The main idea seems to be that when the arrows are green, you can drive without having to worry about other traffic intersecting your route. When it is just the green light, you still have to yield to traffic coming from the other direction when turning.

Most European tram signals are not done with arrows, but with completely different symbols. I've posted an example of those 4 years ago in this topic: http://www.skyscrapercity.com/showpo...&postcount=142

Either way, it's an extremely weird set-up:

I mean what is it trying to say???:


So there is a green arrow to go straight BUT at the same time, there's also a red light.

What is it? Stop? Go straight? The traffic light is defective?

Btw, I noticed that the bottom row traffic lights are directional arrows while the top row lights have solid light circle lights.

The problem is: If they both light at the same time, then to whom is addressed for? To whom is it directed?

Overall, why the confusing set-up?

P.S.
Maybe someone from Japan can answer or explain this.......

Looking at the Chicago pedestrian traffic light with the seconds counter I thought about the fact that in Bulgaria at many intersections the traffic lights for cars also have such counters, which I think are not common in any other european country? Maybe it has been discussed before in this thread, I haven't read all the pages...









Another similarity I found only with american traffic lights is having traffic lights hanging not on metal poles, but on ropes, like this:

sorry for the crash pictures, but they are of the few I found googling for these traffic lights

You can also find traffic lights with counters in Romania. For example in Arad there is no counter at any traffic light, but in Timisoara there are counters at almost all traffic lights.

Traffic signals with counters are archaic with a static cycle. Traffic signals should be network or traffic-dependent, not time-dependent.

I agree, but still, it's a good thing to know how many seconds of red/green light you have left.

Goldenox has explained it, although I think it is little bit different. so, my opinion is that red light with green arrows allows driving in "green" directions, but with yielding the traffic from other directions.
"whole" green light means free passing in all directions without yielding. at least that would be the most similar to European and American rules. correct me if I'm wrong.

Japan doesn't use fully separate signal heads for different directions of traffic like you find throughout Europe and the Americas. You only get the standard red/amber/green head with supplimentary green arrows where necessary. If a green arrow comes on, that overides the red. This signal suggests that whilst traffic going straight and left can go, right turning traffic must wait.

But there are also situations when red is turned on and all three green arrows too (left, right, straight). What about that?

That means that you can go in all directions but oncoming traffic has a red light. Weird, I know.

I would think that the three aspects/lightspots on the top is a type representative of the oncoming traffic signal aswell as a signal for the traffic seeing it. (Don't know, but would thought so)

This year I've been in Malta and I saw such traffic lights:

I was travelling with the bus and while we were 100 m from the intersection, traffic lights were full green and the right arrow was off (2a). Bus driver stopped at the moment, and only when green arrow was on (2b), he turn to the right. Does it mean that full green doesn't allow to turn right when the arrow is off?

Next time I saw such traffic lights:

[IMG]http://www.************/forumas/picture.php?albumid=510&pictureid=32864[/IMG]

The question (especially for Maltese people) is - does it mean that green doesn't allow to turn right when the right arrow is off? When it is true, then it is simillar to our old system traffic lights, when turning traffic has no red light:

Maybe the bus driver misunderstood the signal. We have a similar system in Norway only with a yellow aspect aswell as the green arrow you are refering to, and there you can make the turn even though you don't have the protected arrow. The only thing is that the turn is not protected, and means you have too yield to oncomming traffic and pedestrians in the pedestrian cross. (maybe you already know this!)

Where I live now, there is a traffic light cross with this kinds of aspects, but I've seen many times people standing still just waiting for the green arrow, even though it is clear to make the turn.

We have few of these in Sofia. As there are no arrows on the full green, it means it allows all directions, including the right one.

I'm not Maltese but being from the UK, I think, is the next best thing, as I believe Matlese traffic lights are pretty much based on UK sequencing. The full green means turning is allowed but that right turners must yield to oncoming traffic. The green arrow poining right means that oncoming traffic have red. I'm guessing that your bus driver was either waiting for oncoming traffic or his viewpoint was that he could not see clearly whether it was safe to make the turn and so waited for the arrow to appear.

The point is that some drivers from ex-Sovjet countries don't know that they may turn on full green with arrow off in West countries. Our traffic rules don't allow this.

According to dsanto on the previous page, that rule is getting phased out in Lithuania. New signals installed since May 2012 are now supposed to be set up like what you find in most of the rest of Europe, although flashing green is still allowed apparently.

The rule is still valid because of old traffic lights. Just this rule is not actual for new traffic lights that are installed after 1st May because new traffic lights have three arrows for turning traffic.
