Issues arising due to irregular (& many times non-existent) road naming

In OpenStreetMaps, as in real life, many roads, especially smaller, residential roads tend to not have names. In the OSM database, due to lack of: a. Official names b. Data sparsity radroads.py is having some issues working.

I tried to work through the code, as the function was not working. I am guessing there may be some changes to the original OSMNx package, because of which these errors might be happening.

Due to a lack of street names, there are errors in determining the street lengths, and they are instead measuring street segment lengths, as illustrated here in Chandigarh: image

However, when looking at a city like Mumbai, where there is a higher likelihood of user-generated content, and street names uploaded to OSM, we see the longest street is highlighted as the Eastern Expressway: image
