The Central New Hampshire Regional Planning Commission is involved in many aspects of Transportation Planning in 18 municipalities in Merrimack County and 2 municipalities in Hillsborough County. Primarily we serve our member towns with plan reviews, transportation chapters, traffic count data, turn movement analysis, speed movements, bicycle level of service (BLOS), pedestrian level of service (PLOS), intersection analysis, transportation demand management (TDM) services and Safe Routes to School Support. CNHRPC also participates in statewide transportation planning efforts, corridor studies and coordinated transit studies with neighboring planning commissions. Visit the Transportation Advisory Committee (TAC) page to learn more about our role as the region's transportation planning organization.

Each year, CNHRPC performs traffic counts in our member communities. To download a spreadsheet of all traffic counts performed from 1992 through 2009, click here.
