Fig. 5 is that in the embodiment of the present invention, Bus information processing enter is processed the process flow diagram that obtains first kind Bus information to preliminary Bus information.As shown in Figure 5, this process comprises the following steps:

Step 501: flow process starts;

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

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

Step 503: Bus information processing enter is set to 0 by 3-3-Bn;

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

Step 504: whether following two conditions of Bus information processing enter judgement are set up simultaneously, if so, perform step 505, otherwise execution 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, the website sequence number of m the bus station that the bus that 3-3-Am is this public transport fleet 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 is m the bus station that will arrive in the travel route of bus of this public transport fleet.

3-2-Bn be not 0 and 3-3-Am equate that with 3-2-Cn these two conditions set up simultaneously, mean that n bus of this public transport fleet is current in transport condition, and m the bus station that be its travel route, the current bus station having arrived.

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

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

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

Here, Bus information processing enter judges that the method at the Fou Wei starting station, bus station of the current arrival of this bus is: according to the 3-1-A judgement of this bus, if the 3-1-A of this bus is 1, mean that the bus station of the current arrival of this bus is the starting station, otherwise, be not the starting station.

Step 507: be the starting station in the bus station of the current arrival of this bus, determine that next bus running of this public transport fleet is to 3-3-D estimated time at the starting station, this flow process is shown in Fig. 6, then performs step 509;

Step 508: in the case of the Bu Shi starting station, bus station of the current arrival of this bus, determine that next bus running of this public transport fleet is to 3-3-D estimated time of this bus station, this flow process is shown in Fig. 7, then performs step 509;

Step 509: process ends.

Fig. 6 is that the bus station of the current arrival of bus in the embodiment of the present invention determines that next bus running of this public transport fleet is to the process flow diagram of the estimated time at the starting station while being the starting station.As shown in Figure 6, this flow process comprises: the judgement of Bus information processing enter

Step 601: flow process starts;

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

Here, 3-1-C1 is more late than current time, means that this bus not yet arrives the time of departure, needs to continue to stop the starting station until the scheduled departure time arrives; 3-1-C1, unlike current time evening, means that this bus has rolled the starting station away from.

Step 603: 3-3-C1 and 3-3-D1 are set to 0, then perform step 605;

Here, 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 previous bus station, 3-3-D1 is that next bus running of this public transport fleet is to the estimated time at the starting station, before the starting station, there is no bus station, therefore 3-3-C1 need be set to 0, because this bus has rolled the starting station away from, therefore next bus is also about to or has rolled the starting station away from, therefore 3-3-D1 is set to 0.

Step 604: the difference that 3-3-C1 and 3-3-D1 are set to 3-1-C1 and deduct current time gained, then performs step 605;

Here, Bus information processing enter judges that this bus not yet rolls the starting station away from, therefore it is negative value that 3-1-C1 deducts the difference of current time gained, the difference that 3-3-C1 is set to 3-1-C1 and deducts current time gained, means that this bus not yet arrives the scheduled departure time; 3-3-D1 is set to 3-1-C1 and deducts the difference of current time gained, mean 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 determines while being the Bu Shi starting station, bus station of the current arrival of bus in the embodiment of the present invention that next bus running of this public transport fleet is to the process flow diagram of the estimated time of this bus station.As shown in Figure 7, this flow process comprises:

Step 701: flow process starts;

Step 702: put variable X=2;

Here, variable X, for storage site sequence number, is put variable X=2, represents that the current bus station described in 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: determine in the table 3-1 of this public transport fleet with current time apart from minimum arrival time 3-1-Cn, insert variable M;

Here, the line number question blank 3-1 of this public transport fleet obtaining according to step 703, travels through the 3-1-Cn of all bus stations, thereby determines that this public transport fleet obtains in circuit with current time apart from minimum arrival time 3-1-Cn.

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

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

Step 706: 3-3-CX is set to 1-2-Cn and is equated;

Here, the predetermined arrival time of this bus station is in init state, by the bus running of this public transport fleet to the time interval 3-3-CX between X bus station and previous bus station be set to the station of this public transport fleet between the fastest running time 1-2-Cn equate.

Step 707: variable Y and 3-3-CX are placed in variable Y after being added;

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 present invention is provided with variable Y, for the cumulative time interval, 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, determine the value of the 1-2-D of this public transport fleet; Then perform step 712;

Here, put 3-3-DX=Y, mean the time interval after variable Y storage cumulative is placed in to 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 determine 3-2-Em;

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

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

Here, variable M has been set to current time apart from minimum arrival time 3-1-Cn in step 704,3-2-Em is the arrival time of this bus running to a upper bus station, deduct 3-2-Em with M, the difference obtaining is this bus arrives X the bus station time interval from a upper bus station.This embodiment is using the bus that arrives this nearest public transport fleet of the arrival time of this bus station and current time as sample bus, then sample bus is run to the working time of this bus station from a upper bus station, run to the estimated time of this bus station as next bus from a upper bus station.

Step 711: variable Y and variable N are added, insert variable Y, execution step 708;

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

Here, whether 3-3-DX is not more than 1.5*1-2-D, is an index that judges near the traffic congestion situation in X bus station, if so, near X bus station, do not block up, otherwise, may seriously block up, also may 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: whether following two conditions of Bus information processing enter judgement are set up simultaneously, and these two conditions are: X equals 3-2-C; 3-2-C is not equal to 0, if so, performs step successively 718 to 720, otherwise performs step successively 722,723 and 720;

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

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

Here, whether 3-3-DX is not more than 3*1-2-D, is another index that judges near the traffic congestion situation in X bus station, if so, and near slight traffic congestion X bus station, otherwise, be serious traffic congestion.

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

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

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

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

Step 718: variable X adds 1, inserts variable X

Here, variable X adds 1, means the every terms of information that starts to calculate next bus station.

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

Step 720: process ends.

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

Here owing to restarting to calculate the every terms of information of next bus station, therefore, put variable Y=0.

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

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