Abstract: A road condition generation method is provided for a computing device. The method includes obtaining current driving state information; based on the current driving state information, generating road condition state information according to transition information between road condition states extracted from historical road condition data and a correspondence between the road condition states and road section traffic capacity information; and outputting the road condition state information.

Abstract: A method is provided for obtaining road-condition information by a terminal. The method includes: obtaining first real-time driving data transmitted by a first vehicle currently passing a target road segment, and obtaining first driving characteristic-information of the target road segment based on the first real-time driving data; obtaining second real-time driving data transmitted by a second vehicle currently passing a topology road segment, and obtaining second driving characteristic-information of the target road segment based on the second real-time driving data, the topology road segment being an adjacent road segment within a target range of the target road segment; and obtaining road-condition information of the target road segment using a trained road-condition prediction model and based on the first driving characteristic-information and the second driving characteristic-information, and outputting the road-condition information.

Abstract: Disclosed are a method for a reader to provide a service, a reader and a computer storage medium. The method includes: obtaining and displaying, by a reader, at least one piece of plugin information, the plugin information including at least a plugin name; determining plugin information selected by a user from the at least one piece of plugin information, and downloading a corresponding plugin file according to the selected plugin information; and installing a plugin according to the downloaded plugin file, and invoking the plugin installed to provide a corresponding service. By enabling the reader to download a corresponding plug-in file according to plug-in information selected by a user, i.e., downloading the corresponding plug-in file according to the user's needs, the size of a reader installation package in the present disclosure can be controlled effectively, thereby saving traffic.
