In my opinion, the anomaly concerns only category 2, (speedcam_category:2 - Built-in speed camera - Type 2), and not category 4, (speedcam_category:4 - Red light camera - Type 3).

In Italy the txt files with Type 2 correspond almost totally, (I have not checked them one by one), to the Traffic Light.
A judge's ruling ruled that in Italy, the traffic light devices cannot perform the double function, or detect speed, or traffic light infractions.
But I cannot generalize the Italian situation with the rest of the world, so I have "translated" category 2 in Red Light and Speedcam as category 11, but category 11 appears only with the "original" spc files.

I believe that we should not fossilize on the Eur+ sequence, if it is ascertained that the txt files with Type 2 correspond to the semaphores we will change the Type from 2 to 3, otherwise everyone will change it as they see fit.
I have never used the Eur+ sequence, until recently I used all Italian categories and now I use an Italian/French/Spanish sequence.
