Traffic data refers to the information collected about the movement of vehicles and pedestrians on roads and highways. This data can include the number of vehicles, their speed, and the time of day when traffic is heaviest. It helps city planners and transportation agencies understand traffic patterns and make informed decisions about road improvements and traffic management. Traffic data is often gathered using various technologies, such as traffic cameras, sensors, and GPS devices. Analyzing this data can lead to better traffic flow, reduced congestion, and improved safety for all road users.
