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. Hourly data is available for short-duration counts SDC as well as the continuous count sites CCS from to the current year. Intersection counts display and report leg movements and summary information.
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.
