Traffic flow analysis is the study of how vehicles move on roads and highways. It involves collecting data on vehicle speeds, densities, and travel times to understand patterns and identify congestion points. This analysis helps in planning and improving road infrastructure, ensuring safer and more efficient travel. By using tools like traffic cameras, sensors, and GPS data, traffic flow analysis can provide insights into peak travel times and the impact of road conditions. This information is crucial for city planners and transportation agencies to make informed decisions about traffic management and urban development.
