S200 obtains initiating station, terminus and maximum number of transfer and pop down.That is, obtain to import the maximum number of transfer of initiating station, terminus and permission by the user; And with the maximum number of transfer parameter pop down of described initiating station, terminus and permission;
S201 searches the scheme by bus that all satisfy condition from current website.Described current website is meant current initiating station, promptly as the current website of initiating station, when first execution during to this step, described current website is the initiating station among the step S200, when being carries out to this step from following step S209, then described current website is the current website of determining through step S209;
S202 judges whether current initiating station is the terminus, if, then carry out S210, otherwise execution in step S203;
S203 judges whether still can change to, if, execution in step S204 then, otherwise execution in step S211.Judge whether still can change to by judging whether current number of transfer reaches the set maximum number of transfer of step S200 and realize; Because, every transfer number of transfer that once all will add up, thereby this determining step is set to prevent to surpass maximum number of transfer;
S204 gets a circuit from the public transport data of current website, and obtains next website on this circuit.For example: current initiating station is B234, and the circuit that can obtain comprising current website from the public transport data is L1, L2, L3, L4, L5, chooses a circuit this moment from L1～L5, and obtain next website of this circuit from local public transport data; Wherein, described next website can be next website of the current initiating station of neighbour, perhaps also can choose next website according to the step-length that sets in advance;
Whether S205 successfully obtains to have selected described next website of circuit, if then execution in step S206 seeks next circuit or next website otherwise re-execute step S204 among the determining step S204;
S206, selected circuit and website process whether among the determining step S204, if, execution in step S207 then, otherwise execution in step S204.Promptly, whether took this circuit before judging through this website, for example the current circuit that is calculating is till this step: initiating station is taken advantage of L1, transfer to L4 at the B398 station, get off at the B230 station, selected L2 and next website B987 through step S204 this moment, because do not take advantage of circuit L2 in the transfer part of website B987 in the part that has calculated, thereby the identification of this step is process not, thereby execution in step S207; For above-mentioned example, the situation of process does not also comprise, takes L2, but does not change at website B987, perhaps, does not take L2, but changes at website B987; Therefore, the situation of regarding as process has only a kind of, promptly takes L2 and changes at website B987;
S207 judges whether transfer, if, execution in step S208 then, otherwise execution in step S209.Whether for judging on the same line road, if then there is not the transfer relation in the same line road, thereby this step is judged as and does not change to according to the selected circuit of step S204 and a last circuit for it; If not the same line road then have the transfer relation, thereby this step is judged as transfer.Whether this step purpose is number of transfer to be added up in order to determine in step S208;
S208 writes down this circuit, and the number of transfer that adds up.That is, after successfully obtaining the next stop, then write down the described circuit and the described next stop, and simultaneously will be number of transfer add 1 (because judging it is not the same line road) through step S207;
S209, with the website that obtains as current website, and all circuits that will pass through and website and current number of transfer parameter pop down.That is, with the next stop that obtained among the step S204 as new current website once more execution in step S201 continue to finish complete circuit and calculate, simultaneously each parameter pop down is preserved.After this step finishes, execution in step S201;
S210, the record result.That is, when current website is the terminus, represent that promptly transfer plan finishes as calculated, store whole transfer plan this moment; And, calculate the expense of the required cost of this scheme simultaneously; This step finishes back execution in step S213;
For example, the complete scheme that finally obtains is as follows:
Initiating station is taken advantage of L1, at B555 website transfer L11, at B666 website transfer L21, at B777 website transfer L31, finally reaches terminal; At this moment, just from local transit database, obtain every circuit charging way, calculate the expense expenditure according to this charging way.Such as, the charging way of L1 is 1 yuan of a flat fare, L11 also is 2 yuan of flat fares, L21 is segmentation valuation, L31 is 1 yuan of a flat fare, and calculate the user take the L21 circuit the expense in highway section of process be 2 yuan, this moment, the expense expenditure was 1+2+2+1=6 unit;
S211 searches all straightforward lines between current website and the terminus.The straightforward line that it should be noted that here to be said be not be from original initiating station (initiating station that is provided with the step S200) to the straightforward line the terminus, but from current website to the straightforward line the terminus.
For example, the initiating station that is provided with among the step S200 is B1234, terminus B4321, current website is B888, it comprises website B888 and terminus B4321 to suppose in the public transport data of current website a circuit L007 is arranged, and then thinks that so-called straightforward line is arranged this moment, otherwise does not have;
S212 writes down the result that all can go directly.That is the record resulting straightforward line information of previous step (comprising complete line information);
S213 ejects one group of parameter from stack.That is, the information that is pressed into before in the storehouse is ejected;
S214 judges whether the data eject are empty from storehouse, if, execution in step S216 then, otherwise execution in step S215.That is, when going out stack content when empty, then expression finishes all possible circuit traversal this moment, can process ends; If be not empty, then expression does not travel through and finishes, and then continues execution in step S215;
S215 is made as current website with the website that ejects.That is, the current website in the data that eject among the step S213 is traveled through so that re-execute step S201 as initiating station;
Change among another embodiment of querying method in the present invention, on the basis of embodiment shown in Figure 3, in step S204, directly get not circuit and next website thereof of process, thereby can omit the determining step among the step S206.
Change among another embodiment of querying method in the present invention, on the basis of embodiment shown in Figure 3, can omit step S203, travel through out the circuit that all can reach terminal like this from the inception point, and between step S214 and S216, increase filtration to the number of transfer of whole schemes of obtaining, give up the scheme that surpasses maximum number of transfer.
Need to prove, public transport data of the present invention be meant might public transport mode combination.For example, the combination in any between bus, electric car, bullet train, subway or the light rail.
Above disclosed is a kind of preferred embodiment of the present invention only, can not limit the present invention's interest field certainly with this, and therefore the equivalent variations of doing according to claim of the present invention still belongs to the scope that the present invention is contained.
