Are there accounts of traffic in the ancient world written in Latin? By traffic I mean the behaviour of various vehicles1 on roads and in intersections, not masses of pedestrians. If there are multiple mentions of this in the extant classical literature, what is the longest passage on this topic?
For some reason I ended up looking for ways to describe modern car traffic in Latin, and a passage on the analogous topic in the ancient world would help find useful phrases. In addition, I know almost nothing about ancient traffic, and I would like to get a better picture.
1 The concept of "vehicle" might not be well-defined, but I hope the intention is clear enough. If you want a definition, I would say a vehicle always has wheels and preferably bigger than a wheelbarrow. But if there is a great passage about horses or wheelbarrows in traffic, it would still be interesting.
