Abstract: Systems and methods for a model for estimation of reliability of a hazard sensor observation at a vehicle are disclosed. An example apparatus may include a hazard observation interface configured to receive one or more hazard observations from the hazard sensor of the vehicle, wherein each of the one or more hazard observations is associated with a hazard location and a hazard timestamp, a ground truth module configured to determine ground truth data from one or more weather records from a historical weather database based on the hazard location and the hazard timestamp, and a model configured to perform a comparison of the one or more hazard observations to the one or more weather records, the model trained for estimation of reliability of the hazard sensor observations based on the comparison of the one or more hazard observations to the one or more weather records.

Abstract: Systems and methods for a model for determining reliability of hazard sensors associated with vehicles are described. An example method includes receiving hazard observations collected from at least one hazard sensor, wherein the hazard observations is associated with hazard locations, receiving weather data associated with the hazard locations, performing a comparison of the hazard observations to the weather data, identifying a quantity of ground truth matches in which the hazard observations match the weather data based on the comparison, identifying a quantity of false negatives in which the weather data are mismatched with the hazard observations based on the comparison, and calculating a recall value from the quantity of false negatives and the quantity of ground truth matches.

Abstract: Embodiments described herein may provide a method for generating a local hazard warning boundary and at least one confidence band therein. Methods may include: receiving a plurality of probe data points from a plurality of probes within a region, where each probe data point includes location information and an indication of a hazardous condition; generating, based on the plurality of probe data points, a boundary within the region identifying an area within which the hazardous condition is determined to exist with at least a first degree of confidence; generating, based on the plurality of probe data points, a confidence band within the boundary within which the hazardous condition is determined to exist with a second degree of confidence; and providing for an indication of the boundary and the confidence band to at least one of an autonomous vehicle control or to a driver assistance system.

Abstract: Embodiments described herein provide a method for using one or more audio signals from one or more sensors to establish the presence and severity of precipitation at a particular location. Methods may include: receiving at least one first audio signal from a first audio sensor of a vehicle; extracting acoustical features including frequency and amplitude from the at least one first audio signal; receiving at least one second audio signal from a second audio sensor of the vehicle; extracting acoustical features including frequency and amplitude from the at least one second audio signal; processing the frequency and amplitude from the at least one first audio signal and the frequency and amplitude from the at least one second audio signal as inputs to an algorithm to generate an output from the algorithm; and determining, from the output of the algorithm, a precipitation condition and a confidence measure of the precipitation condition.

Abstract: An apparatus autonomously operates at least one system of a vehicle as the vehicle navigates along a route through at least a portion of a traversable network in a sensor-based navigation mode. The apparatus obtains a map fragment corresponding to an area along the route; and, responsive to determining that the vehicle is located within the area, autonomously operates the at least one system of the vehicle as the vehicle navigates a portion of the route within the area in a map-based navigation mode using map data of the map fragment. Responsive to determining that the vehicle has exited the area, the apparatus autonomously operates the at least one system of the vehicle as the vehicle continues to navigate along the route in the sensor-based navigation mode. The map fragment is a portion of a high definition map configured to enable map-based autonomous vehicle navigation/control.

Abstract: A method, apparatus and computer program product for determining a reduced visibility event warning are described herein. In the context of a method, a location corresponding with a reduced visibility event warning may be identified. Information regarding visibility at one or more stationary positions based upon the location of the reduced visibility event warning may be received from one or more remote devices (e.g., sensing apparatuses). The method may determine a reduced visibility event warning confidence for the location corresponding with a reduced visibility event warning based upon the information regarding visibility. The method may cause the reduced visibility event warning to be published in an instance in which the reduced visibility event warning confidence satisfies a confidence threshold.
