Mobility analytics company StreetLight Data has launched an Annual Average Daily Traffic counting system for what it says is almost every road in North America.
“Annual traffic counts available on-demand for any roadway in the US are a holy grail for transportation planners and engineers,” the company says in a statement. “Historically they have had to task staff or consultants with manually counting, installing equipment or modelling traffic, which isn’t feasible or accurate for understanding road congestion at scale.”
“For most roadways, we collect AADT using temporary traffic count sensors that operate for two to seven days with limited information. Using advanced modelling techniques, we turn a few days of real-world data into an estimate of average daily traffic for an entire year,” explained Stephen S Yoon, Senior Regional Planner at SCAG, the largest metropolitan planning organisation in the US. “Unfortunately, most public agencies lack the resources to install and maintain permanent counters on every roadway they want to measure.”
“We measure and analyze the movements of millions of vehicles across 4 million miles of U.S. roadway, collecting and processing 365 days of traffic data,” added Laura Schewel, CEO and co-founder of StreetLight Data. “Years of fine-tuning our proprietary algorithms, powered by machine learning and deep mobility analytic techniques, give our 2017 AADT metrics unmatched accuracy.”
The company says diversity and accuracy of data feeding its algorithms are a “key competitive advantage”. They include 365 days of data from over 65 million smart phones, connected cars and connected trucks, as well as census data, road network information, and more.
