Abstract: An embodiment of the invention may include a method, computer program product and computer system for managing mobile objects. The embodiment may determine, by a mobile object server, a position of a mobile object in a geographic space managed by the mobile object server. The embodiment may determine a plurality of routes based on the position of the mobile object in the geographic space. The embodiment may calculate, by the mobile object server, a plurality of route parameters for the plurality of routes, wherein the plurality of route parameters includes a passage possibility of the mobile object over each route. The embodiment may calculate a plurality of edge parameters for a plurality of edges, wherein each edge is a segment of a route, and wherein the edge parameter includes the passage possibility of the mobile object over each edge.

Abstract: Position data may gradually pseudonymized by a method, comprising: generating a sequence of relative positions from a sequence of absolute positions of a moving object; randomizing the sequence of relative positions using at least a sequence of random numbers generated from at least one seed; in response to receiving an analytical job comprising the at least one seed, restoring the sequence of relative positions from the randomized sequence of relative positions; and in response to receiving an analytical job comprising both the at least one seed and at least one absolute position derived from the sequence of absolute positions, restoring the sequence of absolute positions from the randomized sequence of relative positions.

Abstract: Event data for at least one moving event is received. From the event data, moving event data indicating a trend of the moving event can be generated. For each of a plurality of vehicles, historical trip pattern data can be accessed and, based on the historical trip pattern data, a probability that the vehicle will be affected by the moving event can be determined. A moving event simulation can be generated based on,at least in part, the historical pattern data and the trend of the moving event. The moving event simulation can predict future locations of the vehicle and the moving event at each of a plurality of future time intervals. Based on the moving event simulation, a determination can be made as to when the vehicle will be affected by the moving event. A notification regarding the moving event can be communicated.
