As shown in Figure 8, carry out in the embodiment of the invention in the specific implementation process of road condition query, submit the key word of user's input to, the road condition query interface of request road conditions issue, relevant road conditions result's flow process is obtained in inquiry, specifically may further comprise the steps:
801, obtain the key word of user's input; Described key word can be road name or POI title;
802, call the road condition query interface, submit key word to;
803, judge that whether this key word is Chinese character entirely, is then to continue, otherwise changes step 805 over to;
804, key word is carried out word segmentation processing, extract the name list of keyword query and its relevant road; Behind the completing steps 804, directly jump to step 807;
805, check that whether key word is phonetic entirely, is then to continue, otherwise changes step 812 over to;
806, carry out the inquiry of road name initial according to key word;
807, judge whether the road condition query interface returns road name, have then and continue, otherwise change step 813 over to;
808,, inquire about the traffic information of each bar road according to the road name tabulation of returning;
809, the content standard according to issue requires to organize;
810, return front end road condition query result;
811, front end is adjusted the road conditions text style and is shown, process finishes afterwards.
812, the key word of prompting input is undesirable, please re-enter, and process finishes.
813, there is not this road in prompting, please re-enter, and process finishes.
In the present embodiment, the realization flow that road conditions are reported is roughly similar to the road condition query flow process shown in Fig. 8, but the key word that gets access to when carrying out the road conditions report is city title or the zone name that the user imports; Therefore, the specific implementation process of reporting for road conditions repeats no more herein.
As shown in Figure 9, carry out submitting the starting point and the terminal point POI title key word of user's input in the specific implementation process of dynamic route planning the optimal path inquiry interface of request road conditions issue in the embodiment of the invention, the optimum traffic route information of point-to-point transmission is obtained in inquiry, specifically may further comprise the steps:
901, obtain the starting point key word and the endpoint keyword of user's input; Described starting point key word and endpoint keyword can be the POI titles;
902, call the POI query interface, submit described starting point key word and endpoint keyword to;
903, judge that whether the starting point key word is Chinese character entirely, is then to continue, otherwise changes step 912 over to;
904, judge that whether endpoint keyword is Chinese character entirely, is then to continue, otherwise changes step 913 over to;
905, obtain the POI title according to key word;
906, judge whether the starting point POI and the terminal point POI return results of POI query interface feedback, be then to continue, otherwise change step 911 over to;
907, forward end return to origin and terminal point name list and demonstration;
908, starting point and the terminal point POI title of selecting according to the user called the optimal path inquiry interface, obtains the optimal path information of point-to-point transmission;
909, having judged whether return results, is then to continue, otherwise changes step 914 over to;
910, front end is adjusted the route text style and is shown, process finishes;
911, starting point and terminal point POI are not found in prompting, and process finishes;
912, the starting point key word of prompting input is undesirable, please re-enter, and process finishes;
913, the endpoint keyword of prompting input is undesirable, please re-enter, and process finishes;
914, optimal route is not found in prompting, and process finishes.
In embodiments of the present invention, can directly give the user, also can directly be issued on the user terminal (such as mobile phone) by the mode of note or multimedia message by the PC interface display by the Query Result that service inquiry gets access to.
As shown in figure 10, in the specific implementation flow process that the short multimedia message that provides in the embodiment of the invention issues,, organize generation according to the content standard requirement of note or multimedia message, and issue user mobile phone by note/MMS gateway with Query Result; Wherein, described Query Result comprises: road name, direction, the degree of blocking up, and/or, traffic events spot, traffic events type and event content.Idiographic flow can may further comprise the steps:
1001, obtain the type that issues of user's selection;
1002, judge whether the described type that issues is note, is then to continue, otherwise changes step 1004 over to, carries out multimedia message and issues processing;
1003, require tissue to issue content according to short message content, change step 1008 afterwards over to;
1004, call multimedia message picture and generate interface, submit type, size, indication range and the rank of picture to;
1005, generate multimedia message picture and returning;
1006, require to organize picture and word content according to MMS content;
1007, encode according to the multimedia message standard, change step 1009 over to;
1008, call note and issue interface routine, finish note and issue, process finishes;
1009, call multimedia message and issue interface routine, finish multimedia message and issue, process finishes.
In said process, mentioned short message content can comprise inquiry or report the magnitude of traffic flow description or the traffic events description of road that the particular content form shows with Web.
, can also comprise inquiry or report the magnitude of traffic flow of road or the picture demonstration of traffic events except comprising the text description to the magnitude of traffic flow or traffic time as for MMS content, the pattern of describing of described picture and pattern and Web show basic identical; But, road grade quantity during picture shows and the quantity of POI are lacked than Web, so just can not influence the display effect of picture on terminals such as mobile phone.In addition, the size of picture should comprise polytypes such as 176*220,240*320, to support the demonstration of different mobile phones.
The road conditions dissemination method that the embodiment of the invention provides based on Web, the map shows of transport information interconnected with the mobile network with text query and internet fully combine, can provide effective decision support for the problem under the multiple trip scene of the public, improve the public's the line efficiency that goes out, the management that also can be simultaneously urban transportation provides reference, has positive meaning for alleviating the urban traffic blocking situation.
The above; only be the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
