Abstract

A method for prompting traffic condition information, comprising: a server obtaining traffic condition information about a road network (101); a client determining a candidate driving route and sending to the server a traffic condition information request aiming at the candidate driving route, and the server receiving the traffic condition information request, extracting traffic condition information about the candidate driving route from the traffic condition information about the road network, and sending to the client the traffic condition information about the candidate driving route; alternatively, the server actively sending to the client the traffic condition information about the road network (102); and the client displaying the traffic condition information provided by the server (103). The method can prompt traffic condition information in time, thereby improving the reminding efficiency; it can also be applied in various terminal devices, and can be used across platform terminals, thereby having a wide scope of application.
