Multidimensional time in transportation

There are many examples of two-dimensional time maps in transportation, although the authors do not acknowledge the multidimensionality of time in their maps. Let’s start with a map of New York travel times on commuter rail which shows the travel time in minutes from Manhattan to commuter rail stations during the evening rush period. The distances on the map match travel times rather than travel distances.

A second map shows travel times for trains from Paris (stunden means hours). Another gives travel times in Paris under three modes of transportation (in minutes). Another shows isochronous travel from Paris, between 2 hours to 15 hours long.

This website shows time-space maps with railway times in Europe and a series of maps showing a day’s journey through history. Here are two travel time contour maps of Atlanta (15 minute contours).

All these maps show two dimensions of time. Can you see it, too?
