Traffic Count Information

The Suffolk County Department of Public Works collects two types of traffic volume count information on its road network:   24-hour/7-day directional counts using automated traffic recorders, and manual intersection turning movement counts.

  •     The 24 hour counts are factored to represent the Average Annual Daily Traffic (AADT) which travels on a given section of road each day.
  •     Turning Movement counts show all vehicle movements through an intersection only during specific peak hours of the day.
