Well, let's say that there is an alternative way to advise people the traffic lamp is going to be green by showing another yellow light between red and green, instead just between green and red.

Unfortunately it's not used in Italy, but it's wide spread in Switzerland.
IMHO it's way more useful, than watching the countdown, for example 1 minute before starting.

They've been installing these at quite a few major intersections in Shanghai.

I've only seen countdowns for pedestrians, not for vehicles. (And the timer will appear in conjunction with a green light or walk signal, rather than with a red/don't walk. To show you how much time you have to get across.) They appeared in Washington maybe ten years ago and have shown up in Philadelphia more recently. When I first encountered them in Washington they used to make me nervous. But you get used to them, and they do serve a useful purpose....

They are a bit useless... They just encourage people to be more competative at traffic junctions against eachother on 2-track lanes.

I find the ones for pedestrians are useful: they let you know how fast you have to walk before the drivers waiting for you to cross their path start getting ornery.

I've only ever seen these counters on the internet, never seen them in real life.

Toronto and Mississauga in Canada have these countdown stop lights for pedestrian crossings.. though not for all the pedestrian crossing lights.

Mumbai in India has these countdown stop lights for vehicles at one major interesection for sure.

They're also useful for drivers (especially when the pedestrian ones coincide with the regular ones most of the time, like it is in Toronto). I don't think they cause "competition". If I'm approaching an intersection from relatively far away and I see that there are 1-2 seconds remaining, I start slowing down. I know that in this situation, if I don't slow down, I will either have to run a yellow light (likely a deep yellow) or hit on the brakes much harder to stop.

Of course, as I mentioned before, sometimes at night the counter resets itself if there is no conflicting traffic or pedestrians, but in general it's not a problem.

Agreed! There are many of those "countdown" intersections in Chicago and I find them incredibly useful, especially at intersections where they have installed those red light cameras. Less of a chance you'll run the red and have a night $100 ticket waiting for you in the mail.

Still, I would just consider them a luxury, Any good self-aware driver or pedestrian should not need to rely on fancy countdown timers.

Of course but they certainly don't hurt.

A Serbian Industrial Designer invented a new form of the count-down traffic light:

In Belgrade they have for at least 20 years or longer. They are put for a ecological purposes. Mostly they are on intersections where are long waiting times.

They are also present in other towns in Serbia such as Kragujevac:



There are also lot of them on pedestrian crossings

installation




and finally new Serbian product

The UK doesn't have them, bar one experimental pedestrian crossing in Glasgow. I don't see the point, to be honest, plus virtually all of our signals are vehicle/pedestrian-acuated.

The US recently added requirements that all new pedestrian crosswalks have timers unless the time is set for less than 7 seconds. Traffic lights for vehicles do not have countdown indicators.

Dublin has countdown timers on some crossings for pedestrians. They countdown to green though, not red (opposite to Canada & I think the US), to try and discourage jay-walking. It doesn't always work though, you still see some people crossing with 5 seconds left til the green man. Of course if they really wanted people to stop jay-walking they could just make timings much more pedestrian friendly.

I've never seen them for cars here though. We also don't have the red+amber sequence so it can be a bit of guesswork when unfamiliar lights are going to change. Not so great for the environment then.

Not so sure about the other Irish cities but I assume they have them too.
