World Transportation Patterns
Summary
This map shows the major transportation patterns around the world on both land and water. Ocean shipping routes are indicated with arrows that are proportional in width to the tonnage of cargo carried, while land transport routes are indicated by shading of all areas that are within 20 miles (32 km) of roads, railroads, or inland waterways.
