Each year, NRPC conducts well over 100 traffic counts at locations throughout the region. This data is used both by NRPC and New Hampshire DOT to generate reports that assist in decision making by local and state officials. NRPC also uses count data to calibrate and validate its traffic modeling program. The NRPC Traffic Count viewer is an ArcGIS Online app with the following functionality:
Please note: most volumes represent 24-hour raw data averages for the 5-weekday period (Mon-Fri); these are raw counts, i.e. they are not adjusted for for truck traffic, seasonal variation, or other factors. Historical count data from 1991-2009 is on file at NRPC and available by request.
