San Francisco, Calif. –– StreetLight Data, Inc. announced a breakthrough in urban, suburban, and rural planning that it said delivers dramatically more accurate, representative and dynamic traffic data. StreetLight Data’s new Average Annual Daily Traffic (AADT) offering also cuts traditional measurement costs by more than 50 percent, the company said, saving local, state and federal agencies, as well as consultant planners hundreds of thousands to millions of dollars on critical programs.

The AADT number is an industry standard that estimates the average number of vehicles on a road per day. It is a crucial metric to planners looking at infrastructure, business, housing or even retail development. However, traditional solutions used to estimate AADT suffer from stale and static data, short measurement periods, mechanical failure, high costs and gross rather than granular estimates.

According to StreetLight Data, its new AADT Metrics are:


  • Results based on a full year of travel data, not, two days.
  • Uses multiple types of locational Big Data. These are run through StreetLight Data’s proprietary algorithmic processing engine, Route Science.


  • 50 percent or greater savings over traditional AADT project costs.

Dynamic and easy to rollout

  • No sensor deployment, maintenance, or operations.
  • No extra analysis or scaling.
  • With just a few mouse clicks, AADT data are available on the StreetLight InSight platform.

“Traffic counts are critical to numerous decisions in transportation, from planning, designing, operating, managing, and monitoring performance,” said Shawn Turner, Senior Research Engineer, Texas Transportation Institute, the largest transportation research institute in the U.S. “New mobile device-based approaches are poised to change the way we have collected traffic counts for the past 50-60 years. Soon, 1- or 2-day manual traffic counts may be as obsolete as hand-cranked car windows and bench seats.”

“StreetLight Data is dedicated to providing government and private sector planners significantly more accurate information and analytics for both the large and small projects they are considering,” offered Laura Schewel, CEO and co-founder of StreetLight Data. “With the release of our new AADT Metrics, we will save planners considerable time and money, while also better informing their vital development decisions.”

At the center of StreetLight Data’s offerings is StreetLight InSight, an easy-to-use online platform for running Metrics directly from a computer’s Internet browser, in just a few mouse clicks. The StreetLight InSight platform lets customers ask and answer specific questions about travel patterns.
