receiving, by the server, the request from the client device, obtaining the traffic information corresponding to the candidate route from the traffic information of the road network, and sending the traffic information corresponding to the candidate route to the client device;
or initiatively sending, by the server, the traffic information of the road network to the client device;
or initiatively sending, by the server, the traffic information corresponding to the candidate route to the client device after the client device selects the candidate route; and
presenting, by the client device, the traffic information provided by the server;
wherein the selecting, by the client device, the candidate route, and sending to the server the request for the traffic information corresponding to the candidate route;
receiving, by the server, the request from the client device, obtaining the traffic information corresponding to the candidate route from the traffic information of the road network, and sending the traffic information corresponding to the candidate route to the client device comprises;
determining, by the client device, a driving start point, a driving dwell point and a driving end point, and sending the driving start point, the driving dwell point, the driving end point and a request for the traffic information to the server;
calculating, by the server, the set of candidate routes according to the driving start point, the driving dwell point and the driving end point, and sending the set of candidate routes and traffic information corresponding to each candidate route in the set of candidate routes to the client device; and
selecting, by the client device, the candidate route from the set of candidate routes according to the traffic information corresponding to each candidate route in the set of candidate routes;
wherein the client device has at least two different states of operation, (i) online state and (ii) offline state, sending the traffic information corresponding to the candidate route to the client device comprises;
determining, by the server, a state of the client device as one of the online state and offline state;
selecting, by the server, an information channel automatically according to the determined state of the client device; and
sending, by the server, the traffic information corresponding to the candidate route to the client device through the selected information channel.

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.
