This data can include information on vehicle volume, speed, congestion, accidents, and other factors that influence traffic patterns. It is typically collected using various technologies such as traffic cameras, sensors, and GPS devices, and is used by transportation agencies to monitor and manage traffic flow, plan infrastructure improvements, and make policy decisions related to transportation and urban planning. Traffic data plays a crucial role in improving traffic safety, reducing congestion, and enhancing overall mobility in urban areas.
