摘要： A method for determining a cooperative maneuver for an ego vehicle is provided. The method includes determining a maneuver of the ego vehicle based on traffic information in a target lane, selecting one or more cooperative vehicles to be involved in the maneuver, determining whether the maneuver of the ego vehicle and actions of the one or more cooperative vehicles trigger congestion in the target lane based on simulation of the maneuver and the actions, instructing the ego vehicle to perform the maneuver in response to determining that the maneuver of the ego vehicle and actions of the one or more cooperative vehicles do not trigger congestion, and adjusting a number of cooperative vehicles to be involved in the maneuver in response to determining that the maneuver of the ego vehicle and actions of the one or more cooperative vehicles trigger congestion.

摘要： A method for the automatic merging of a vehicle from a slip road into a lane of traffic involves determining a primary merging position in advance at which the vehicle is to undertake a lane change from the slip road to the lane of traffic. If the lane change at the primary merging position or as close as possible to it does not lead to road users in the lane of traffic being obstructed, the vehicle is controlled in such a way that the lane change is carried out at the primary merging position. Otherwise, the lane change is carried out at a secondary merging position which is determined depending on detected clearances between road users in the lane of traffic.

摘要： An autonomous vehicle is equipped with a beacon, preferably including a transmitter and receiver, or a transceiver, for bi-directional communication, which is programmed to interact with other beacons for the exchange of contextual travel information to assist in autonomous operation of the vehicle. Beacons may be stationary and positioned along a roadway such that a signal transmitted by such a stationary beacon can be received by a passing beacon-equipped vehicle, the operation of which can be adjusted depending on instructions received from the stationary beacon. The vehicle can also transmit information to the stationary beacon, which information can be used to assess traffic conditions to thereafter adjust information and alerts sent to other beacon-equipped vehicles. Beacons located within multiple vehicles may also interact to share information that may be used by individual vehicles to adjust or maintain the autonomous operation of the vehicle.

摘要： Embodiments describe new mechanisms for signalized intersection control. Embodiments expand inputs beyond traditional traffic control methods to include awareness of agency policies for signalized control, industry standardized calculations for traffic control parameters, geometric awareness of the roadway and/or intersection, and/or input of vehicle trajectory data relative to this intersection geometry. In certain embodiments, these new inputs facilitate a real-time, future-state trajectory modeling of the phase timing and sequencing options for signalized intersection control. Phase selection and timing can be improved or otherwise optimized based upon modeling the signal's future state impact on arriving vehicle trajectories. This improvement or optimization can be performed to reduce or minimize the cost basis of a user definable objective function.

摘要： A system for adaptively controlling traffic control devices having a traffic signal system, a computing network, a communication system, and a mobile device. The traffic signal system is configured to be in communication with the computing network through the communication system. The mobile device is also configured to be in communication with the computing network through the communication system. Then the computing network adaptively controls the traffic signal system using a location of the mobile device.

摘要： Systems and methods are provided for interpreting traffic information for a vehicle. In one embodiment, a method includes: collecting, by a processor, sensor data from at least one first sensor device of the vehicle; determining, by the processor, at least one relevant object within the sensor data based on a window defined by a plurality of ranges and associated elevations, wherein the plurality of ranges and associated elevations are defined relative to the at least one first sensor device; determining, by the processor, a confidence score of the at least one relevant object based on an identification of at least one pattern of activity of other objects associated with an intersection; determining, by the processor, a subset of sensor data from at least one second sensor of the vehicle based on the confidence score of the relevant object; and generating, by the processor, traffic device data for use in controlling the vehicle based on an evaluation of the subset of sensor data.

摘要： The technology described herein provides Automated Driving System (ADS) methods and systems for coordinating and/or fusing intelligence and functions between Connected Automated Vehicles (CAV) and ADS infrastructure to provide target levels of automated driving. The technology provides systems and methods for function allocation comprising sensing allocation, prediction and decision-making allocation, and control allocation. The ADS operates across various intelligence levels, identified during vehicle operation. The function allocation system dynamically allocates essential functions based on the intelligence levels of both vehicles and infrastructures, ensuring that ADS achieves a system intelligence that surpasses that of individual components. This methodical function distribution enables ADS to manage both vehicles and infrastructures in a manner that enhances vehicular operations and control. The system further integrates a fusion system to support various ADS functions through data integration from multiple sources, which optimizes the driving tasks performed by CAVs.

摘要： The present disclosure provides a method for traffic scheduling at an intersection in a smart city and an Internet of Things system. The method includes: for the intersection in a preset area, determining whether traffic congestion is likely to occur at the intersection during a next time period based on a comparison result between the number of the first vehicles and the number of second vehicles; in response to determining that the traffic congestion is likely to occur at the intersection during the next time period, determining whether a traffic scheduling strategy is needed to be switched based on traffic data information of the intersection during the next time period; and in response to determining that the traffic scheduling strategy is needed to be switched, switching a first traffic scheduling strategy to a second traffic scheduling strategy.
