Fig. 5 handles the process flow diagram that obtains first kind Bus information for Bus information processing enter in the embodiment of the invention to preliminary Bus information.As shown in Figure 5, this process may further comprise the steps:

Step 501: flow process begins;

Step 502: the Bus information processing enter is changed to 3-3-An with 3-1-An and equates;

Here, 3-3-An for the bus of this public transport fleet the website sequence number of n the bus station that will arrive, 3-1-An is the website sequence number of n bus station of preliminary this public bus network that Bus information showed, this step can be confirmed 3-3-An.

Step 503: the Bus information processing enter is changed to 0 with 3-3-Bn;

Here, 3-3-Bn is bus station and the vehicle fleet between the next bus station of the current arrival of bus of this public transport fleet, and 3-3-Bn is changed to 0, is that 3-3-Bn is carried out initialization.

Step 504: the Bus information processing enter judges whether following two conditions are set up simultaneously, if then execution in step 505, otherwise execution in step 506, these two conditions are respectively: 3-2-Bn is not 0; 3-3-Am equates with 3-2-Cn;

Here, 3-2-Bn is the idle marker of n bus of this public transport fleet, and 3-2-Bn is not 0, means that this state's car is in transport condition, if 3-2-Bn is 0, means that this bus is in idle condition.

3-2-Cn is the bus station sequence number of n the current arrival of bus of this public transport fleet; 3-3-Am for the bus of this public transport fleet the website sequence number of m the bus station that will arrive; If 3-2-Cn and 3-3-Am equate, the bus station that means n the current arrival of bus of this public transport fleet be in the travel route of bus of this public transport fleet m the bus station that will arrive.

3-2-Bn 0 equates with 3-2-Cn that with 3-3-Am these two conditions set up simultaneously, mean the current transport condition that is in of n bus of this public transport fleet, and the current bus station that has arrived is m bus station of its travel route.

Step 505: if described two conditions of step 504 are set up simultaneously, then 3-3-Bm adds 1, execution in step 506;

Here; Described two conditions of step 504 are set up simultaneously; Then the vehicle fleet 3-3-Bm between m bus station in the travel route of the bus of this public transport fleet and m+1 the bus station is added 1, represent that the bus number that belongs to this public transport fleet between these two bus stations has increased by one.

Step 506: the Bus information processing enter judges whether the bus station of the current arrival of this bus is the starting station, if then execution in step 507, otherwise execution in step 508;

Here; The Bus information processing enter judges that the bus station of the current arrival of this bus for the method at the starting station is not: the 3-1-A according to this bus judges, if the 3-1-A of this bus is 1, means that then the bus station of the current arrival of this bus is the starting station; Otherwise, be not the starting station.

Step 507: in the bus station of the current arrival of this bus is under the situation at the starting station, confirms the estimated time 3-3-D of next bus running of this public transport fleet to the starting station, and this flow process is seen Fig. 6, and execution in step 509 then;

Step 508: in the bus station of the current arrival of this bus is not under the situation at the starting station, confirms the estimated time 3-3-D of next bus running of this public transport fleet to this bus station, and this flow process is seen Fig. 7, and execution in step 509 then;

Step 509: process ends.

Fig. 6 confirms the process flow diagram of next bus running of this public transport fleet to the estimated time at the starting station during for the starting station for the bus station of the current arrival of bus in the embodiment of the invention.As shown in Figure 6, this flow process comprises: the Bus information processing enter is judged

Step 601: flow process begins;

Step 602: the Bus information processing enter judges whether the bus of this public bus network is more late than the current time at the arrival time 3-1-C1 at the starting station, if then execution in step 604, otherwise execution in step 603;

Here, 3-1-C1 is more late than the current time, means this bus no show still time of departure, needs to continue to stop the starting station and arrives until the scheduled departure time; 3-1-C1 means that unlike evening current time this bus has rolled the starting station away from.

Step 603: 3-3-C1 and 3-3-D1 are changed to 0, and execution in step 605 then;

Here, the Bus information processing enter judges that this bus has rolled the starting station away from.

3-3-C1 is that the bus running of this public transport fleet is to the time interval between the starting station and the previous bus station; 3-3-D1 is the estimated time of next bus running of this public transport fleet to the starting station; Because front, the starting station does not have the bus station, thus need 3-3-C1 is changed to 0, because this bus has rolled the starting station away from; So next bus also is about to or has rolled the starting station away from, so 3-3-D1 is changed to 0.

Step 604: 3-3-C1 and 3-3-D1 are changed to the difference that 3-1-C1 deducts the current time gained, and execution in step 605 then;

Here; The Bus information processing enter judges that this bus does not roll the starting station as yet away from; So it is negative value that 3-1-C1 deducts the difference of current time gained, and 3-3-C1 is changed to the difference that 3-1-C1 deducts the current time gained, means this bus no show scheduled departure still time; 3-3-D1 is changed to the difference that 3-1-C1 deducts the current time gained, means that still need time of absolute value length of this difference of this bus just can roll the starting station away from.

Step 605: flow process finishes.

Fig. 7 confirms the process flow diagram of next bus running of this public transport fleet to the estimated time of this bus station when being not the starting station for the bus station of the current arrival of bus in the embodiment of the invention.As shown in Figure 7, this flow process comprises:

Step 701: flow process begins;

Step 702: put variable X=2;

Here, variable X is used for the storage site sequence number, puts variable X=2, and the current bus station described in the expression later step is the 2nd bus station.

Step 703: utilize the website code name of X bus station and previous bus station, question blank 1-4 obtains the line number of the public transport fleet under this bus;

Step 704: confirm among the table 3-1 of this public transport fleet and the arrival time 3-1-Cn of current time, insert variable M apart from minimum;

Here,, travel through the 3-1-Cn of all bus stations, thereby confirm that this public transport fleet gets in the circuit and the arrival time 3-1-Cn of current time apart from minimum according to the line number question blank 3-1 of resulting this public transport fleet of step 703.

Step 705: the Bus information processing enter judges whether this 3-1-Cn equals 0FFFFFF, if, execution in step 706,707 and 708 successively then, otherwise execution in step 709,710,711 and 708 successively;

Here, step 704 confirm with the current time be 0FFFFFF apart from the arrival time 3-1-Cn of minimum, mean that the predetermined arrival time of this bus station is in init state, first car of this public transport fleet do not dispatched a car as yet.

Step 706: 3-3-CX is changed to 1-2-Cn equates;

Here; The predetermined arrival time of this bus station is in init state, then the bus running of this public transport fleet is changed to the time 1-2-Cn that drives a vehicle the soonest between the station with this public transport fleet to X bus station and time interval 3-3-CX between the previous bus station and equates.

Step 707: after variable Y and the 3-3-CX addition, place variable Y;

Here; Because next bus that arrives X bus station is not necessarily between X bus station and X+1 bus station; Therefore; The embodiment of the invention is provided with variable Y, is used to the time interval of adding up, thereby the bus that finally obtains next X bus station of arrival arrives the estimated time of X bus station.

Step 708: put 3-3-DX=Y, utilize the line number of this public transport fleet, confirm the value of the 1-2-D of this public transport fleet; Execution in step 712 then;

Here, put 3-3-DX=Y, mean the time interval after the adding up of variable Y storage is placed 3-3-CX.

1-2-D is average running time between the station of this public transport fleet.

Step 709: utilize 3-1-Dn to confirm 3-2-Em;

Here, 3-1-Dn is next car sequence number that arrives the bus of X bus station, and 3-2-Em is the arrival time of this bus running to a last bus station.

Step 710: the difference that variable M is deducted 3-2-Em is inserted variable N, puts 3-3-CX=variable N;

Here; Variable M has been changed in step 704 and the arrival time 3-1-Cn of current time apart from minimum; 3-2-Em is the arrival time of this bus running to a last bus station; Deduct 3-2-Em with M, the difference that obtains arrives the time interval of X bus station from a last bus station for this bus.This embodiment will arrive the bus of this nearest public transport fleet of arrival time and current time of this bus station as the sample bus; Then the sample bus is run to the working time of this bus station from a last bus station, run to the estimated time of this bus station as next bus from a last bus station.

Step 711:, insert variable Y, execution in step 708 with variable Y and variable N addition;

Step 712: the Bus information processing enter judges whether 3-3-DX is not more than 1.5*1-2-D, if, execution in step 713 and 714 successively then, otherwise execution in step 715;

Here, whether 3-3-DX is not more than 1.5*1-2-D, is an index judging near the traffic congestion situation in X bus station, if, then do not block up near X bus station, otherwise, possibly seriously block up, also possibly slightly block up.

Step 713: put 3-3-EX=0x0F;

Here, 3-3-EX=0x0F does not block up near meaning X bus station.

Step 714: the Bus information processing enter judges whether following two conditions are set up simultaneously, and these two conditions are: X equals 3-2-C; 3-2-C is not equal to 0, if, execution in step 718 to 720 successively then, otherwise execution in step 722,723 and 720 successively;

Here, 3-2-C is the bus station sequence number of the current arrival of this bus.

Step 715: the Bus information processing enter judges whether 3-3-DX is not more than 3*1-2-D, if then execution in step 716, otherwise execution in step 717;

Here, whether 3-3-DX is not more than 3*1-2-D, is another index of judging near the traffic congestion situation in X bus station, if, then slightly block up near X bus station, otherwise, be serious traffic congestion.

Step 716: put 3-3-EX=0xF0, execution in step 714 then;

Here, put 3-3-EX=0xF0, mean near slight traffic congestion X the bus station.

Step 717: put 3-3-EX=0xFF, execution in step 714 then;

Here, put 3-3-EX=0XFF, mean near serious traffic congestion X the bus station.

Step 718: variable X adds 1, inserts variable X

Here, variable X adds 1, means each item information that begins to calculate next bus station.

Step 719: the Bus information processing enter judges whether X station is the last leg, is execution in step 720 then, otherwise execution in step 721;

Step 720: process ends.

Step 721: put variable Y=0, execution in step 703;

Here, owing to restart to calculate each item information of next bus station, therefore, put variable Y=0.

Step 722: variable X adds 1, inserts variable X;

Step 723: the Bus information processing enter judges whether X station is the last leg, is execution in step 720 then, otherwise execution in step 703.
