How can I input a network of streets and create the shortest path to cover the entirety of the network?

Seems pretty straightforward and that I should be able to do such in Network Analyst, Linear Referencing and/or Create Routes, but I am having trouble figuring it out. Any help would be appreciated. Thank you!

Not really that easy.  For instance, can you retrace a road segment?  Do you have an origin? (which can affect the path).

Perhaps you can elaborate on your end goal further.

Hey Dan! I am trying to calculate the shortest path to cover a network of

roads for running, so it can be bidirectional or repetitive where

necessary. I have learned that it is called the Chinese Postman Problem.

Thanks for your response and consideration of the issue!

Are you talking about what is commonly known as the Chinese Postman Problem?  If so, last time I checked, the ESRI network analyst extension didn't solve for it. I'll give a shout out to and old friend and collegue Jay Sandhu‌, perhaps he can fill in the details.

Hey Joe! Yes, I have learned that it is the Chinese Postman problem. I am

amazed that there is not a tool for it, but I guess depending on the size

of the network, it could be incredibly complicated. Thanks for your

response and further looking into it!
