Step S41, otherwise terminates the scheduling of the quick public transport vehicle to this order of classes or grades at school.
In order to make technical scheme it is more readily appreciated that enter as a example by the scheduling process of bus rapid transit 1 bus below
Row explanation.
As table 1-1 and table 1-2 gives the meter that bus rapid transit 1 bus is corresponding when speed limit is 60km/h and 30km/h
Draw timetable.Travel route and each website of approach of bus rapid transit 1 bus be: the De Mao village (starting station)-Dongying room-six camp gate-
East highland-western depression-three camp gate-and justice southern station-and the adopted-Jiu Jing village, farm-bright red raft of pontoons-West, The Big Red Gate-orchard, Nangyuan District road-
In wooden slippers garden bridge-sand mouth-Gate of Everlasting Stability-the Temple of Heaven-Qianmen (terminus).
The schedule plan of No. 1 corresponding for table 1-1 60km/h bus rapid transit route
The starting station: terminus, the De Mao village: Qianmen
The schedule plan of No. 1 corresponding for table 1-2 30km/h bus rapid transit route
The starting station: terminus, the De Mao village: Qianmen
It is right when speed limit is by 60km/h and 30km/h that table 2-1 and table 2-2 gives the n-th order of classes or grades at school bus rapid transit 1 bus
The execution timetable answered.It is 60km/h and 30km/h that table 2-3 and table 2-4 gives m order of classes or grades at school bus rapid transit 1 bus at speed limit
Time corresponding execution timetable.Described execution timetable is exactly that the running time in described schedule plan is scaled correspondence
Beijing moment, other Information invariabilities.For the quick public transport vehicle of each order of classes or grades at school, it is thus achieved that the method performing timetable is equal
Said method can be used.If bus rapid transit 1 bus of the n-th order of classes or grades at school is 13:30:00 from starting station moment, m order of classes or grades at school
Bus rapid transit 1 bus go out moment from the starting station be 13:45.
The schedule plan of the n-th corresponding for table 2-1 60km/h No. 1 bus rapid transit route of order of classes or grades at school
The starting station: terminus, the De Mao village: Qianmen
The schedule plan of No. 1 bus rapid transit route of the n-th corresponding for table 2-2 30km/h order of classes or grades at school
The starting station: terminus, the De Mao village: Qianmen
The schedule plan of No. 1 bus rapid transit route of m order of classes or grades at school corresponding for table 2-3 60km/h
The starting station: terminus, the De Mao village: Qianmen
The schedule plan of No. 1 bus rapid transit route of the m order of classes or grades at school that table 2-4 30km/h is corresponding
The starting station: terminus, the De Mao village: Qianmen
In such scheme in the present embodiment, be by a certain bar public bus network all websites between information all preserve
To same schedule plan and execution timetable.Reality perform during, it is also possible to select each two adjacent sites it
Between a schedule plan is set, during the execution then obtaining between not two stations according to the schedule plan between each two station
Carve table.When actual motion, between each two station run quick public transport vehicle all according to when set out in advance to make arrangements corresponding to execution time
Quarter, table ran.Its principle is identical, and this does not describes in detail.
And in the scheduling process to quick public transport vehicle, in real time by the longitude and latitude of the quick public transport vehicle under current time
Information (XD, YD) reference position information (X performed in timetable that is currently executing with this order of classes or grades at school quick public transport vehiclei, Yi)
Carry out comparison one by one, it is judged that whether quick public transport vehicle current location is at a certain approach website.If it is need to judge quickly
Whether public transit vehicle difference between the berthing time and benchmark berthing time of this website exceedes the adjustable thresholds of setting.With
As a example by station, the Jiu Jing village, if the benchmark berthing time of regulation is 45 seconds, from the time required for station, the Jiu Jing village to bright red raft of pontoons station
It is divided into 2 minutes, sets adjustable time threshold as the 30% of this time interval, i.e. 36 seconds.If owing to the people that gets on the bus at this station
Number is more, and its berthing time is 1 minute, i.e. extends 15 seconds, within 15 seconds, is less than 36 seconds, now it is believed that from station, the Jiu Jing village to
Reaching in the driving process at bright red raft of pontoons station, driver can make quick public transport vehicle normally according to performing the moment by suitably acceleration
Table row is sailed, then without modifying execution timetable.If the berthing time at this station be 1 point 30 seconds, i.e. extend 45 seconds,
Exceed adjustable thresholds 36 seconds, now it is believed that in from station, the Jiu Jing village to the driving process at bright red raft of pontoons station, driver
It is quick public transport vehicle cannot to be made to travel according to performing timetable by acceleration, needs execution timetable is modified.Amendment
Principle be: the reference instant performed in timetable is all adjusted to Ti+K-Kj.But, due to the quick public transport of different order of classes or grades at school
Departing time interval between and the time interval arriving each approach station are pre-set, if therefore n-th class
The execution timetable of secondary quick public transport vehicle there occurs change, quick with n order of classes or grades at school in order to ensure the quick public transport vehicle of m order of classes or grades at school
The time interval of public transit vehicle is 15 minutes, then the reference instant performed in timetable of the quick public transport vehicle of m order of classes or grades at school also should
This is adjusted to Ti+K-Kj.During reality performs, can be to adjust the quick public transport vehicle performing timetable at first as base
Standard, is adjusted successively to the execution timetable that the quick public transport vehicle of other order of classes or grades at school is corresponding.If the i.e. the 4th order of classes or grades at school is quick public
Hand over car need to carry out above-mentioned adjustment at first, the most 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 enter
Row sum-equal matrix, to ensure that the quick public transport vehicle of adjacent two order of classes or grades at school arrives the same time interval by way of website.Each order of classes or grades at school
Quick public transport vehicle all travels according to the execution timetable after updating.
As a example by table 2-1, it is assumed that the quick public transport vehicle of the n-th order of classes or grades at school is led too much from station, the Jiu Jing village due to the passenger got on or off the bus
The cause dwell time is 45 seconds, has exceeded 36 seconds, has the most now been adjusted table 2-1, has been adjusted to table 2-5.
The schedule plan of the n-th No. 1 bus rapid transit route of order of classes or grades at school that table 2-5 is corresponding for 60km/h after adjusting
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 table 2-3.
The schedule plan of No. 1 bus rapid transit route of m order of classes or grades at school that table 2-6 is corresponding for 60km/h after adjusting
The starting station: terminus, the De Mao village: Qianmen
Benchmark for table 2-6, between the position that the quick public transport vehicle of m order of classes or grades at school is currently located to station, the Jiu Jing village
In the moment, it is adjusted based on the reference instant at station, the Jun Yijiujing village.Thus, it is possible to after showing that the n-th order of classes or grades at school and m order of classes or grades at school adjust
Execution timetable, the execution timetable of the quick public transport vehicle of other order of classes or grades at school is adjusted the most in this manner simultaneously.For
The quick public transport vehicle of each order of classes or grades at school, is all scheduling according to the execution timetable after adjusting.
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
(XD, YD), reference position in execution timetable corresponding with 60km/h speed limit for quick public transport vehicle current position coordinates is carried out
Comparison one by one, find the reference position nearest with current quick public transport vehicle positional distance be longitude be Xn, latitude value is
Yn, obtain T fiducial time that this position is correspondingDFor 14:10:00.It should be noted that the quick public transport vehicle under current time
Position coordinates, upon execution table at quarter may can find the most essentially equal reference position information.But it is most of
In the case of, it is upon execution table at quarter cannot to find the reference position the most corresponding with quick public transport vehicle current location information
Information, the most just according to described above, sit with current time quick public transport vehicle position from performing timetable is searched
The reference position that subject distance is nearest, it is believed that this closest reference position is exactly the current location of quick public transport vehicle.Relatively
Position coordinates (the X of the quick public transport vehicle under current time T and current timeD, YDCorresponding to) reference instant TD: T ≠
TD, now need within the time of regulation, make the actual current location of the current time of quick public transport vehicle, with the execution moment
The reference position corresponding to current time in table coincides.The time of regulation described herein is described in the present embodiment
Time adjusts threshold value TH.Choose according to practical situation, such as, can be chosen as 3S, 5S etc..This time is selected to adjust threshold value
Time to consider to ensure the traveling-position of quick public transport vehicle as early as possible with perform the position of regulation in timetable and overlap, but want simultaneously
