Annual Average Daily Traffic (AADT): Beginning 1977

Annual Average Daily Traffic (AADT) is an estimate of the average daily traffic along a defined segment of roadway. This value is calculated from short term counts taken along the same section which are then factored to produce the estimate of AADT. Because of this process, the most recent AADT for any given roadway will always be for the previous year. Data is available for all New York State Routes and roads that are part of the Federal Aid System.

年度平均每日交通流量（AADT）是对指定路段上平均每日交通量的估计。此值通过计算在同一路段上进行的短期计数得出，随后通过换算得出AADT的估计值。由于这一过程，任何给定路段的最新AADT数据都将对应于上一年。数据涵盖了纽约州所有路线及联邦援助系统中的道路。
