Traffic Counts

The Division of Public Works is responsible for collecting traffic counts on the county road system, which assists in identifying trends and prioritizing improvements. The counts are taken with machines, which are typically in place for 2-3 days in the middle of the week. The numbers are referred to as the Average Annual Daily Traffic (AADT), which reflects the amount of traffic in both directions for a 24-hour period. Please keep in mind there may be seasonal and temporal variations in traffic levels. For more information:
