    摘要： A system for monitoring a traffic condition can include a processor and a memory. The memory can store a preliminary operations module, a calculations module, and a communications module. The preliminary operations module can include instructions that cause the processor to obtain information about the traffic condition of stopped or slow moving vehicles. The calculations module can include instructions that cause the processor to: (1) define a monitoring zone that encloses the traffic condition and (2) determine, based on data about velocities of vehicles in the monitoring zone, that an error of a prediction of a position of a vehicle, associated with the traffic condition, is less than a threshold. The communications module can include instructions that cause the processor to: (1) receive the data and (2) cause, in response to a determination that the error is less than the threshold, the information to be communicated to vehicles.

    摘要： Systems and methods described herein relate to customized machine-learning-based model simplification for connected vehicles. One embodiment executes a first training procedure for a machine-learning-based teacher model and performs the following repeatedly until convergence occurs: (1) distributing, to connected vehicles, a set of teacher-model parameters from the teacher model; (2) receiving, from each connected vehicle, a set of student-model parameters for a student model trained through a second training procedure employing first knowledge distillation to mimic the teacher model, wherein the student model is less complex than the teacher model; and (3) executing a third training procedure including second knowledge distillation in which a combined model from the sets of student-model parameters acts as a quasi-teacher model to update the teacher model. After convergence, a vehicular application, instantiated in a connected vehicle, controls operation of the connected vehicle based, at least in part, on the student model in the connected vehicle.

    摘要： A system for communicating a traffic condition to an upstream vehicle can include a processor, disposed on an ego vehicle, and a memory. The memory can store a determination module and a communications module. The determination module can include instructions that cause the processor to determine, by the ego vehicle in a first lane, an existence of the traffic condition that includes a difference, between an actual velocity of a vehicle in a second lane and an expected velocity, being greater than a threshold. The communications module can include instructions that cause the processor to: (1) cause, in response to the existence, a communications device of the ego vehicle to communicate, to the upstream vehicle, information about the traffic condition and (2) cause, in response to an absence of the existence, the communications device to refrain from communicating, to the upstream vehicle, the information about the traffic condition.

    摘要： A system for determining a lane change decision based on a downstream traffic state can include a processor, a communications device, and a memory. The processor can be disposed on an ego vehicle. The memory can store an acceleration gain module and a communications module. The acceleration gain module can include instructions that cause the processor to: (1) obtain, via the communications device and from a monitoring system, information about an end of stopped or slow moving downstream traffic in a lane and (2) calculate a result of an equation for the lane change decision. The equation can include information about virtual vehicles positioned near the end or a geographical location. The communications module can include instructions that cause the processor to cause a signal, with information based on the result, to be sent to a component of the ego vehicle for an action to be performed by the component.
