SWRPC Traffic Counts

NH DOT and the nine regional planning commissions conduct a traffic counting program throughout the state. NH DOT maintains permanent automatic traffic recorders which measure traffic volumes on a daily basis at selected locations. Seasonal counts are conducted on an annual basis by regional planning commissions at locations selected by NH DOT from an existing set of sample points on state and local roads. SWRPC typically collects 7-day counts at one third of the 335 locations in the Southwest Region.

Select town:    

Seasonal traffic volumes are collected using automatic traffic recorders (via the black tubes you may see stretched across the road in the summer). The 7-day samples are adjusted for seasonal traffic variations and percentage of truck traffic - reported as Average Annual Daily Traffic (AADT). NH DOT publishes the seasonal and permanent traffic volume data in their annual Traffic Volume Report.
