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流量的估算。此值通过对同一路段进行短期计数并据此进行换算得出。由于此过程，任何给定路段的最新AADT估算值将始终对应于上一年度。数据涵盖了所有纽约州道路以及联邦援助系统中的道路。
