Abstract: The disclosure includes embodiments for decreasing false positive notifications of abnormal driving behavior to a driver of an ego vehicle. The method includes detecting, based one or more first sensor measurements recorded by a sensor set of an ego vehicle, a presence of an adverse driving condition caused by a remote vehicle. The method includes determining a first severity of the adverse driving condition based on the one or more first sensor measurements. The method includes determining a second severity of the adverse driving condition based at least in part on one or more second sensor measurements. The method includes providing, by the ego vehicle, a notification of the adverse driving condition caused by the remote vehicle responsive to the second severity increasing relative to the first severity so that an increasing severity trend is present wherein the notification is not provided if the increasing severity trend is not present.

Abstract: One embodiment of a system for analyzing the in-lane driving behavior of an external road agent generates a sequence of sparse 3D point clouds based on a sequence of depth maps corresponding to a sequence of images of a scene. The system performs flow clustering based on the sequence of depth maps and a sequence of flow maps to identify points across the sequence of sparse 3D point clouds that belong to a detected road agent. The system generates a dense 3D point cloud by combining at least some of those identified points. The system detects one or more lane markings and projects them into the dense 3D point cloud to generate an annotated 3D point cloud. The system analyzes the in-lane driving behavior of the detected road agent based, at least in part, on the annotated 3D point cloud.

Abstract: A system includes a processor and a memory in communication with the processor. The memory has instructions that, when executed by the processor, cause the processor to count, based on sensor data received from vehicles located in a parking lot, the number of non-parked vehicles located in the parking lot within a time period. The instructions further cause the processor to determine an occupancy status of the parking lot based on the number of non-parked vehicles located in the parking lot.
