STREETLIGHT AADT
StreetLight AADT covers nearly every road in the U.S. and Canada, providing traffic estimates for all road segment types, including highways, low-volume, and recently developed roads. Get more granular monthly and hourly All Vehicles traffic counts split by vehicle weight categories for historical time periods. Our on-demand metrics include:
- AADT (Annual Average Daily Traffic)
- AAHT (Annual Average Hourly Traffic)
- MADT (Monthly Average Daily Traffic)
AADT 2023 for the U.S. is available
GET STARTEDREAD CASE STUDYStreetLight was contracted by the Federal Highway Administration to
investigate how Big Data can be used to estimate AADT
StreetLight collaborated with FHWA, 18 state DOTs, and academics to evaluate how Big Data can significantly reduce AADT costs to state DOTs and MPOs and improve coverage of up-to-date traffic counts. Results from this study informed StreetLight’s AADT methodology.

Defensible and validated AADT metrics help accelerate mobility projects
Over the past few years, Departments of Transportation (DOTs) in the U.S. have used StreetLight’s AADT metrics to meet their reporting requirements, including the Highway Performance Reporting System (HPMS). Cities and MPOs can utilize AADT metrics to fill data gaps and boost their infrastructure grant applications. With AADT metrics, you can:
TRADITIONAL AADT
BIG DATA AADT
Limitations of traditional methods
- Time-consuming process of data collection, analysis, and approval
- Expensive
- Lack of geographic coverage and seasonality issues
- Safety hazards with staff in the field
- Fails to capture seasonal traffic
Benefits of StreetLight AADT

StreetLight AADT Validation
- StreetLight’s latest AADT Metrics are validated with nearly 1,724 unique permanent counter locations across the U.S. and 2,500+ permanent counter data points across Canada
- R2 of 0.98 for the U.S. and R2 of 0.97 for Canada
- StreetLight’s AADT values correlate very closely with AADT values from permanent counters

Fill Data Gaps where Traffic Counters Fall Short
When traditional traffic counters and surveys fail to capture the nuances of ever-changing traffic trends, transportation analytics can fill that gap and add richness to transportation planning and modeling.
