Abstract: A method includes obtaining a roadside sensing result that indicates a first group of location points that are of a traffic participant sensed by a first roadside device in a preset time period, and a multi-source fusion sensing result that indicates a second group of location points obtained by fusing a plurality of groups of location points that are of the traffic participant and that are obtained by a plurality of sensing devices in the preset time period; matching the roadside sensing result with the multi-source fusion sensing result; and generating first sensing capability information of the first roadside device based on the matching result.

Abstract: A map data processing method includes obtaining risk event information that includes time information and location information, where the time information indicates a predicted time range of a risk event, and the location information indicates a predicted region range of the risk event. Prediction of a risk event that may occur in a specific geographical region range can be provided. In addition, a lowest-risk path can be further planned based on the risk event information.

Abstract: A high-definition map update method includes obtaining n-dimensional feature information of a dynamic event in n dimensions, where the n dimensions are n factors that affect representation of the dynamic event in a high-definition map, the dynamic event is an event that causes dynamic information in the high-definition map to change, and n is an integer greater than one, and determining, based on the feature information, a representation manner of the dynamic event in the high-definition map, where the representation manner includes at least one of an extended attribute representation manner or a dynamic layer representation manner.

Abstract: In a method of generating an event map, a processing device obtains first information that indicates that there is an association relationship between a first event and a second event. The first information comprises association type information that indicates a type of the association relationship, and the first and second events are events in a map. The processing device then stores the first information as data of the map.
