    Abstract: Systems and methods for optimizing traffic flow through an intersection are disclosed. In an embodiment, the method includes receiving positional data indicating a current location of a first vehicle intending to pass through the intersection, receiving directional data indicating an intended direction of the first vehicle through the intersection from the current location, determining, based on the positional data and the directional data, whether an intended path of the first vehicle through the intersection interferes with an alternative path through the intersection, and adjusting a traffic signal at the intersection to decrease an amount of time to pass through the intersection via the alternative path.

    Abstract: A vehicle drivable area detection system includes a vehicle, at least one 3D sensor and an electronic controller. The at least one 3D sensor is installed to the vehicle and is configured to scan and capture data using laser imaging, detection and distance ranging relative to the vehicle. The data collected represents ground surface features including vertical obstacles, non-vertical obstacles and a drivable area proximate the vehicle within a line-of-sight of the 3D sensor. The electronic controller is installed within the vehicle and is electronically connected to the 3D sensor and at least one driver assist component. The electronic controller conducts the following: a vertical obstacle extraction from the data; terrain estimating from the data; curb detection from the data; and generating a plurality of data elements identifying vertical obstacles including curbs and the drivable area to the at least one driver assist component.

    Abstract: A vehicle data display system includes an electronic display installed within a vehicle, a 3-D sensor and an electronic controller. The 3-D sensor configured to scan areas forward of and along lateral sides of the vehicle producing point cloud. Each data point of the cloud data corresponding to a surface portion of a physical feature. Each data point includes distance, direction and vertical location of each surface point. The electronic controller is connected to the electronic display and the 3-D sensor. The electronic controller receives and evaluates the point cloud from the 3-D sensor generating a 3-D model of detected ones of the physical features around the vehicle including ground surfaces, non-drivable features and driving limiting features relative to the vehicle. The non-drivable features are features that have predetermined geometric relationships with adjacent ground surfaces such that caution is to he taken when driving over or on driving limiting features.
