Abstract: Disclosed herein is a method for generating a model that can be used by a routing module to determine estimated travel times for routes within a navigable network. The model is generated by a process of machine learning with training data that is obtained from historic positional data recorded by devices travelling within the navigable network. The model can be updated over time as new positional data is obtained. The newly obtained positional data is also used for evaluating the performance of the model and for detecting so-called ‘pattern-breaking’ events where the underlying conditions in the navigable network suddenly change such that the previous version of the model may no longer give accurate estimated travel times.

Abstract: The invention relates to a method for producing a cable tray component which is made of metal and designed, for example, as a cable tray (1) or cable tray cover and has a sequence of beads (5) along its longitudinal extent, which beads are stamped into the workpiece (14) used to form the cable tray component (1) by means of a stamping process, wherein, for the process of bead stamping, the workpiece (14) is clamped in a hold-down element (N) adjacent to or in the transition to a bead (5) to be created. A special feature according to a first embodiment of the method is that the workpiece (14) is held in the hold-down element (N) by a form fit which acts in the radial direction towards the bead (5) to be created and is produced by at least one form-fitting edge (16, 17) pressed into the surface of the workpiece (14), as a result of which at least one indentation following the shape of the bead (5) is introduced into the material of the workpiece (14) by the hold-down element (N) before the bead (5) is formed.

Abstract: Embodiments of the present invention provide a one-to-many route searching method comprising searching map data to select links to form a plurality of routes from a departure node according to a cost function, and determining an extent of each route according to an objective function, wherein the searching of the map data is performed to a search boundary based upon a cost of an unreachable node.
