Traffic Volume Counts
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
- 50 Major Station Site

Short Duration Counts
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).
Adjustment Factors by Region:

Traffic in urban Northeastern New Jersey- New York area that serve
major industries, warehousing, trucking, logistics and through–truck movements. |

|
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. |
