To find the quietest road in each US state, Geotab gathered the latest available (2015) traffic count data from the Highway Performance Monitoring System. Quietness was calculated as the annual average daily traffic, and routes with the lowest in each state were deemed the quietest. The data covers Interstates, US Routes, and State Routes over 10 miles long.
The most scenic routes listed are subjective and the opinion of landscape photographer James Q Martin.
