Overview

Administrative network analysis reveals expanding freight volumes alongside spatial concentration in departmental transit, suggesting cargo weight diverges substantially from trip counts.

Key Points

To assess territorial and functional concentration patterns and directed network structures in Colombian road freight dispatches across distinct measurement units and directional flows.
Analyzed nationwide records from the National Registry of Road Freight Dispatches (RNDC) from January 2022 to December 2025, covering 8,176,619 aggregate source rows representing 46,969,693 trips.
Evaluated trip counts and mass-recorded tonnes using raw and normalized Herfindahl–Hirschman indices, Shannon entropy measures, month-resampling, leave-one-month-out diagnostics, and directed network density and reciprocity.
Represented trips increased by 28.8% (from 10.28 to 13.24 million) while mass-recorded freight rose by 11.6% (from 135.76 to 151.52 million tonnes) over the four-year period.
Directed network density ranged from 0.827 to 0.841, binary reciprocity spanned 0.939 to 0.954, and weighted reciprocity was lower at 0.643 to 0.701.
Trip-versus-tonne concentration rankings showed Spearman correlations of 0.535 to 0.823 with departmental rank differences reaching up to 26 positions.
