Traffic flow refers to the movement of vehicles and pedestrians on roads and pathways. It is influenced by various factors, including road design, traffic signals, and the volume of vehicles. Efficient traffic flow helps reduce congestion and improves safety for all road users. Understanding traffic flow is essential for urban planning and transportation management. Traffic engineers study patterns and behaviors to optimize road systems, ensuring that commuters can travel smoothly. By analyzing data, they can implement changes that enhance the overall efficiency of transportation networks.
