? 
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

I think it's the difference between 'you have an unknown amount of time' and 'you have this amount of time' to get through the light.
when the amount is unknown (and variable) I would think it more likely that drivers would err on the side of caution and slow down.
perhaps 'm wrong, but I feel that given a countdown to Red, people may think they have time and 'go for it'
(By 'people' I mean all the otehr drivers, obviously, not me - I am the perfect driver!)

Agreed.
Around Chicago (and probably many cities) they have countdown timers on some of the pedestrian walk / don't walk signals. Invariably approaching pedestrians start to trot (or run) when it gets close and end up causing more problems than not.

I believe the answer is to combine countdown traffic lights with severe sentencing for going through a red light. i.e. no fines, but jail terms, or death by suffocation.
With a countdown timer there'd be no excuse.

In my experience, pedestrians treat traffic lights as a useful tool to 0) press a button to stop cars, and 1) get an indication that it's definitely safe. Red just means "look both ways before crossing".

It just makes sense.
There are only 10 types of people in the world, those who understand binary and those who don't.

Indeed! Some cool stuff, some stuff that exists.
But yeah the traffic lights are the best 
if(this.signature != "")
{
MessageBox.Show("This is my signature: " + Environment.NewLine + signature);
}
else
{
MessageBox.Show("404-Signature not found");
}

While everyone are impressed with hourglass traffic light it is the worst idea listed. I mean good luck with all those color blind drivers and pedestrian.
|
|
|
|
|
Perhaps we should make it illegal to be color blind?

Well you got that Point!
But what about a Traffic light hourglass that consists of green yellow and red. Every part is its "own" as green pours into yellow into red? 
edit: them typos!
if(this.signature != "")
{
MessageBox.Show("This is my signature: " + Environment.NewLine + signature);
}
else
{
MessageBox.Show("404-Signature not found");

I like the Nightlight with Portable Glowing Orbs, seems like it might be useful for an old codger like me at night.
As I grow older I've found that pleasing everyone is impossible but pissing everyone off is a piece of cake.

Rubbish! Use the bloody light switch and them young buggers can wake up!

Excellent for use in a sietch.
You'll never get very far if all you do is follow instructions.

Well in India, now a days there are count down timers for Red. People switch off their motor-bikes, scooters, cars on Red and can start just in time before it is green again. Saves fuel (probably)  , reduces pollution. So I like it.
|
|

|

So, these engines use less during starting then during running on a low speed?
Only reduces pollution if it saves fuel, which again, was unsure. I'd recommend leaving the vehicle running, without turning up the gas.

I saw once in China timer traffic lights... they are really useful and work really well in ultra-crowded places as people are ready to press the pedal as soon as the light goes green!
