What makes a freight map useful
A plain guide to useful freight map design.
Public freight data is useful when the reader knows its source, coverage and delay before acting on it.
This guide explains the topic in that spirit: what to look at first, what the data can support, and what still needs confirmation from an official or operating source.
The aim is a faster, clearer read of the freight signal, not a claim that one dataset tells the whole story.
