NJDOT maintains a traffic monitoring program consisting of continuous and short-term elements. The traffic counting program is designed to utilize, at a minimum, hour short-term counts to produce estimates of Annual Average Daily Traffic AADT. Traffic Counts are taken in all type of public roads statewide at the following locations:. To compute AADT, the data collected during the short duration counts "hour periods" must be adjusted to annual conditions. These adjustments include: axle correction for counts made with single axle sensors ; day-of-week for counts taken for less than one week ; seasonal to account for changes in volume that occur from one time of year to another ; time-of-day for counts taken for less than 24 hours.

Traffic Monitoring is responsible for the collection of all types of traffic data including traffic volumes, vehicle classification, turning movements and special studies as requested by the Department. The reporting of traffic volumes is accomplished through two distinct methods involving the Continuous Count and Coverage i. The Continuous Count Program consists of 71 permanent recorder sites located throughout the state, monitoring traffic volumes days per year on an hourly basis. Additionally, 20 of these sites classify the vehicles into 13 categories as required by the Federal Highway Administration. Traffic count and vehicle classification data are collected for 24 hours utilizing road tubes and adjusted to an Annual Average Daily Traffic AADT volume.

AADT is different from ADT because it represents data for the entire year. Under the simple average method, AADT is estimated as the total traffic volume passing a point (or segment) of a road in both directions for a year divided by the number of days in the year. It requires volume for every day of the year.
