The above maps displays traffic counts (point features) and traffic volume (linear features) associated with County-maintained roads. NOTE: Roads that are within city limits, state highways, or private property do not belong to the County-Maintained Road System.
A traffic count is a field survey that measures of the number of vehicles passing a specific point on a road within a given amount of time, in order to determine the volume of traffic, or Traffic Volume. On the above map, traffic counts are displayed as red point features.
Traffic volume refers to the number of vehicles that pass a specific point or stretch of road within a given amount of time. It is typically expressed as Average Daily Traffic (ADT), which is the number of vehicles per day.
On the above map, traffic volume is displayed as red line features (with graduated thickness based on average volume). For any stretch of road defined on the map, Average Volume is derived from all weekday traffic counts that have been taken within along stretch of road.
