Travel time reliability

Travel time reliability measures how steady truck travel times stay on a corridor, computed by FHWA from NPMRDS probe data alongside average travel times and bottleneck delay.

Monthly refreshes feed dashboards and the annual Freight Mobility Trends Report.

In this catalog it appears concretely: - FHWA programme delivers average truck travel times, reliability and bottleneck delay measures on the National Highway System and freight-significant corridors. - npmrds, truck probe, travel time reliability, congestion, performance measures.

Conventions decide whether two sources can be joined at all. Buy one side of an analysis that ignores this convention and every reconciliation step — calendar alignment, unit conversion, entity matching — lands on your team instead of the vendor's.

The failure mode is concrete: the label appears in a listing, the delivered files tell a different story, and the gap surfaces mid-project when fixing it is most expensive.

You rarely have to take a vendor's word for it. 82.4% of the 1,744 datasets Datadory catalogs are free to access, and FHWA programme delivers average truck travel times, reliability and bottleneck delay measures on the National Highway System and freight-significant corridors lets you inspect the real artifact before any budget is committed.

Treat every claim of this attribute as testable:

1. Open FHWA programme delivers average truck travel times, reliability and bottleneck delay measures on the National Highway System and freight-significant corridors and compare its listing against the delivered artifact before paying for a commercial equivalent.
2. Open npmrds, truck probe, travel time reliability, congestion, performance measures and compare its listing against the delivered artifact before paying for a commercial equivalent.
