Traffic Counting Program

The Engineering Division performs traffic counts on a regular basis on most Town streets to monitor traffic volumes and to help understand how growth of the Town is affecting traffic patterns. 

Current and historical traffic count data reported as Average Annual Daily Traffic (AADT) is available on the Town's GIS Website by clicking this link below.  The map by default displays the most recent counts.  Select the Identify Button and choose the count location on the screen to review historical counts at the same location.

The typical frequency of traffic counts performed by the Town is based on the street classification described in the table below.

Street Classification 

Traffic Volume (veh/day) 

Traffic Count Frequency

Arterial greater than 3,000  Every 3 years
Collector 1,500 to 3,000  Every 5 years
Local     500 to 1,500  Every 10 years or as needed
Light Local 200 to 500  as needed
Limited Local    0 to 200  as needed*

* Note that traffic counts are not performed on streets with less than 10 residences due to the very low traffic volumes.
