In March, 2015, RoadBump was used to record a 19 mile stretch of highway in central Arkansas. This section of road had recently been measured by the Arkansas Highway Department using their ARAN van. The results from the RoadBump test showed a tight correlation in the IRI graphs and achieved an overall IRI rating within 2% of true with no section being off more than 7.5%.
