In such scheme in the present embodiment, be by a certain bar public bus network all websites between information be all saved to same schedule plan and perform in timetable.In the process that reality performs, also can select to arrange a schedule plan between every two adjacent sites, then obtain the execution timetable not between two stations according to the schedule plan between every two stations.When actual motion, the quick public transport vehicle run between every two stations all runs according to when the execution timetable corresponding to next stop.Its principle is identical, and this does not describe in detail.

And in the scheduling process of quick public transport vehicle, in real time by the latitude and longitude information (X of the quick public transport vehicle under current time _d, Y _d) with the current execution timetable performed of this order of classes or grades at school quick public transport vehicle in reference position information (X _i, Y _i) carry out comparison one by one, judge that whether quick public transport vehicle current location is at a certain approach website.If it is need to judge whether the difference of quick public transport vehicle between the berthing time and benchmark berthing time of this website exceedes the adjustable thresholds of setting.For station, the Jiu Jing village, if the benchmark berthing time of regulation is 45 seconds, the time interval required for from station, the Jiu Jing village to bright red raft of pontoons station is 2 minutes, and setting adjustable time threshold is 30% of this time interval, namely 36 seconds.If because the number of getting on the bus at this station is more, its berthing time is 1 minute, namely 15 seconds are extended, within 15 seconds, be less than 36 seconds, now can think and arrive from station, the Jiu Jing village in the driving process at bright red raft of pontoons station, driver can by suitably accelerating to make quick public transport vehicle normally according to execution timetable traveling, then without the need to modifying to execution timetable.If the berthing time at this station be 1 point 30 seconds, namely 45 seconds are extended, exceed adjustable thresholds 36 seconds, now can think, in from station, the Jiu Jing village to the driving process at bright red raft of pontoons station, driver cannot make quick public transport vehicle travel according to execution timetable by acceleration, needs to modify to execution timetable.The principle of amendment is: the reference instant performed in timetable is all adjusted to T _i+ K-K _j.But, due to different order of classes or grades at school quick public transport vehicle between departing time interval and time interval of arriving each approach station be pre-set, if therefore the execution timetable of the quick public transport vehicle of the n-th order of classes or grades at school there occurs change, in order to the time interval of the quick public transport vehicle and n order of classes or grades at school quick public transport vehicle that ensure m order of classes or grades at school is 15 minutes, then the reference instant in the execution timetable of the quick public transport vehicle of m order of classes or grades at school also should be adjusted to T _i+ K-K _j.In the process that reality performs, can to adjust the quick public transport vehicle of execution timetable at first for benchmark, the execution timetable corresponding to the quick public transport vehicle of other order of classes or grades at school adjusts successively.If namely the quick public transport of the 4th order of classes or grades at school needs to carry out above-mentioned adjustment at first, then successively to the 5th order of classes or grades at school, the 6th order of classes or grades at school, the 7th order of classes or grades at school ... quick public transport vehicle adjust, with ensure adjacent two order of classes or grades at school quick public transport vehicle arrive the same time interval by way of website.The quick public transport vehicle of each order of classes or grades at school all travels according to the execution timetable after renewal.

To show 2-1, suppose that the quick public transport vehicle of the n-th order of classes or grades at school causes the dwell time to be 45 seconds from station, the Jiu Jing village due to the passenger got on or off the bus too much, exceeded 36 seconds, then now his-and-hers watches 2-1 adjusts, and is adjusted to table 2-5.

The schedule plan of the n-th order of classes or grades at school No. 1 bus rapid transit route that 60km/h is corresponding after table 2-5 adjustment

The starting station: terminus, the De Mao village: Qianmen

And the time interval between the quick public transport vehicle of the quick public transport vehicle of m order of classes or grades at school and the n-th order of classes or grades at school is 15 minutes, therefore the current execution instant table of the quick public transport vehicle of m order of classes or grades at school is adjusted to table 2-6 by showing 2-3.

The schedule plan of the m order of classes or grades at school No. 1 bus rapid transit route that 60km/h is corresponding after table 2-6 adjustment

The starting station: terminus, the De Mao village: Qianmen

For table 2-6, the reference instant between position to the station, the Jiu Jing village at the current place of quick public transport vehicle of m order of classes or grades at school, adjusts based on the reference instant at station, the Jun Yijiujing village.Thus, can draw the execution timetable after the n-th order of classes or grades at school and the adjustment of m order of classes or grades at school, the execution timetable of the quick public transport vehicle of other order of classes or grades at school also adjusts in this manner simultaneously.For the quick public transport vehicle of each order of classes or grades at school, all dispatch according to the execution timetable after adjustment.

Such as when current time T is 14:09:58, detect that the position coordinates of the quick public transport vehicle of the n-th order of classes or grades at school is (X _d, Y _d), comparison is one by one carried out in reference position in execution timetable corresponding with 60km/h speed limit for quick public transport vehicle current position coordinates, and to find the reference position nearest with current quick public transport vehicle positional distance be longitude is X _n, latitude value is Y _n, obtain T reference time that this position is corresponding _dfor 14:10:00.It should be noted that, the position coordinates of the quick public transport vehicle under current time, may can find reference position information completely equal with it in execution timetable.But in most cases, cannot find the reference position information completely corresponding with quick public transport vehicle current location information in execution timetable, now just according to described above, from execution timetable, search the reference position nearest with current time quick public transport vehicle position coordinates, think that this nearest reference position is exactly the current location of quick public transport vehicle.Compare the position coordinates (X of the quick public transport vehicle under current time T and current time _d, Y _d) corresponding to reference instant T _d: T ≠ T _d, now need in official hour, make the current location of the reality of the current time of quick public transport vehicle, coincide with the reference position corresponding to the current time performed in timetable.Official hour described herein is the time adjustment threshold value T described in the present embodiment _h.Choose according to actual conditions, such as, can be chosen as 3S, 5S etc.The traveling-position will considering to ensure quick public transport vehicle when selecting this time to adjust threshold value as early as possible with perform in timetable the position specified and overlap, but the size of present deviation value will be considered simultaneously, when deviate is larger, this time adjustment threshold value can select larger value, also suitably the time can be adjusted threshold value when deviation is less to reduce, consider that the travel speed after quick public transport vehicle adjustment can not exceed the speed limit in this section simultaneously again.

In order to make the above-mentioned situation described in the present embodiment more clear, composition graphs 3 and Fig. 4 are described.

As shown in Figure 3, each point represents a reference position, and the reference position that current time T is corresponding is set as (X _i, Y _i), corresponding benchmark mileage is S _i; The reference position that the quick public transport vehicle latitude and longitude information of the reality under current time T is corresponding is (X _d, Y _d), corresponding benchmark mileage is S _d; Current time T adds time adjustment threshold value T _hcorresponding reference position is set as (X _h, Y _h), corresponding benchmark mileage is S _h.Obviously, when as shown in Figure 3, the reference position that the reference position corresponding to current time T quick public transport vehicle physical location and benchmark mileage should be corresponding than current time in timetable and benchmark mileage advanced.Its traveling-position overlaps with the traveling-position performed in timetable to suppose to require quick public transport vehicle to ensure after 6S, then need quick public transport vehicle at time T _hinterior from reference position (X _d, Y _d) travel to reference position (X _h, Y _h), namely its mileage travelled is S _h-S _d.Therefore, the travel speed required for quick public transport vehicle is V _t=(S _h-S _d)/T _h.

Shown in Fig. 4, shown in situation with Fig. 3, situation is contrary, is the situation of the delayed traveling of quick public transport vehicle.But as can be seen from the figure, if want quick public transport vehicle to overlap with execution timetable after time adjustment threshold value, the travel speed required for it is still V _t=(S _h-S _d)/T _h.

And once the traveling-position of quick public transport vehicle can overlap to performing the corresponding traveling-position recorded in timetable, then can point out and make quick public transport vehicle travel according to the datum velocity corresponding to next reference instant.

As one preferred embodiment, in described step S1, S4, latitude and longitude information, the running time of guide-car before adopting the GPS locating module be arranged on front guide-car to obtain; The distance travelled that before adopting the OBD module be arranged on front guide-car to obtain, guide-car is real-time and travel speed.
