For the ninth consecutive year, StreetLight delivers industry-validated U.S. AADT 2025 metrics for nearly every roadway, including highways, rural roads, low-volume roads, and more. This year, StreetLight released AADT 2025 just three months after year-end — delivering early validated annual traffic counts to support timely infrastructure investment and FHWA reporting (MIRE and HPMS). StreetLight’s AADT 2025 estimates strongly correlate with ground-truth AADT counts, with a best-fit line’s r-squared of 0.98 and outperform updated FHWA target accuracy benchmarks across all 12 categories.
