Traffic Counts
The NRPC Traffic Count viewer is an ArcGIS Online app with the following functionality:
- Data is available from 2010-present
- Site locations are symbolized by relative volume
- Site ID is displayed and is searchable using the search box
- AM and PM volumes are available
- Dates of the count are displayed
- Counts over time are shown in the chart
- Links to initial field reports are provided

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.
