In my travel across the world i havent come across any global
standards for road naming.
Yu name them locally as per local requirements and traditions.
Same goes for expressways and highways and they mostly have alpha
numeric names, like the ones use in PK. So thats as far as the
standardisation goes.
I have been looking at some segments of N-5.
Be advised that Sothwards of lahore i.e from Lahore to KHI, N-5 is NOT
known as GT Road. it is wong to call that section GT Road.
Only the section of N-5 from Peshawar to Lahore is called G.T. Road.
This original GT road also continues to the Wahga border in Lahore
district, but as far as i know this section which extends to Wahga
border is NOT called N-5.
This essentially means that N-5 is strictly an internal highway for
pakistan extending from KHI to Peshawar.
So from Lahore to Peshawar the name should be
N-5; Official/Preffered
G.T. Road; Colloquial
Lastly, I have a recommendation for all mappers in PK.
Let us revamp N-5 all across Pakistan and draw it as a single road.
N-5 in many sections is drawn as split roads which I think is not
needed and a single merged road is what is recommended by Google Maps
standards. Split roads exist only if there is at least a 10 feet wide
physical divider between the two directions of the road. This divider
could be a green belt or say a canal or something.
No physical dividers as wide as 10 feet exist on the N-5 from what I
recall. So in that case and especially where such wider dividers are
not present, the road should be drawn as a single merged road. This
will help in maintaining the road here on GMM
And yes this requires significant rework but then at least all the
highways would bear a standard look!
