Traffic volume refers to the number of vehicles that pass a specific point on a road over a given period, usually measured in vehicles per hour or per day. This measurement helps city planners and transportation agencies understand road usage patterns, identify congestion points, and plan for future infrastructure needs. High traffic volume can lead to increased travel times, higher accident rates, and greater wear on road surfaces. Monitoring traffic volume is essential for effective traffic management and can influence decisions regarding traffic signals, road expansions, and public transportation options to improve overall mobility in urban areas.
