Path induction information demand acquisition module, traffic information demand acquisition module and traffic value-added information demand acquisition module.
Path induction information demand acquisition module is the core of this device, is used to obtain the information such as origin and destination, path, mode of transportation and constraint condition of user's trip, the preference information etc. of for example going on a journey.Further: the origin and destination, path comprise from, starting point node, terminal point city and peripheral node composition again; Mode of transportation is divided into self driving and transit trip two classes; The trip preference is divided into public transport preference and self driving preference.
Public transport comprises: bus, subway, light rail, railway, aviation, long-distance passenger transportation;
Self driving is the conventional self driving of understanding; The self driving preference is for example: distance is the shortest, expense is minimum, advanced road;
The trip preference refers to constraint condition when carrying out path planning, for example: change to minimum, distance is the shortest, expense is minimum, the most comfortable etc.;
The traffic information deriving means obtains the traffic information type of the needs of user's submission: some traffic information or circuit condition information, wherein: the some traffic information refers to the road conditions of a certain node, as Xizhimen Qiao Chu road conditions, circuit condition information refers to the road conditions in stretch footpath, as the road conditions of Xizhimen bridge to Fuchengmen.
Whether what traffic value-added information demand acquisition module judged that the user submits to also needs other value-added services, mainly comprises: parking lot information, fuel station information, weather information and ticket information etc.
As shown in Figure 3, described the main flow process that traffic-information service demand acquisition module 102 obtains information: path induction information demand acquisition module at first obtains path induction information demand and specifically comprises origin and destination information, mode of transportation and trip preference relevant information; Then, traffic information demand acquisition module obtains the traffic information demand; Last traffic value-added information demand acquisition module obtains the traffic value-added information, comprises refuelling station's demand information, parking lot demand information, weather demand information and ticket information.Traffic-information service demand acquisition module according to this order with the user submit to demand be converted to the Web list and export to traffic-information service demand decomposer 103.
Still referring to shown in Figure 2, traffic-information service demand decomposer 103 mainly comprises with lower module:
Web form information modular converter, demand decomposing module and XML document generation module.
Wherein, Web form information modular converter is used for the original demands information of user's submission of Web list form is saved in original demands information array broomrape, comprises original demands information type and the original demands value of information, i.e. associative key.The original demands information type is a kind of demand that defines in the XML demand identification template, keyword input frame or choice box according to correspondence are determined, for example in the start node of path query and peripheral node input frame, imported corresponding keyword, shown that then the user has the demand of path query;
All leaf nodes in the demand decomposing module traversal XML demand identification template, in original demands information array row, search for the original demands information that the pairing user of each leaf node submits to simultaneously, and obtain more demand information (for example province, city numbering etc. under node serial number, the city by City table in the retrieval ACCESS database and Point table, in order to each demand further is mapped as a plurality of executable transport information Web service that can not be split), thus the demand disintegration finished.
The XML document generation module generate one with the corresponding multiway tree of demand identification template, and will before the decomposition result assignment that obtain in this multiway tree, be parameter call XML document generating apparatus with this multiway tree at last, generate the demand information XML document of user's submission.Need to prove, in XML demand identification template, a transport information demand may be by one or more leaf nodes and superior node definition thereof, the original demands information that the user of leaf node correspondence submits to, the superior node attribute information of leaf node has defined the effect in the demand in the leaf node.Generating a multiway tree corresponding with demand identification template is exactly identification template according to demand, with each keyword of user input and the relevant information assignment obtained each leaf node in the XML demand identification template, when for example start node is Beijing Guan Yuanqiao, determine that according to the input frame of official garden bridge the demand type is a path query, and official garden bridge is a start node, then the start node assignment with this query demand in the XML demand identification template of correspondence is an official garden bridge, the upper level father node attribute information of official garden bridge shows it is node, and more the attribute information of upper level grandfather node shows start node for the path query demand.Attribute information is the name of node, and for example the father node of pointName node is that point, grandfather's node are Origin.
PointName: Guan Yuanqiao;
Father node: point;
Grandfather's node: Origin;
Great grandfather's node is root node: routeRequest;
According to the attribute information of father node, grandfather's node and great grandfather's node, can determine that " Guan Yuanqiao " this key word information is starting point node name in the path query service.
If also have the Weather information inquiry, then need urban information assignment with the urban information of trip start node and terminal node to the leaf node of weather query demand.
Finally, be the various traffic-information service demands that the user needs in XML demand identification template by the demand of the leaf node correspondence of assignment, all the other are not the traffic-information service demands that the user needs by the demand of the leaf node correspondence of assignment.
As shown in Figure 4, described the main flow process of traffic-information service demand decomposing module: at first the original demands information that the user of Web list form is submitted to is saved in the original demands information array broomrape, and preservation information comprises the original demands information type and the original demands value of information.Travel through all leaf nodes in " XML demand identification template " then, in original demands information array row, search for the original demands information that the pairing user of each leaf node submits to simultaneously, and obtain more demand information (for example province, city numbering etc. under node serial number, the city), thereby finish the demand disintegration by City table in the retrieval ACCESS database and Point table.Use the array row realize one with " demand identification template " corresponding multiway tree, and with the decomposition result assignment that obtain before in this multiway tree.Last traffic-information service demand decomposing module can be a parameter call XML document generation module with this multiway tree, generates the demand information XML document of user's submission and sends to traffic-information service demand mapping device.
Still referring to as shown in Figure 2, traffic-information service demand mapping device mainly comprises with lower module: information requirement and Web service mapping block and XML document generation module.
The demand information XML document that information requirement and Web service mapping block traversal user submit to, determine the unit service of its pairing XML transport services in describing according to the attribute information of the father node at the value of each leaf node and its place, grandfather's node, classification in describing according to the XML transport services again is mapped to a plurality of transport information Web services of carrying out with demand.
The XML document generation module generate one with the corresponding multiway tree of XML transport services description, and will go up the resultant Web service assignment of a module in this multiway tree.Be parameter call XML document generating apparatus with this multiway tree at last, generate transport services demand XML document.Thereby set up and " XML transport services description " corresponding transport services demand inventory.
The XML document generating apparatus travels through resulting multiway tree with level traversal method, use in the .NET platform System.Xml class simultaneously and generate and the corresponding XML document of above-mentioned multiway tree, for traffic-information service demand decomposer and traffic-information service demand mapping device used.
As shown in Figure 5, the main flow process of traffic-information service demand mapping block has been described: at first travel through the demand information XML document that the user submits to, determine unit's service in its pairing " XML transport services description " according to the attribute information of the value of each leaf node and its father node of place, grandfather's node, according to the classification in " XML transport services description ", demand is mapped to the needed Web service that the user submits to again.Use one of array column-generation and " XML transport services description " corresponding multiway tree, and be parameter call XML document generation module, generation XML transport information Web service document with this multiway tree.
For flow process and the result that this system of explanation utilization more intuitively carries out the identification of traffic-information service demand, be example with one section traffic-information service request down from official garden, Beijing bridge to the outbeach, Shanghai City, the implementation process of demand identification is described.Particular content is as follows:
The first step: obtain the traffic-information service original demands that the user submits to.
The webpage that the user provides by comprehensive traffic information service website, in pull-down menu, select real needs to comprise:
From: Beijing;
Starting point node: Guan Yuanqiao;
Terminal point city: Shanghai City;
Peripheral node: outbeach;
Mode of transportation: public transport;
The public transport preference: expense is minimum;
Traffic information demand: do not have;
Value-added service demand: Weather information, ticket information.
After the demand information setting is finished, the user confirms and submits to and ask, traffic-information service demand deriving means obtains the original traffic trip demand information of user's submission and exports to traffic-information service demand decomposing module with the form of web list, triggers traffic-information service demand decomposing module and carries out the demand decomposition.
Second step: decompose the traffic-information service demand.
At first Web form information modular converter generates the Web form information with previous step and dumps among the array row needArrayList.
Traffic-information service demand decomposing module traversal " XML demand identification template " atisMessage searches for the object among the pairing needArrayList of each leaf node then.Leaf node for example: type is the object of originPointName among the pairing needArrayList of atisMessage-routeRequest-routeOutLine-origin-point-pintN ame, and its value is an official garden bridge.This module is connected to the relevant information of Access data base querying node " Guan Yuanqiao " afterwards.
Generate multiway tree needTree according to " XML demand identification template " atisMessage at last, the call XML document creation module generates " demand information XML document ".
The 3rd step: the mapping of transport information demand and Web service.
At first traffic-information service demand mapping block travels through the transport services requirement documents, determine transport information Web service in its pairing " XML transport services description " according to the attribute information of the father node at the value of each leaf node and its place, grandfather's node, according to the classification in " XML transport services description ", demand is mapped to the needed Web service that the user submits to again.
Generate then one with " XML transport services description " corresponding multiway tree serviceTree, be parameter call XML document generation module with this multiway tree at last, generate transport services demand XML document, as shown in Figure 6.
So far just finish all processes of demand identification, and generated last transport services demand XML document.
