I know there was a post regarding this question before / as well as an answer to it but I am still having a hard time on it. Can someone please explain?

Hi @ZSAKAAMINI,

Thanks for your question! I found the previous post and my clarification of the answer:

> [@Traffic counts](https://community.blackspectacles.com/t/traffic-counts/5940):
>
> not really sure how to read this diagram…can someone explain? This is from NCARB’s practice exam.

I also found a thread in the NCARB Community about this same question, with some additional perspectives:

Hopefully it is reassuring that you are definitely not the only one having difficulty understanding this question! It is a tricky type of question, almost like a puzzle, so it can be hard to wrap your mind around the various considerations to derive the answer.

If you’re still having a hard time understanding this, let me know exactly what you’re struggling with and I can try to help break it down even further!

Best,
