Color representations (positive values in red, negative values in blue) of the first two factorial coordinates of stops, obtained from Correspondence analysis (CA) performed on the transportation matrix \(\textbf{N}\). Top row maps stops as “origin profiles” (“where passengers are going”), bottom row maps stops as “destination profile” (“where passengers are coming from”). Left column depicts the first factorial dimension, right column the second factorial dimension. Ring sizes correspond to the number of embarkments (top) and disembarkments (bottom)
