Systems and methods for airspace demand prediction with improved sector level demand prediction are provided. In one embodiment, an air traffic demand prediction system () operable to predict demand within an airspace divided into sectors includes an expanded route predictor () operable to generate predicted two-dimensional expanded route information () associated with at least one requested flight (), a trajectory modeler () operable to generate predicted four-dimensional expanded route information (), a sector crossing predictor () operable to generate predicted sector crossing information (), a departure time predictor () operable to generate predicted departure time information (), and a demand modeler () operable to generate a demand model (), the demand model () including predicted time intervals associated with the at least one requested flight indicating when it is expected to be present within one or more sectors of the airspace.

Air traffic demand prediction

A computationally efficient method and system of finding intersections of a three-dimensional path (e.g., an airpath) through a three-dimensional space (e.g., an airspace) partitioned into multiple volumes. In one embodiment, such a method includes determining whether a current point of a current segment of the path is included within one of the volumes, establishing such volume as a current volume, determining whether a boundary of the current volume is intersected by the current segment, setting the intersection point as an exit point of the path, adjusting the current point of the current segment to the exit point, identifying a volume adjacent to the current volume that includes the exit point, changing the current volume to the adjacent volume, and setting the current point of the current segment as an entry point of the path.
