Top FB Comments | Can't be used because the shape is the same for all three lights. The colorblind would not be able to distinguish between a red and green light. | Great idea if you want to encourage drag racing. | Not a good idea. Red/green colorblind would not be able to differentiate stop and go. At least with the three light system, you know the order. | Absolute color blindness is very, very rare. It's usually a case of someone not being able to differentiate between colors (say, green and blue).
Now the real issue here is that traffic lights are not usually set on a static timer, they vary depending on conditions at the intersection and their timing can, and does, change within a period of only a few seconds as cars come to and pass through the intersection. Imagine having to watch that red hourglass stall, or slowly refill while sitting at a light. Yuck.
Nifty concept, but if isn't broke, don't fix it. | To all you people who say it'll encourage drag racing: anyone with half a brain can count down when the green light is coming on traffic lights the way they are, so nothing will change. This is a brilliant idea. | This is so not compliant with any Manual of Uniform Traffic Control Devices. This is not a sensible design. It is flawed and would not work as intended. People would abuse it and the color blind would be confused. | Overthinking it, the 3 light system is simpler and more straight forward | Impossible. People will run more lights because they will attempt to 'time the lights' even worse than now, causing an increase in speeding leading to even more accidents causing even more slowdowns. So in the long run, a stoplight showing how much time is left will only make things slower. | great for drag racer, waiting for countdown while broommm brooomm revving up engine | Interesting, except it wouldn't be good for the color-blind. The beauty of traffic signals as currently designed is the lights aren't just color-based, they're also position-based. A light at the top of a stack of signals always means stop. We don't need anything else to confuse our pool of already undereducated motorists! | Just more $$$$$ wasted.....why change what works already. Government isn't $ broke $ they are having so much fun with our money!| the "advantages" is not enough incentive to change all the traffic lights. if it had something like "less power consumption", "more durable", or "cheaper to make", maybe. | Other than the issue with colour blind people who use the location of the three lights to know which is which; it's not intuitive to use an hourglass at all. Since traffic lights use road pressure signatures to know when someone is waiting on a less busy street versus the busy street that has the green. How could you have a "wait timer" when the computer itself doesn't even know when it will change? This is trying to fix a problem that doesn't even exist. | Engineers would say, it would cause more crashes even with ticket cameras in place.| An engineer has to think of all users of his/her product, including the daltonist. This is just not good concept of traffic light.| Same problem can occure in a very sunny day, but you can avoid it using "Wait, Ready, Go" description below hourglass. Americans have description on signs everywhere. It is ofcourse just a good-looking gadget and you can use just timer beside conventional lights. It has been tested in my city for some time ago and it was very helpfull.| It wont work here in Africa, the people are already struggling to understand the conventional traffick lights | Bad idea people shouldnot know the timing it causes a lot of trouble we have the same system in my home town and it makes a real mess | What about all the lights that sense if there is a car rather then using a timer to switch? | That would kill the need to have a yellow light because the hour glass running out is telling you the light is about to turn red. | Allowing drivers to be more aware will prevent the waste of fuel. One of these can be added to each set of lights for drivers who are not color blind. The traditional lights can stay as well so that the color blind know what the signal means. | Let the bogans know how long to the green light so they can rev up and do some burnouts? Brilliant! | In India we follow the timer system.. I loved this concept a lot... It looks great.. | People with red green color blindness can't distinguish "Go" and "Wait" of this design. They know the order of light so they are walking safely now. | Problem with the yellow light is also that it is used in combination with read to signal "ready to go" and without red to signal "ready to stop". Or perhaps that's just where I'm from?
If you don't have that - it would be a great place to start. | It's a really cool idea but all we need is new traffic lights to distract and confuse the crazy idiots already on the road | Got in theory but in reality if you give people a count down they will go on 3 and not wait for 1. | Oh, is this so people will know how long they have to bee, impatient little, you know whats! Sitting at the light that they didn't stop at correctly, inching their way forward, stop and go, stop and go. | Traffic lights are red amber and green anyway so whys everyone moaning about colourblind people, is you can't differentiate between those colours then I don't think you can drive anyway, it's a good idea just a shame about the poor use of English and grammar in the briefing | Stupid and useless. Old stile is more comfortable, specially when the countdown is applied. | Can force people to drive fast while green hourglass lighting. | Colour blind people have driving licences what a stupid thing to say Horst Toberer you can still see which light is on just not the colours as otherwise that would mean you are fully blind! | It doesn't tell how long you have to wait, not as useful as a real countdown. | They already have lights that count down in certain countries. Vietnam have them and they are brilliant, although you do tend to speed up when you can see the green is near the end! | cant do it... a 3 seconds countdown before the green light? i would be racing all the time... and i wouldnt be the only one... | I think it's a really great idea. The technology we have it could from reading the amount of traffic every day at different times to speed up or slow down the timers.
And I'm into drag racing and drag racers will always find a way to race. You will never stop that. Unless of course you remove all testosterone in the world!!!lol | This is a terrible idea. Europe had a similar system that told drivers that the list was about to change green also, but this caused more accidents than anything. Drivers of the green light tried to beat the light and take off and the cross traffic stepped on their gas to gun through the intersection . They finally changed to the US system. | wouldn't change anything, and there's no way my eyes would be able to differentiate between a full/half full hourglass.
neat idea tho
