Abstract: A method can be used to provide smart notifications to avoid collisions while the vehicle maneuvers in a tight structural environment, such as a home garage or an underground parking lot. The method includes receiving historical vehicle-trajectory data. The historical vehicle-trajectory data includes the location and the heading of the vehicle for each of the plurality of historical trajectories along the structure. The method further includes clustering the plurality of historical trajectories of the vehicle along the structure by types of maneuvers to generate a plurality of trajectory clusters. The method also includes creating a probability distribution bitmap using the plurality of trajectory clusters and creating a topographic map based on the probability distribution bitmap.

Abstract: A method for generating garage parking notifications includes receiving current parked-vehicle data indicating that a vehicle has been parked inside a garage. The current parked-vehicle data includes the current location of the vehicle parked inside the garage. The method further includes determining whether the current location of the vehicle inside the garage is within a warning zone. The warning zone is an area inside the garage where the vehicle has not been frequently parked. The warning zone area is determined using historical parked-vehicle data. The method further includes generating a notification to warn an operator of the vehicle that the vehicle should be moved in response to determining that the current location of the vehicle inside the garage is within the warning zone.

Abstract: A method of utilizing basic safety messages (BSMs) to provide insight of traffic situations to a vehicle-to-everything (V2X) enabled vehicle includes one or more of the following: transmitting BSMs from on-road vehicles; forwarding V2X messages including BSMs to a multi-access edge computing (MEC) server; extracting data samples from the V2X messages including BSMs; generating statistical results from the extracted data samples; and visualizing the statistical results for a driver of the vehicle.

Abstract: Methods and systems are provided for vehicle speed planning based on timing of traffic lights. In an exemplary embodiment, a disclosed system includes one or more sensors of a vehicle; a transceiver; and a processor. The one or more sensors are configured to obtain vehicle sensor data pertaining to operation of the vehicle. The transceiver is configured to obtain traffic light data with respect to a plurality of traffic lights along a path or roadway on which the vehicle is travelling. The processor is coupled to the one or more sensors and to the transceiver, and is configured to at least facilitate: determining a desired control of movement of the vehicle based on the vehicle sensor data, the traffic light data, and one or more optimization criteria pertaining to the vehicle; and taking a vehicle action based on the desired control of movement of the vehicle.
