This info wasn't enough for me to figure out the location, but it's something. If I was serious about the challenge or there was way to monetize this, I could write OpenStreetMaps / Google Street View scraper that would figure out the location in a matter of minutes.
And as a South African, I would immediately know it was SA just by the look of the traffic lights and street signs.
I agree that there is no way to know which city it is in the first photo.
In the article there is the line: "Some quick Googling revealed several universities in Pretoria, and I decided to wing it and take a closer look at the Pretoria skyline."
That's glossing over a very important part of figuring it out. Because once you know which city it makes it much easier.
If you look closely, you can see stenciled markings on the yellow poles. These felt like official markings to me so I tried to figure out how to use the markings to narrow down the list of candidate cities.
According to Wikipedia, the _Burger_ newspaper is distributed only in three regions: Western, Eastern, and Northern Cape. There are not too many large-ish towns in these district.
So I made a list of all towns with >50k inhabitants. Looking at those cities on Street View one by one, I found there are only two towns where the yellow poles have the exact same typeface of stencil numbers on them: East London and Uitenhage.
So I took a closer look at either town. (After a few misses, you quickly get a feeling where to find the parts of towns where the roads actually have traffic lights). With a bit of luck, I actually managed to locate the first picture just by randomly clicking on corners. Its coordinates are 33.7648S/25.4012E.
Identifying its SA is extremely easy with the Dutch text and newspaper names. There is no real hint this is Pretoria and not somewhere else. The satellite photos don’t have enough resolution to help find the stop lights (which appear not too common looking at street view).
You can kind of see a double roof in the building in the background, and the road arrangement, but it would take days to manually look at every city intersection.
I guess the easiest approach is to post the image on a forum / twitter and get locals to chime in :)
