TIRTL truck movement and freight corridor maps
These map products turn the TIRTL truck movement layer into public-facing spatial intelligence:
a site-heading truck movement dashboard and a Version 1 freight corridor line map.
Important terminology:
Vehicle movements and truck movements are classified TIRTL sensor movement records / passings. They are not counts of unique vehicles or unique trucks.
Freight corridor map note:
The freight corridor map is a Version 1 monitored-corridor approximation. It connects measured TIRTL site-heading locations into inferred corridor lines. It is not yet a road-centreline-snapped engineering map.

Corridor line features
GeoJSON line features generated from measured TIRTL points.
Open the interactive maps
These are best opened as full-page maps rather than embedded directly, to keep the main intelligence page fast and stable.

Next map upgrade
The next major improvement is road-centreline snapping: matching TIRTL site-heading records to a proper road centreline layer,
then styling actual road segments rather than inferred point-to-point corridor lines.
