The bus rapid transit being accurate to second arrives at a station information issuing system and method

Technical field

The present invention relates to technical field of control over intelligent traffic, be specifically related to a kind of bus rapid transit being accurate to second and arrive at a station information issuing system and method.

Background technology

Urban highway traffic is city " blood vessel ", and making it unimpeded is the guarantee of urban sustainable development.At present, urban highway traffic supply can not meet transport need far away, result in urban road traffic congestion.The origin cause of formation of urban traffic blocking is multifaceted, and how to meet transport need alleviation traffic congestion from raising public transport efficiency aspect is one of major subjects of traffic administration decision maker care.

Transport need refers to that people for various purposes and thing carry out the requirement of movement in every way in social public space.Therefore, how adopting that handling capacity of passengers is large, speed is fast, take the relatively little vehicles of path area, by people from first ground safety, easily and fast, punctual, comfortable, inexpensively move to second ground, is the target that traffic administration decision maker pursues.

In order to realize this target, bus rapid transit (BRT) is actively being built or opened in domestic and international big and medium-sized cities all, and be that bus rapid transit provides special lane and crossing signals priority function at road and signal control plane, guarantee that bus rapid transit does not disturb by other vehicles in traveling process, do not need by preferentially all-clear can be obtained during crossing to stop.

But in actual trip process, a comparatively outstanding contradiction is exactly cannot know when next class of BRT vehicle can arrive the public that platform is waited for bus, bring not convenient greatly to thus the go off daily of people.Therefore in prior art, a lot of document discloses the real-time traffic information how providing circuit bus by arranging notice board at platform place to the people waited for bus.

As existing patent documentation CN 1305260C discloses a kind of control system for traffic electronic stop plate and method thereof, it can issue vehicle and the related service information of public bus network.As the information processing terminal of public transportation management system, by GPRS wireless communication protocol, set up data communication with the control center of public transportation management system, and information real-time release control center sent, simultaneously can realize remote system upgrade.Utilize said system vehicle location can be prompted to the public and also the excess time of vehicle pull-in can be shown screen display in excess time, and the contents such as other information on services can be demonstrated on LED information display screen, to a great extent for waiting for that passenger by bus provides convenience.But, in real life, the passenger waited for bus is for vehicle position and be indifferent to, but more how long concerned with vehicle arrives at a station in addition, and existing vehicle arrive at a station excess time issue all by minute in units of issue, and the time issued is that the distance got to the station according to current vehicle position calculates with the average overall travel speed that vehicle is current, degree of accuracy is not high, and the vehicle issued at present arrive at a station excess time all by minute in units of, but for catching the people of this order of classes or grades at school vehicle, by minute in units of temporal information precision can not satisfy the demands, it is in one minute that such as five seconds can be calculated, it is in one minute that 50 five seconds also can be calculated, but it is poor therebetween 50 seconds, the passenger driven a cart all may be made to miss a regular bus in each second of difference.Therefore the issue that existing BRT vehicle arrives at a station excess time needs to be accurate to second.

But due to the scheduling aspect at BRT vehicle, also continue traditional bus dispatching method, in prior art, the scheduling of BRT is carried out in the following way: be 1. mounted with on each BRT vehicle and can carry out the GPS locating module of communication transfer with dispatching center, utilize GPS locating module can obtain the real time position of BRT vehicle and be sent to dispatching center; 2. after dispatching center receives the positional information of BRT vehicle, associate with GIS Geographic Information System, match on electronic map road by the positional information of BRT vehicle, dispatcher can see the position of BRT vehicle on electronic chart; 3. dispatcher can transfer the timetable prestored from system, and according to the arrival time recorded in timetable, in conjunction with the scheduling experience scheduling BRT vehicle of dispatcher, commander BRT vehicle arrives website on time.But in prior art, following problem is existed to BRT vehicle scheduling:

(1) for dispatcher, the moment that BRT vehicle arrives website can only be obtained according to timetable, therefore scheduling experience can only be relied on to dispatch according to the moment of BRT vehicle arrival website when dispatching, because the driving habits of driver is different in scheduling process, the problems such as the experimental technology deficiency of dispatcher, BRT vehicle may be caused according to the stipulated time in timetable, website cannot to be arrived with being accurate to second.Especially in rush hour on and off duty, namely 1 to 2 minutes, the interval at the time of departure of BRT vehicle, owing to can not ensure in scheduling process that each BRT vehicle arrives website according to the time of timetable with being accurate to second, often cause many BRT vehicles to arrive a station simultaneously and also do not have the situation of a BRT vehicle pull-in to occur through the longer time, the administrative staff that goes out providing administrative staff especially in a hurry brings inconvenience.

(2) in prior art to the scheduling of BRT vehicle, carry out according to the scheduling experience of dispatcher and the driving experience of driver, unified standard cannot be had, therefore the timetable formulated can only as secondary reference of arranging an order according to class and grade, because according to the data in same timetable, dispatched by different dispatchers, different drivers drives, its scheduling result can be had nothing in common with each other, can not ensure that BRT vehicle arrives each website with being accurate to second completely, make troubles to the people of trip, and be unfavorable for the operation ability improving BRT vehicle.

(3) in prior art to the scheduling of BRT vehicle, that dispatch command is handed down to BRT vehicle by dispatching center by the form of data communication by dispatcher, therefore once BRT vehicle and dispatching center's communicating interrupt, just cannot implement scheduling, what more can not ensure scheduling is accurate to second.

(4) in prior art, vehicle location information is obtained by vehicle GPS, but the signal of vehicle GPS is easy to be blocked by buildings, trees, bridge, tunnel etc., vehicle drives to gps signal under tunnel, viaduct when being subject to blocking, when GPS cannot determine current vehicle position, technique scheme cannot guarantee that quick public transport vehicle arrives each website with can being accurate to second.

Owing to there are the problems referred to above to the scheduling of quick public transport vehicle in prior art, therefore can only using minute as the minimum time of day of scheduling instance table, second can not be accurate to, so the nearest regular bus information of arriving at a station that the Information Points such as LED display are issued be by minute in units of estimated value, cannot realize releases news is accurate to second, makes troubles to passenger in a hurry.

Described electronic information display unit 6 receives the data sent from the described extraction module 14 that releases news by described 3rd data communication unit 23, show arriving at a station excess time of the vehicle that enters the station recently with being accurate to second.

The bus rapid transit of what the present embodiment provided be accurate to second arrives at a station information issuing method, comprises the steps:

I. schedule plan is generated

In practical implementation, whether the data acquisition that the driving habits of each driver and driving experience can have influence in schedule plan is accurate, therefore the mode chosen driver Shi Ke and take everybody to elect, select the outstanding driver generally acknowledged to obtain schedule plan, preferred driver obtains data and can be used as the benchmark that all drivers observe;

In this step, the quick public transport vehicle utilized is identical with the quick public transport vehicle in actual moving process, quick public transport vehicle is also provided with vehicle GPS positioning unit and vehicle-mounted odometer counting unit, utilize vehicle GPS positioning unit record quick public transport vehicle position coordinates as reference position coordinate, utilize vehicle-mounted odometer counting unit record distance travelled as benchmark mileage, be stored in schedule plan;

Conveniently distinguish different bus rapid transit routes and different websites, in the present embodiment, also comprise the step of numbering respectively for every bar bus rapid transit route and each website thereof; Obtain in this step thus each described in schedule plan all there is the identification number relevant to bus rapid transit route site number.When being numbered for quick public transport Road, can various ways be adopted, as long as different quick public transport Roads can be made a distinction, can different quick public transport Road be numbered arabic numeral in the present embodiment.

For bus rapid transit 1 bus (hereinafter referred to as fast 1), fast 1 by way of stop website have: in highland, De Mao village-Dongying room-six camp gate-Dong-Xi depression-three camp gate-and adopted southern station-and-Jiu Jing village, adopted farm-bright red raft of pontoons-West, The Big Red Gate-orchard, Nangyuan District road-wooden slippers garden bridge-sand mouth-Gate of Everlasting Stability-the Temple of Heaven-Qianmen;

If the bus routes corresponding to fast 1 is numbered " 1 ", being numbered " 101 " of its Sino-German Mao Zhuan station, being numbered " 102 " of station, Dongying room, the rest may be inferred, being numbered " 117 " of station, Qianmen.

When obtaining schedule plan, the quick public transport vehicle being arranged vehicle GPS positioning unit 4 and vehicle-mounted odometer counting unit 5 by driver travels to station, Dongying room (102) from station, the De Mao village (101) in advance according to the speed of regulation, obtain the schedule plan shown in table 1, if the identification number of table 1 is " 1001 ", obtaining the schedule plan shown in table 2 is equally schedule plan from station, Dongying room (102) to six camp gate stations (103), if its identification number is " 1002 ".As shown in Table 1 and Table 2, the benchmark mileage number that the coordinate that record the reference position that quick public transport vehicle should arrive p.s. in schedule plan should travel p.s., and be reference position by first described reference position, corresponding running time is initial time; Record in described schedule plan last described in reference position be in-position, corresponding running time is time of arrival;

Table 1 schedule plan-1001

Starting station: arrival station, the De Mao village: Qianmen

No.-1002, table 2 schedule plan

Originating station: Dongying room (102) bus stop: six camp gates (103)

Schedule plan as shown in Table 1 and Table 2, the value of described longitude and latitude is all detected by vehicle positioning unit 4 and obtains, and is not associated with electronic map road.The in-position that it should be noted that in the schedule plan of No. 1001 is exactly that reference position in the schedule plan of No. 1002 is identical in fact, and just due in different schedule plans, the representation therefore adopted is different.

By that analogy, the schedule plan between all adjacent two stations on whole piece route can be obtained, and the in-position of previous schedule plan is identical with the starting position coordinates of next schedule plan.

II. generating run timetable

Transfer all schedule plans relevant to a bus rapid transit route, according to frequency, each down time of stopping website of each order of classes or grades at school quick public transport vehicle of this route, by the running time t in described schedule plan _ichange the corresponding local time into as reference instant, formed and show one group of time of running corresponding with each order of classes or grades at school quick public transport vehicle; Is shown the quick public transport vehicle terminal sending to dispatching center's terminal and wait to dispatch a car all described times of running;

If fast 1 bus of the n-th order of classes or grades at school is 12:30:00 from the De Mao village (101) the station moment, namely initial time answers corresponding 12:30:00, add the running time in No. 1001 schedule plans, the local time corresponding when quick public transport vehicle arrives any one reference position between two stations can be released, then can obtain according to watch 1 fast 1 bus of the n-th order of classes or grades at school No. 1001 the times of running table as shown in table 3.

The table time of running that No. 1001, table 3

Originating station: the De Mao village (101) bus stop: Dongying room (102)

Being located at Dongying room (102) down time of standing is 30 seconds, then in table No. 1002 times of running from the moment at Dongying room (102) station should be just show No. 1001 times of running in arrive station, Dongying room moment 12:35:00 add that down time, 30s drew, can obtain from the moment at station, Dongying room be 12:35:30, the table No. 1002 times of running that can obtain fast 1 bus is thus as shown in table 4.

The table time of running that No. 1002, table 4

Originating station: Dongying room (102) bus stop: six camp gates (103)

Contrasted by table 3 and table 1, and table 4 contrasts known with table 2, described time of running, table was exactly the local time running time in described schedule plan being scaled correspondence, other Information invariabilities.The like, all time of running table of quick public transport vehicle in operational process can be obtained.

III. route schematic diagram is generated

IV. dispatch command is generated

To show No. 1002 times of running in the present embodiment, then initial time is 12:35:30, and time of arrival is 12:41:30; Suppose that current time T is 12:35:34, obviously its be greater than No. 1002 the time of running table record initial time and be less than No. 1002 the time of running table record time of arrival;

Such as when current time T is 12:35:34, quick public transport vehicle current actual positions coordinate (x detected _d, y _d), described multilevel iudge module 34 is by quick public transport vehicle current actual positions coordinate (x _d, y _d) with the time of running show in reference position carry out comparison one by one, finding the reference position coordinate nearest with current quick public transport vehicle positional distance is (x ₃, y ₃), obtain T reference time that this position is corresponding _dfor 12:35:31; Meanwhile, in being shown the time of running, 12:35:31 and benchmark mileage corresponding afterwards thereof, deduct mileage number corresponding to reference instant 12:35:31 5.00 successively;

Then the time of running, table will be deformed into:

During table 5 12:35:31, the time of running of No. 1002 is shown

Originating station: Dongying room (102) bus stop: six camp gates (103)

Adopt this method can eliminate cumulative errors because operating range far brings, as common practise, can know, metering for Vehicle-Miles of Travel is that the diameter of the number of turns and the wheel turned over according to wheel obtains, and technician is difficult to ensure that the diameter of wheel always remains on identical numerical value, therefore outstanding driver drives the mileage number recorded in quick public transport vehicle driving process in advance, with the mileage number recorded during actual travel, very likely not identical, because the diameter of wheel there occurs change due to the aeration quantity difference of tire, so can cumulative errors be there are after long distance travel, this cumulative errors are eliminated owing to being reset by mileage number in real time in the present embodiment.

S4, transfer the described time of running table, read the actual travel mileage number S of quick state vehicle current time _d; Quick public transport vehicle actual travel mileage number is associated with immediate benchmark mileage with it in the table described time of running, the reference instant of its correspondence is set to T _d; Obviously now, the mileage number read has been not cumulative mileage number, but the mileage number that time that can read quick public transport vehicle position coordinates from upper one second, therefore can eliminate cumulative errors;

According to table 5, if be the 12:35:32 moment at T, GPS locator module 321 can't detect the position coordinate value of quick public transport vehicle, then read the mileage number that now mileage counting submodule 322 records, if now mileage counting submodule 322 record mileage number be 25.00m, with show the time of running in benchmark mileage S ₄association, S ₄corresponding reference instant T _dfor 12:35:34;

If during Cw≤C, judge that quick public transport vehicle normally travels;

Select described deviation alarm threshold value C to be 1s, thus, calculate mistiming Cw=|T-T by multilevel iudge module 34 _d| be 3 seconds, be greater than C, and T-T _dbe negative, therefore advanced 3 seconds of quick public transport vehicle;

S6, quick public transport vehicle are by the reference instant T corresponding to current time T and quick public transport vehicle current time physical location or actual travel mileage _ddifference distinguish display in seconds, prompting driver regulate the speed; In dispatching center by representing that intention is by the reference instant T corresponding to reference position corresponding for current time T point and quick public transport vehicle current time physical location or actual travel mileage the described time of running _dcorresponding reference position point difference is presented at and represents in intention the described time of running; Prompting driver will remain the reference position point that current time T is corresponding and quick public transport vehicle current time physical location or the reference instant T corresponding to actual travel mileage _dcorresponding reference position point is in coincidence status;

Figure 4 shows that the reference position point that current time that described deviation display module 35 shows is corresponding and the reference position point T corresponding to quick public transport vehicle current time physical location _dschematic diagram; The time that current time T is corresponding is as shown in the figure 08:00:11, and the time that the reference instant TD that quick public transport vehicle current actual positions is corresponding is corresponding is 08:00:14, and obvious quick public transport vehicle travels advanced 3 seconds.In the present embodiment, the reference position point that described deviation display module 35 shows is 9, and by reference position corresponding for current time point in centre position, in quick public transport vehicle operational process, As time goes on, the moment representated by the point of reference position also passes backward.Further, in actual moving process, more reference position point can be shown.When quick public transport vehicle is advanced or exceed the scope of said reference point retardation time, directly can adopt digital prompt, such as, according to Fig. 4, when advanced 13 seconds of quick public transport vehicle, can not be prompted to driver by the reference position point shown in Fig. 4, now deviation directly can be prompted to driver by described deviation display module 35, as " advanced 13 seconds ".

In dispatching center, be illustrated in figure 5 a kind of form of expression, adopt "●" to represent reference position point corresponding to the reference instant that quick public transport vehicle current actual positions is corresponding in Fig. 5, adopt represent the reference position point that current time is corresponding, quick public transport vehicle for different order of classes or grades at school can adopt different colors to distinguish, the picture being black and white due to this figure can not be distinguished according to color, therefore numerical reference order of classes or grades at school is adopted in the symbol top of correspondence: as " B3 " represents the 3rd order of classes or grades at school, " R12 " represents the 12nd order of classes or grades at school, " G18 " represents the 18th order of classes or grades at school, " Y19 " represents the 19th order of classes or grades at school, but different colours can be utilized during actual motion to represent the vehicle of different order of classes or grades at school, such as adopt blue expression the 3rd order of classes or grades at school, adopt red expression the 12nd order of classes or grades at school, adopt green expression the 18th order of classes or grades at school, adopt yellow expression the 19th order of classes or grades at school etc., as the mode that can realize, quick public transport vehicle for different order of classes or grades at school can take different shapes and represent, such as the 3rd order of classes or grades at school can adopt triangle to represent, 12nd order of classes or grades at school can adopt rectangle to represent, 18th order of classes or grades at school can adopt rhombus to represent, the 19th order of classes or grades at school can adopt pentagram shape to represent etc.

Dispatcher can exercise supervision to the situation of scheduling in dispatching center, as can be seen from the figure dispatches whether be accurate to second.Be described for Fig. 5, obviously can obtain, for the 3rd order of classes or grades at school quick public transport vehicle and the 19th order of classes or grades at school quick public transport vehicle, two points overlap, and obviously the quick public transport vehicle of this two order of classes or grades at school normally travels according to the regulation that the time of running is shown.And for the 18th order of classes or grades at school quick public transport vehicle, the reference position point corresponding to the reference instant that quick public transport vehicle current actual positions is corresponding surpasses reference position point corresponding to the first two point current time, therefore belong to advanced traveling, and advanced two seconds; For the 12nd order of classes or grades at school quick public transport vehicle, the reference position point that delayed four the some current times of the reference position point corresponding to the reference instant that quick public transport vehicle current actual positions is corresponding are corresponding, therefore belongs to delayed traveling, and delayed four seconds.

Generally driver can revise voluntarily according to above-mentioned prompting, if because certain reason is not revised, dispatcher can to not sending schedule information according to the driver of the quick public transport vehicle that the time of running, table row was sailed, also can adopt the form such as phone, note driver, thus ensure the degree of accuracy of scheduling further.
