Proven metrics, used in all contiguous United States* and Canada
Used in all top 25 MSAs in the U.S. and top 15 MSAs in Canada, StreetLight’s data has been validated against public, external sources incl. permanent sensors, household surveys, license plates, bluetooth scanning, and the Census. Additional validations with clients and partners using private data also support the quality of our Metrics.
* Projects in all lower 48 states;
Data not available in Hawaii and Alaska
Monthly transportation analyses
Coverage of Traffic Analysis Zones
Vehicular Metrics validation
Our AADT metrics have been validated by 3,000+ permanent counter data points across the U.S. with an R2 of .98 and 2,500+ permanent counter data points across Canada with an R2 of .97. StreetLight’s AADT values correlate very closely with AADT values from permanent counters.
Bike and pedestrian Metrics validation
Our metrics continue to be validated repeatedly against ground-truth data from permanent bike and pedestrian counters across the country, both independent public and private data sets, including counters from both roads and trails. For both bike and pedestrian data we see high R² values.
Peruse our methodology and validation library
Reliable Big Data metrics depend on complex machine learning that trains StreetLight’s proprietary algorithms, with validation a critical component of wide adoption.
We invite you to explore our whitepapers, share them with your stakeholders, and take part in our journey to bring on-demand empirical data to North America’s transportation decisions.
