Abstract:

For this validation study, NREL compiled traffic volume data from permanent traffic counters at over 500 locations across the U.S. These data were used to validate annual average daily traffic (AADT) estimates developed by Streetlight Data using passive data sources. The analysis revealed a strong correlation between estimates derived from passive sources and the permanent counters. However, statistical differences were observed, and deviations from ground truth may be unacceptable for some applications. Toll locations were particularly prone to high errors, possibly due to complex geometry. While the validation sheds light on the utility of AADT estimation from passive sources, its findings were limited by a lack of permanent counter data. It is possible that an analysis using a larger sample size could result in more robust findings.
