Abstract: Computer system, method and computer program product are provided for supporting an operator to control a traffic system including a traffic infrastructure configured to allow the movement of real world traffic participants. A state prediction module of the computer system determines, based on time-stamped location data of trajectories, time dependent speed profiles, time dependent turn probabilities, and time dependent attraction shares corresponding to time dependent turn probabilities. It further determines a state forecast (FC1) for a given future time point based on the time dependent traffic parameters including the speed profiles, turn probabilities, and attraction shares), in conjunction with at least one existing time-dependent origin-destination-matrix and a suitable Sequential Dynamic Traffic assignment methodology.

Abstract: A computer system, method, and computer program product, for detecting a stay of a vehicle. The computer system includes an interface component configured to periodically receive location data sets (211-1 to 211-n) from one or more location sensors attached to the vehicle. The system further includes a motion detection component configured to detect a stop of the vehicle when at least two consecutive location data sets (211-1, 211-2) represent the same physical location within a tolerance range to define a stop location of the vehicle.

Abstract: Data indicative of an instantaneous location, a destination and a route from the instantaneous location to the destination are transmitted from a motor vehicle navigation unit to a central unit. Traffic information about the route between the instantaneous location and the destination are transmitted from the control unit to the vehicle unit. The received traffic information data are used by the vehicle unit to determine a desirable route between the instantaneous location and the destination given the traffic information. The data of the route thus determined are made available to the vehicle driver, so that he is able to steer toward his desired destination along this specified route.
