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算。此值通过在同一路段上进行的短期计数计算得出，然后经过换算以产生AADT的估算值。由于此过程，任何给定路段的最新AADT数据始终对应于上一年度。数据涵盖纽约州所有路线以及联邦援助系统中的道路。
