From n=1, increase progressively 1 successively to n=N, n, to travel through the GPS position information of all buses in queue T, with comparing of the GPS position information of the GPS position information of carrying out bus and the described starting station and terminus, specifically comprise following 301 to step 306:
Step 301, n is initialized as 1, enters step 302 afterwards.
Step 302, from queue T, obtain the n-th GPS position information of bus, enter step 303 afterwards.
Step 303:

Enter step 304 afterwards.
Step 304, judge Δ G
nwhether A is less than or equal to 200 meters:
If Δ G
na is less than or equal to 200 meters, then illustrate that bus n-th GPS location is in the A of the starting station, now, by " G
n" add in memory queue Q, represent that bus n-th GPS location is in the A of the starting station with character " a " (also can adopt other forms), character " a " is added in queue W, enters step 306 afterwards;
If Δ G

Step 306, n=n+1, and judge whether n is less than or equal to N:
If n≤N, then the GPS position information not traveled through buses all in queue T is described, enters step 302;
If n>N, then the GPS position information having traveled through buses all in queue T is described, end step 301 is to the flow process of step 306.
Above-mentioned steps 301 is in the flow process of step 306, if Δ G
na is greater than 200 meters and Δ G
nb is greater than 200 meters, then illustrate that bus n-th GPS location is in the place beyond starting station A and terminus B, bus now is just thought the operating line between starting station A and terminus B is runed.In the present embodiment, the GPS position information being in the bus of operation state does not carry out record in above-mentioned flow process, certainly, as required, also can carry out record.
After above-mentioned steps 301 to the flow process of step 306, comparative result similar to Figure 3 can be obtained.Fig. 3 is the sequence diagram that at starting station A and terminus B stop of bus in the statistics date in the embodiment of the present invention, it should be noted that, content shown in Fig. 3, the statistics not among actual a day, as illustrative purposes only.
Step 4, determine the residence time of described bus at starting station A, the residence time at terminus B, leave described starting station A moment, arrive described terminus B moment, leave the moment of described terminus B and arrive the moment of described starting station A.
Because bus had certain residence time among one day in website (starting station A, terminus B), so, within this period of residence time, whenever arriving the moment of GPS position information of record bus, just the GPS position information of a bus is recorded, so can obtain multiple GPS position information be in website, and the residence time is longer, and the GPS position information be in website is more.
As shown in Figure 3, according in the queue T of time order and function order sequence and the queue W corresponding with it, continuous multiple expression of occurring within a period of time result at starting station A or starting station B can just be obtained.Such as, " the G in queue T
1" arrive " G
6", corresponding to a series of " a " in queue W, this just illustrates at record " G
1" moment of bus GPS positional information start to record " G
6" bus GPS positional information moment during this period of time in, bus is positioned at the region of starting station A, namely during this period of time in bus be positioned at starting station A; " G in queue T
11" arrive " G
15", corresponding to a series of " b " in queue W, this just illustrates at record " G
11" moment of bus GPS positional information start to record " G
15" bus GPS positional information moment during this period of time in, bus is positioned at the region of terminus B, namely during this period of time in bus be positioned at terminus B.
Further, also the time that described bus leaves described starting station A, arrives described terminus B, leaves described terminus B, arrives described starting station A can be obtained, that is: the collection moment (such as " G of the bus GPS positional information corresponding to first " a " in a series of " a " by a series of " a " and a series of " b "
1", " G
19" the collection moment) arrive the moment of described starting station A for described bus; Collection moment (such as " the G of last in a series of " a " the bus GPS positional information corresponding to " a "
6" the collection moment) leave the moment of described starting station A for described bus; Collection moment (such as " the G of the bus GPS positional information corresponding to first " b " in a series of " b "
11" the collection moment) arrive the moment of described terminus B for described bus; Collection moment (such as " the G of last in a series of " b " the bus GPS positional information corresponding to " b "
15" the collection moment) leave the moment of described terminus B for described bus.
As can be seen from above-mentioned explanation, in this step 4:
Determine described bus the residence time of starting station A method for: by the time period corresponding to multiple results being positioned at a-quadrant, the starting station of occurring continuously, be defined as the residence time of described bus at starting station A;
Determine described bus the residence time of terminus B method for: by the time period corresponding to multiple results being positioned at B region, terminus of occurring continuously, be defined as the residence time of described bus at terminus B;
The method that described bus arrives the moment of described starting station A for: by the collection moment of the bus GPS positional information corresponding to multiple first result being arranged in the result of a-quadrant, the starting station of occurring continuously, be defined as the moment that described bus arrives described starting station A;
The method that described bus leaves the moment of described starting station A for: by the collection moment of the bus GPS positional information corresponding to multiple last result being arranged in the result of a-quadrant, the starting station of occurring continuously, be defined as the moment that described bus leaves described starting station A;
The method that described bus arrives the moment of described terminus B for: by the collection moment of the bus GPS positional information corresponding to multiple first result being arranged in the result in B region, terminus of occurring continuously, be defined as the moment that described bus arrives described terminus B;
The method that described bus leaves the moment of described terminus B for: by the collection moment of the bus GPS positional information corresponding to multiple last result being arranged in the result in B region, terminus of occurring continuously, be defined as the moment that described bus leaves described terminus B.
Step 5, determine that described bus runs between the described starting station and terminus total time time.
The normal operation process of bus constantly travels to and fro between the process of starting station A and terminus B.Shown in Fig. 3, the GPS position information not being recorded in a-quadrant, the starting station and B region, terminus between a series of " a " and a series of " b ", is operation bus GPS positional information on the line.So, just can obtain in queue W, when being become a series of " b " from a series of " a ", when becoming again a series of " a " afterwards, then indicate bus from starting station A, and reach terminus B, return again starting station A afterwards, this is the operation that bus completes a time time.So the conversion of a → b → a each time in the queue W shown in Fig. 3, is the operation of bus one time, counts the number of transitions of a → b all in queue W → a, just can obtain total time time that described bus is runed between the described starting station and terminus.
As can be seen from above-mentioned explanation, in this step 5, determine that the method for total time time that described bus is runed between the described starting station and terminus is:
According to time sequencing, the change of the once following order occurred is defined as the operation of bus one time:
