    Abstract: Systems and methods for processing geographical zones are provided. The method involves operating at least one processor to: define a bounding box surrounding a geographical zone; iteratively partition the bounding box into a plurality of bounding boxes by, starting with the bounding box in the first iteration: determine whether the bounding box contains more than a predetermined maximum number of vertices; divide the bounding box into two additional bounding boxes if the bounding box contains more than the predetermined maximum number of vertices, repeat the steps of determining and dividing the bounding box for the additional bounding boxes in the next iteration until each additional bounding box does not contain more than the predetermined maximum number of vertices; generate a binary tree data structure representing the geographical zone; search the binary tree data structure to determine whether a vehicle is located within one of the bounding boxes.

    Abstract: A method for collecting transportation vehicle-based data and transferring the data to a backend computer, wherein the respective data sets relate to predefined route sections travelled along by a swarm of data-collecting vehicles, wherein parameterized orders for the acquisition of transportation vehicle-based data are stored in the backend computer and each order includes the parameter of route section, which defines the route section for which transportation vehicle-related data is to be collected; the parameter of swarm size, which defines how many transportation vehicles per unit of time are to collect data for the specified route section; and the parameter time interval, which defines the time interval in which data is to be acquired for the route section. Route-related data is continuously transferred to the backend computer from each transportation vehicle of the swarm, wherein a header constitutes an overview of the transportation vehicle-based data stored temporarily in the transportation vehicle.

    Abstract: A system is provided that may include a first communication controller that may communicate with a vehicle system formed from two or more vehicles. The first communication controller may operate in different modes, including a first mode to control movement of the vehicle system without repeating any control signals communicated between the vehicles, and in a second mode to monitor different frequencies for receipt of the control signals, receive and repeat a first control signal of the control signals at a first frequency, and receive and repeats a second control signal of the control signals at a second frequency. The first communication controller may also operate in a third mode in which the first communication controller may monitor the first frequency but not the second frequency for the first control signal, receives the first control signal at the first frequency, and repeats the first control signal at the first frequency.
