摘要： Reckless behavior of drivers like, speeding, sudden acceleration and swerving through lanes can cause fatality and financial loss. Conventional methods mainly focus on driving style classification. The conventional methods mainly focus on driver classification and are not able to provide trip classification of a driver. Hence there is a challenge in trip classification of the driver based on acceleration data. The present disclosure for trip classification addresses the problem of end to end trip classification based on the acceleration data. Here, a journey is segmented into a plurality of sub-journey segments and each sub-journey segment is associated with a plurality of driving events. An event score is calculated for each sub-journey and a normalization is performed on the event score. Further, the journey is classified into at least one of good, average or bad based on the normalized data by utilizing a fuzzy based classification.

摘要： One or more devices may obtain traffic data, such as video from intersection cameras, point cloud data from Light Detection and Ranging (or “LiDAR”) sensors, and so on. Metrics may be calculated from the traffic data. For each frame, the metrics may be analyzed to detect whether a near miss/collision occurs between each object in the frame (such as motorized or non-motorized vehicles, pedestrians, and so on) and each of the other objects in the frame. These metrics may be analyzed to evaluate whether or not a group of conditions are met. If the group of conditions are met, a near miss/collision may be detected. This may be recorded in the metrics for the objects involved. In some implementations, one or more indicators may be added to the traffic data and/or to one or more visualizations generated using the metrics, the traffic data, the structured data, and so on.

摘要： A communication system includes a central cloud server that detects the presence of an active sync path at each of a first edge device and a second edge device, where the first edge device is arranged at a first location at a vehicle and the second edge device is arranged at a second location of the vehicle. The central cloud server further determines a dominant edge device and a non-dominant edge device from the first edge device and the second edge device. The central cloud server further elects the determined dominant edge device from the first edge device and the second edge device to service one or more user equipment (UEs) in the vehicle, which improves performance in terms of data throughput and signal-to-noise ratio (SNR) of one or more UEs present in the vehicle by effectively controlling cooperation between two edge devices arranged in the vehicle.

摘要： A vehicle-mounted device includes a data collecting device that collects sensor data from a vehicle sensor, a data transmitting device that transmits the sensor data to a server, a data receiving device that receives data about an outside-vehicle status, and an inside-vehicle/outside-vehicle cooperation device that, in response to receipt of the data about the outside-vehicle status, cooperates with a device outside the vehicle and controls an operation inside the vehicle. The server includes a map creating device that maintains a traffic status overview map on the basis of received sensor data, a vehicle selecting device that selects a vehicle capable of transmitting optimum sensor data for maintaining the traffic status overview map in view of a line status among vehicle-mounted devices present within a specific area, and a transmission permission/prohibition signal transmitting device that transmits an instruction of permitting transmission of sensor data to the vehicle.

摘要： A method for predicting a remaining time of a signal phase includes capturing traffic data and a signal phase specification distinguishing different signal phases of a traffic signal generator. The traffic data is fed as input data to an artificial neural network including first and second sub-networks and a combination network for combining output data of the two sub-networks. The artificial neural network is trained to reproduce a time still remaining until a phase change of the traffic signal generator based on the traffic data. Outputting of the output data of the first and second sub-networks is controlled in a manner complementary to one another according to the signal phase specification. Lastly, the output data of the combination network or the prediction data derived therefrom are transmitted to a transport device or to a road user as a prediction of the time remaining for influencing traffic.
