Skin iGO nextgen by pongo (DISCUSSION)

Sorry for my ignorance on the subject, but the math is not an opinion.....

The speed, and also the average speed, they are the result of the division of a section between a point A and a point B with the time taken to travel it.

The software knows the point A, there are the coordinates in the speedcam file, but does not know point B, there are no coordinates of point B in the speedcam file, and in any case, how do it give me the average speed even before getting to point B?
It can only give the instantaneous speed detected by the satellite......

In Italy we know the coordinates of points B in our txt files, and I created the category "average speed end", I know the beginning of the stretch, I know the end, and in that stretch I have to be careful with my speed........ but I should do the same with the skin of Pongo or Frontzosd ......

Point A is only trigger for start of calculation (Av. speed zone start)... Software knows only actual speed, "measured" from satellites... It takes, for example, actual speed every 1 second, and calculate average ... So simple... Sum of 10 speed values, devided with 10 is Average speed, right? No Point A, no Point B...

There is also a second way of calculation. Point A is again trigger ... Then software saves time. Afterwards, software knows in every point your Avg. Speed. For example, you have driven 10 minutes and you passed 10 km, so Avg. speed is ... ?

I don't know how Pongo calculate Avg. Speed in his UX, but Point B is really unimportant for calculation. It triggers only End of "measuring"!

My question is, what's the difference between these two Av. Speeds?!?

Point A is starting point (must be known), point B is actual position (at present moment), no matter where exit point will (or will not) be in future.
B = Exit point, will be at moment when you reach that point.
Rest is math.

"Driving Avg. Speed" is average in last short period, another is for complete section (from A to B).

I have already said that

What is "last short period"?!?

There is a point A, and after 5 km there is point B. You have passed point A from 500 meters, let's call it point A1, from A to A1 is "last short period", with this example I answer also to your post#650, if point A1 is close to point A, the average speed and the actual speed are the same.

I made a check and maybe I understood where is point B. It's virtual, and it's on the data.zip, in the speedcam.zip file and in some sys.

section_beep_distance=150
section_beep_spoken_type=speech
section_beep_speech="Average speed camera."

these three strings are only for the "Average speed camera" category, the number should be the seconds after which the stretch ends......

A safer answer can only be given by Arimi, Pongo & C.

I continue the
Cameras of medium speed
changed the warning logic
for the zone, two cameras should be created
first (the beginning of the zone) with the limiting limit limit. The
second (zone end) with a speed limit of 5 or 0 km / h
can be deleted by clicking on it

Thanks to pongo

@BIRBANTE If that's true (and I think it is not), what is "the rule" for point A1? Is it 10%? Half way? 5 minutes before? ... Then I would like to know, what is a purpose of this? Why I want to know, what was my Avg. Speed in past?
And of course, why is then called "Driving Avg. Speed"?

These are just my assumptions, I do not know for sure if it is so. We are talking about a software that does not see and does not hear, it only processes the data in its possession. How do it determine when the average speed check zone is finished? It has no file with the coordinates that informs it of this, so it has a command somewhere that determines this thing, or after a lot of time, or after a certain number of meters..... I think it already does enough if it calculate the average speeds between A and B

I'm not a computer engineer, I'm just a user who breaks the software to look inside, understanding it little......

To get certain answers or the NNG technicians should answer you, or by the various Arimi, Pongo & C. that handle iGO for a lifetime.....

You trust too much of technology, the technology is not infallible, you can not take everything that indicates to you for absolute truth, the maps may be wrong, the speedcam files too, we are talking about a software that does not cost millions of euros......
