Abstract: Systems and methods for identifying an operating characteristic in a commodity transport network model may involve displaying a scaled map of a region; receiving flow information corresponding to a user-selected object displayed on the map; and, using the flow information, identifying the operating characteristic. Systems and methods for representing an event in a display of a planning project analysis computer system may involve representing on the display a scaled map of a region; and displaying on the display an indication of the event. The indication may designate a position in the display that corresponds a location of the event.
