The traffic monitoring system is designed to collect, analyze, and visualize real-time data about traffic flow in urban areas. The system architecture typically includes several interconnected components that manage traffic sensors, data analysis, and user interfaces. A data flow diagram (DFD) serves as an effective tool to map out the interactions between these components and how data moves through the system.

At the core of the DFD, the traffic data is captured by various sensors deployed on roads, such as cameras, speed radars, and inductive loop detectors. These sensors feed data into a central processing unit where the information is processed and analyzed. The results of the analysis are then presented to traffic management authorities through a dashboard interface for decision-making.

  • Traffic Sensors: Collect real-time data on traffic volume, speed, and congestion.
  • Data Processing Unit: Analyzes raw sensor data and generates traffic reports.
  • User Interface: Displays processed information for traffic monitoring and management.

Data Flow Diagrams help to visualize the movement of information within a system, allowing for a clear understanding of interactions and dependencies between different components.

The following table illustrates the flow of data through the system:
