Aggregating lines, Part I

Tutorial on aggregating lines in R for transport analysis

Part I of a series on aggregating lines in R for transport planning.

Overview

When working with route networks, you often need to aggregate multiple lines into single segments. This is useful for: - Calculating summary statistics - Visualizing flows - Simplifying networks

The stplanr package provides functions for this, particularly overline() which aggregates lines by geography.
