Traffic flow refers to the movement of vehicles and pedestrians on roads and pathways. It is influenced by various factors, including the number of vehicles, road conditions, and traffic signals. Understanding traffic flow helps in managing congestion and ensuring safety for everyone on the road. Efficient traffic flow is essential for urban planning and transportation systems. Traffic engineers study patterns to design better roads and intersections, while smart traffic lights can adjust their timing based on real-time conditions. By improving traffic flow, cities can reduce travel times and enhance the overall experience for drivers and pedestrians alike.
