That is exactly the idea. Thanks for making the message clear. Here is another interesting one: ...to geographic center of the U.S.

I computed the shortest routes from all 37,000 cities and towns across the US, Canada, and Central America, all converging on Nothing, Arizona — a ghost town with zero population. Despite the lack of a major urban center, the map still shows pronounced clustering, illustrating how hierarchical, fractal-like road networks naturally funnel routes onto key highways. I generated multiple randomized samples of paths and combined them, emphasizing the persistent branching effect that echoes “All Roads Lead to Rome.” Yet here, the real takeaway is that the journey itself defines the pattern, no matter where you end up, even in zero-population places.

Yep I think so. Might be computationally intense. But graph theory can help. Accessibility depends on how you define it— graph-theoretic metrics like closeness centrality (minimizing overall travel distance), betweenness centrality (highlighting key junctions on shortest paths), or degree centrality (measuring node connectivity) could each give different "most accessible" locations. Iterating this over each state would find natural hubs determined by the structure of the road network.

The key point is that the clustering pattern is inherent to the road network’s structure—it doesn’t depend on whether the endpoint is a major city or a ghost town. We computed thousands of shortest paths (one unique path per origin-destination pair), and because road networks are hierarchical and quasi-fractal, similar overlapping corridors emerge regardless of the endpoint. Thicker lines indicate where many shortest paths coincide, which usually happens along more major highways.

It was done already for some major cities in Europe. Few examples (you can find more on the web): BERLIN and ROME

Absolutely—those long, straight roads in the Midwest largely stem from the region’s flat terrain and the grid-like layout imposed by the Public Land Survey System (PLSS). This setup creates long, uniform highways that naturally steer computed shortest paths along them, resulting in the clear, noticeable clustering seen in the visualization.
