Why does driving isochrone ignore some rural roads?

I just placed a 50km driving isochrone around Yamoussoukro for an analysis we are doing at the moment - looking at the results I am a bit confused why some rural roads in the surrounding area are ignored? See screenshot.

To compare the results I also calculated a 50km hiking, and a 50km mountain biking isochrone around the same point, but the results did not differ significantly and many rural roads continued to be ignored.

Can you provide any insight as to why that is? Thank you!

Hi @najusten,

could you please provide the exact request (either url link from web application or API request body) as well as some specific examples of rural roads you would expect to be included in the isochrone?

Regarding the screenshot, i’m not sure what i’m looking at here?

Best regards
