TrafficZoom publishes directional traffic volume data for every road segment in the United States with AADT > 500 vpd: how many vehicles use a road, when they use it, what share of them are heavy vehicles, and drivers' origin demographics.
Built and operated by Ticon, Inc.
The question behind every page here - how much traffic actually passes this location - is asked constantly by site selectors, civil engineers, municipal and transportation specialists and real estate professionals.
TrafficZoom volumes are engineered estimates, not raw counts. Six inputs go into the pipeline documented on our Methodology page.
We validate our estimates against verified measurements performed by traditional counters and state-of-the-art detectors. Across validated locations, the median average percentage error is 11.2%, with a maximum of 20% at a 90% confidence level. We do not publish locations below 300 vehicles per day. Usually, the error is larger on low-volume rural segments and smaller on larger roads, highways and arterials, where the sample is densest.
We publish these numbers because traffic estimates get used for decisions with real money behind them, and a figure without an error bar is not usable. If a number on our site conflicts with a count you have measured, tell us - we’ll verify your measurement and re-run the segment if needed.
