Traffic volume data is the backbone of infrastructure planning, safety analysis, and freight operations — yet for most of the U.S. road network, it simply doesn’t exist. Official counts from the FHWA’s Highway Performance Monitoring System cover only a fraction of roads, arrive 12 to 24 months late, and offer little insight into how commercial vehicle volumes vary by weight class or geography.
Our latest methodology white paper, Full-Network Traffic Volume Estimation: Altitude AADT Modeling Methodology, details how Altitude by Geotab closes this gap at scale. By combining Geotab’s first-party commercial fleet telematics with supervised machine learning and publicly available geographic and demographic data, the model produces segment-level AADT estimates for every major road in the contiguous United States — including roads that have never carried an official count.
This isn’t just an improvement on existing data — it’s a new foundation for decisions that previously had to be made in the dark.
Get the report to access critical data supporting your planning efforts:
- Delivers Universal, Medium, and Heavy estimates: Unlike any other commercially available product, Altitude provides separate AADT values for Heavy (GVWR Classes 6–8) and Medium (GVWR Classes 3–5) commercial vehicles alongside total traffic — enabling freight corridor planning and bridge loading assessments grounded in real fleet behavior.
- Closes the coverage and latency gap: Time series forecasting using Chronos reduces data latency from 12–24 months to three months, so planners are working with estimates that reflect current conditions — not traffic patterns from two years ago.
- Quantifies what you don’t know: Every estimate ships with a calibrated 90% prediction interval, disaggregated by road type and volume level, so analysts can apply appropriate confidence to every number they act on.
The road network doesn’t wait for annual data releases. Neither should the decisions that depend on it.
