New Jersey’s public roads are described and classified in a variety of ways that enable public agencies to keep them safe and maintained. The traffic using these roadways is also categorized for the same purposes.

NJDOT maintains a traffic monitoring program consisting of continuous and short-term elements. The traffic counting program is designed to utilize, at a minimum, 48-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:
– 6,000 Short-Term (48-hour) Count sites
– 90 permanent Weigh-in-Motion (WIM) system sites and
– 95 Traffic Volume System (TVS) sites
To compute AADT, the data collected during the short duration counts “48-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).

– Region 1: Traffic in urban Northeastern New Jersey- New York area that serve major industries, warehousing, trucking, logistics and through-truck movements.
– Region 2: Traffic in rural Northwestern section of New Jersey – Pennsylvania – New York area that serve local truck traffic, agricultural, retail and manufacturing with winter season recreational activities and various camping sites during summer.
– Region 3: Traffic in Central and Southern New Jersey that serve pharmaceutical companies, retail, warehousing, agricultural and through-truck movements.
– Region 4: Traffic serving the NJ shore, recreational and beach activities including fishing, boating and Atlantic City casinos. This region experiences high traffic during summer time and on summer weekends only.
