Sometimes I wonder if we've regressed in terms of attention to quality. Here in the US, I see lots of potholes on the streets and sidewalks. Meanwhile, the ancient cobblestone roads are still functional to this day.

Somebody mentioned semis already, but also, I bet Roman engineers would give up immediately if they saw a snowplow.

How can it take 2 months on foot, yet only 1 month per horse, when a horse can only travel between 25-35 miles a day, which is not twice as far as a human can travel in a day, but about equal?

My thought is that one didn't simply travel alone on horseback, but with a group and baggage, and I wouldn't expect servants to be mounted. The animals help with the baggage. You also would want a group since there are highwaymen and freebooters on the road.

I seem to recall oxen speed being about 12 miles per day.

I've been always fascinated by subway maps. The best ones are usually made manually and require update from contractors on every infrastructure extension. Were there any efforts to make autogenerated styled subway maps? Not like stylization of OSM data, but real schemes that show the whole system without sensory overload?

Some examples of automatic layout in this style: - M. Nöllenburg: Automated Drawings of Metro Maps, 2005. We've used that a while ago to render a few pretty images with our graph visualization library, but runtime is prohibitive (along with the requirement of a fast ILP solver). - LOOM: https://github.com/ad-freiburg/loom and https://loom.cs.uni-freiburg.de/global

Wow, cool. Thanks for sharing!

I hope someone builds a web version of Mini Metro with this on top of OSM.

They used to pour molten iron in holes in their cobblestone roads.

The original creator's page is: https://sashamaps.net/docs/maps/roman-roads-original/ The summary here links right to the original content. I just wanted to highlight the original for the sake of other readers clicking through quickly. There's also a much more detailed (and more interesting) writeup on the creator's page.

I actually refer to his list of 20 simple, distinct colors (https://sashamaps.net/docs/resources/20-colors/) which he came up with for this map, pretty frequently. It's a nice palette.

This is really neat! Thanks for sharing. I wonder if there's an analogue for these routes and the roadway system there? I imagine so. I thought it was interesting how short Via Appia was. Learning Latin growing up, I imagined that to be much longer.

An easy trick is to rotate hue with a spacing of 1.618. That guarantees maximum separation with no near collisions for any number of hues.

Horses would often be swapped out at stations when a wealthy person would have to travel very quickly across a long distance. Maybe this is an average since the speed with which horsemen could travel would depend on the rate at which they exchanged their horses.

In an extreme example from the year 9 BC, the future emperor Tiberius traveled on the Roman Roads 330 miles (531 km) between northern Italy and modern day Mainz, Germany in 36 hours without sleep. He was rushing to the deathbed of his older brother Drusus after the latter suffered mortal injuries in a freak horse accident. https://en.wikipedia.org/wiki/Drususstein
