Abstract: The present application discloses a map data updating method, an apparatus, a device and a readable storage medium. The specific implementation solution is: after receiving road information reported by an electronic device, a server obtains multiple sequences according to the road information, and each road information belonging to the same sequence has the same type and location. After that, the server inputs each road information contained in the sequences to a pre-trained neural network model, so that the neural network model outputs a recognition result according to the sequences. The server updates map data according to the recognition result. With such solution, valid road information is recognized by combining context of each road information in the sequences and the neural network technology, and the map data is updated, which achieves the purpose of accurately updating the map data.

Abstract: The present application discloses a method and an apparatus for processing navigation data, a device and a storage medium, which relates to the fields of automatic driving and intelligent transportation, etc. The specific implementation solution is: in a process of vehicle driving, by obtaining real-time traffic status information of a local route within a distance ahead in real time, sending the real-time communication state information of the local route to a server, and optimizing and adjusting a recommended order of each candidate route by the server according to the real-time traffic status information of the local route, a current optimal navigation route can be determined by the vehicle terminal according to an adjusted recommended order of candidate routes, thereby can dynamically optimize and adjust a navigation route according to a real-time traffic status of the local route ahead, and provide a better navigation route for a vehicle.
