A line is drawn along the road, or from the country of origin to country of destination, proportional in width to the volume of the flow.

Flow maps can be divided as radial, network, and distributive. Flow lines = indicate a line of movement with its thickness representing the volume of movement and direction the line of flow. Describe the direction and magnitude of the various movements of the geographic phenomena between different areas of the map.
