摘要： Techniques described herein relate to lane handling, for instance to enable vehicles to perform turns without colliding into oncoming vehicles and/or bicycles in other lanes. System(s) associated with a vehicle can access sensor data and/or map data associated with an environment within which the vehicle is positioned in a first lane. The system(s) can determine that the vehicle is to perform a turn and a start of a second lane associated with the turn or a merging zone associated with the second lane. The system(s) can determine a location of the vehicle relative to the start of the second lane or the merging zone associated with the second lane and, based partly on the location, can cause the vehicle to merge into the second lane prior to performing the turn.

摘要： A method for detecting a traffic law violation due to the allowable distance between a following vehicle and a guide vehicle being undershot, the following vehicle traveling behind the guide vehicle. At least the respective speed of the following vehicle is identified and the guide vehicle in a detection region in the surroundings of a sensor which supplies speed measurement values. A reference distance is detected and/or ascertained between the following vehicle and the guide vehicle at a reference measurement point. At least one following distance is determined between the following vehicle and the guide vehicle in the detection region using the identified speeds of the following vehicle and the guide vehicle and/or the detected reference distance. A traffic law violation is detected if the following distance in the detection region continuously falls short of a distance threshold.

摘要： A method for detecting the presence of an emergency vehicle includes receiving a plurality of image frames over a period of time, determining an EV colour component for each image frame based on the ratio of a first colour relative to the total colour in each pixel and assigning to a pixel a first value if the EV colour component exceeds a predefined threshold value and a second value if the EV colour component does not, and determining for an EV colour value for the first colour based on the sum of all of the first values for each image frame. The method also includes generating a time domain representation, converting the time domain representation for the plurality of image frames to a frequency spectrum, and determining if any flashing light sources of the first colour associated with one or more types of emergency vehicles is present.

摘要： A method for tracking and characterizing a plurality of vehicles simultaneously in a traffic control environment, comprising: providing a 3D optical emitter; providing a 3D optical receiver with a wide and deep field of view; driving the 3D optical emitter into emitting short light pulses; receiving a reflection/backscatter of the emitted light, thereby acquiring an individual digital full-waveform LIDAR trace for each detection channel of the 3D optical receiver; using the individual digital full-waveform LIDAR trace and the emitted light waveform, detecting a presence of a plurality of vehicles, a position of at least part of each vehicle and a time at which the position is detected; assigning a unique identifier to each vehicle; repeating the steps of driving, receiving, acquiring and detecting, at a predetermined frequency; tracking and recording an updated position of each vehicle and an updated time at which the updated position is detected.

摘要： A server device includes a receiver and a processor. The receiver is configured to receive lane state/vehicle position information of an idle lane via a first communication network. The receiver is configured to receive own-vehicle position information of a vehicle via a second communication network. The receiver is configured to receive a travel request for the idle lane from the vehicle via a third communication network. In response to the travel request, the processor determines whether traveling in the idle lane is available to the vehicle, based on the own-vehicle position information of the vehicle and the lane state/vehicle position information of the idle lane.

摘要： A system, computer readable medium, and a method for parking management are provided. The method receives, via communication circuitry, an input from an electronic device. The input includes at least destination information of a user of a vehicle. The method identifies a parking space for the vehicle based on the input and generates navigational directions to the identified parking space. Further, the method provides the navigational directions to at least one output device.

摘要： A detection device and an indoor navigation system are provided. The detection device includes two detection modules each including a sound receiver for receiving sound from a peripheral object and a signal converting circuit that is electrically coupled to the sound receiver and that is configured to convert input signal from the sound receiver into a target spectrogram. The two spectrograms from the signal converting circuits have a time/phase difference, and at least one wireless earphone includes a storage unit and a judging circuit that is electrically coupled to the storage unit and the two signal converting circuits. The judging circuit is configured to compare any target spectrogram with basic spectrograms of the storage unit so as to determine which kind of objects the peripheral object is, and is configured to obtain an instant position of the peripheral object by the time/phase difference.

摘要： A vehicle movement predicting device includes an inter-vehicle communication part that obtains vehicle information from communicable vehicles around an own vehicle, a vehicle position measuring part that measures a position of a preceding vehicle of the own vehicle, a communicable vehicle selecting part that decides a past position closest to the position of the preceding vehicle on the basis of the vehicle information, calculates a closest distance between the past position and the position of the preceding vehicle and a direction difference between the preceding vehicle and the communicable vehicle, and thereby selects one from among the communicable vehicles each of which the closest distance and the direction difference are respectively predetermined values or less, as a front vehicle of the preceding vehicle, and a vehicle movement predicting part that predicts a future movement of the preceding vehicle on the basis of the position of the selected communicable vehicle.
