traffic density

Traffic density refers to the number of vehicles occupying a specific stretch of road at any given time. It indicates how crowded a roadway is—low density means few cars, allowing smooth movement; high density indicates many vehicles, leading to congestion and slower traffic flow. It's an important measure used to assess transportation efficiency, plan infrastructure, and manage traffic to reduce delays and improve safety. Essentially, traffic density helps us understand how busy a road is and how it affects travel conditions.
