Method, apparatus, and system for providing in-parking navigation
An approach is provided for in-parking navigation based on mobile device sensor data, the resulted semantic events, and an estimated parking occupancy level. The approach, for example, involves receiving parking information from in-parking navigation system(s) of vehicle(s) and/or mobile device(s) associated with the vehicle(s) traveling in a parking facility with no or a positioning satellite coverage below a threshold. The parking information indicates parking spot location(s) occupied by the vehicle(s). The in-parking navigation system(s) determines the at least one parking spot location based on tracking multi-modal trajectories of the mobile device(s). The multi-modal trajectories comprise vehicle trajectory segment(s) traveling within the parking facility and pedestrian trajectory segment(s) traveling to/from pedestrian entry or exit point(s) of the parking facility. The approach also involves determining an occupancy level of the parking facility based on the parking information. The approach further involves providing the occupancy level of the parking facility as an output. |

Determination and use of cluster-based stopping points for motor vehicles
Technologies and techniques for determining a cluster-based stopping point for a motor vehicle for a predefined reason for stopping in a lane of a road. The individual stopping points of a plurality of vehicles may be determined for the reason for stopping in the lane, wherein the vehicles are controlled by individual drivers. A distribution of the individual stopping points in the lane at least in the direction of travel of the vehicles may be determined. The maximum of the distribution may be determined and stored as a cluster-based stopping point. The cluster-based stopping point determined in this way may be applied to autonomous driving technologies. |

Method for locating a network device in a mesh network and corresponding mesh network
A method for locating a network device in a mesh network includes the steps of: generating a message from a network device; storing a step value and an initial step value in the message; initializing the step value with the initial step value; sending the message to the mesh network; receiving the message is received at a further network device; and determining whether the message is classified as received for the first time. If the message is classified by the further network device as being received for the first time, the following additional steps are performed: adding a delta step value to the step value; determining a distance of the further network device from the network device from the step value changed in this way and the initial step value; and indicating the distance for locating the network device for a user at the further network device. |
