Question

Answer the following question in about 30 words:

Describe the method of constructing a traffic flow map.

Answer 1

To construct a traffic flow map, a base route map connecting different stations is combined with actual movement data. First, a suitable scale is chosen to determine the proportional width of the lines based on the volume of passengers or cargo. Then, straight lines of varying thickness are drawn parallel to the transport routes. The width of these lines directly represents the density and volume of traffic on each specific route.
