Abstract: A method and apparatus for adjusting channelization of a traffic intersection are proposed. The specific implementation of the method is: obtaining a first traffic characteristic of vehicles at each of a plurality of target positions in a process of vehicles in a target traveling direction traveling through the traffic intersection from upstream to downstream in a preset first time period; generating first traffic change information of the traffic intersection based on the first traffic characteristic at each of the plurality of target positions; and in response to that the first traffic change information satisfies a preset first change distribution, generating channelization adjustment information for non-motorized vehicle lanes of the traffic intersection.

Abstract: The present disclosure provides an information processing method, system, device and computer storage medium. The method comprises obtaining obstacle information acquired by an ultrasonic radar and a LiDAR respectively; fusing the obstacle information acquired by the LiDAR with the obstacle information acquired by the ultrasonic radar. The present disclosure avoids the problem that whether there is an obstacle laterally in front of or directly in front of the vehicle cannot be judged only according to the obstacle information returned by the ultrasonic radar, so that the driverless vehicle will stop automatically to avoid collision and its normal drive is affected, improves the obstacle recognition precision and ensures safe and stable drive of the driverless vehicle.

Abstract: The present disclosure provides a data acquisition method, apparatus, device and computer readable storage medium. According to the embodiments of the present disclosure, determination is made as to whether a preset stable driving condition is met based on acquired driving scene data of the driving scene where the vehicle is currently located, and acquired driving behavior data; if the preset stable driving condition is met, the driving scene data and the driving behavior data are acquired at a frequency lower than a preset sampling frequency. As a result, it is possible to reduce data redundancy in similar scenes and similar diving modes, reduce the amount of data, reduce occupation of the storage resources and transmission resources and facilitate subsequent analysis, and it is possible to implement the dynamic acquisition of driving scene data and driving behavior data by scenes and modes.
