Description

The bus rapid transit be accurate to second arrive at a station internet information delivery system and method

Technical field

The present invention relates to intelligent transportation control technology field, be specifically related to a kind of bus rapid transit be accurate to second arrive at a station internet information delivery system and method.

Background technology

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

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

In order to realize this target, bus rapid transit (BRT) is actively being built or opened in big and medium-sized cities all both at home and abroad, and special lane and crossing signal priority function are provided at road and signal controlling aspect for bus rapid transit, guarantee that bus rapid transit is not disturbed by other vehicles in traveling process, can preferentially obtain all-clear during by crossing and do not need to stop.

But, in actual trip process, a comparatively outstanding contradiction is exactly the passenger for the inquiry of having no way of of the operation conditions of BRT vehicle, can't Obtaining Accurate oneself want the running state information of the BRT vehicle taken; Especially when the passenger need to make up for lost time, can't inquire about oneself and whether can get to the station before the one class of vehicle arrived at a station recently enters the station.Therefore for the passenger, the information of arriving at a station how to obtain easily and efficiently quick public transport vehicle is necessary.

And, in real life, the part station setting has electronic information to show that station board shows the excess time of arriving at a station of nearest one class of vehicle, and still can't obtain this information for not having the passenger who waits for bus at platform; In addition, and the vehicle arrival time of at present issue all to take minute be unit, but for the people who catches this order of classes or grades at school vehicle, take minute as the temporal information precision of unit and can not satisfy the demands, for example can to calculate be in one minute to five seconds, it is in one minute that 50 five seconds also can be calculated, but poor therebetween 50 seconds, all may make each second differed the passenger who drives a cart miss a regular bus.Therefore the issue of existing BRT vehicle arrival time need to be accurate to second.

But due to the scheduling aspect at the BRT vehicle, also continue traditional bus dispatching method, scheduling to BRT in prior art is carried out in the following way: 1. on each BRT vehicle, be mounted with and can carry out the GPS locating module of communication transfer with dispatching center, utilize the 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, with the GIS Geographic Information System, carry out associatedly, the positional information of BRT vehicle is matched on electronic map road, the dispatcher can see the position of BRT vehicle on electronic chart; 3. the dispatcher can transfer pre-stored good timetable from system, and according to the arrival time of putting down in writing in timetable, in conjunction with dispatcher's scheduling experience scheduling BRT vehicle, commander BRT vehicle arrives website on time.But in prior art, to BRT, there is following problem in vehicle scheduling:

(1) for the dispatcher, can only obtain the moment that the BRT vehicle arrives website according to timetable, therefore when scheduling, can only rely on the scheduling experience to be dispatched according to the moment of BRT vehicle arrival website, in scheduling process due to driver's driving habits difference, the problems such as dispatcher's experimental technology deficiency, may cause the BRT vehicle according to the stipulated time in timetable, to be accurate to second ground and to arrive website.Especially in rush hour on and off duty, namely 1 to 2 minute, the interval at the time of departure of BRT vehicle, owing to can not guaranteeing in scheduling process that each BRT vehicle is accurate to the time arrival website of second ground according to timetable, the situation appearance that often causes many BRT vehicles to arrive a station simultaneously and also there is no a BRT vehicle pull-in through the longer time, provide the especially in a hurry administrative staff that goes out of administrative staff and brought inconvenience.

(2) in prior art to the scheduling of BRT vehicle, to carry out according to dispatcher's scheduling experience and driver's driving experience, unified standard can't be arranged, therefore the timetable of formulating can only be as the inferior reference of arranging an order according to class and grade, because according to the data in same timetable, by different dispatchers, dispatched, different drivers are driven, its scheduling result can be had nothing in common with each other, can not guarantee that the BRT vehicle is accurate to second ground and arrives each website fully, make troubles to the people of trip, and be unfavorable for improving the operation ability of BRT vehicle.

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

(4) in prior art, obtain vehicle location information by vehicle GPS, but the signal of vehicle GPS is easy to be blocked by buildings, trees, bridge, tunnel etc., when Vehicle Driving Cycle is subject to blocking to gps signal under tunnel, viaduct, GPS can't determine in the situation of vehicle current location, and technique scheme can't guarantee that the quick public transport vehicle can be accurate to second ground and arrive each website.

Because there are the problems referred to above in the scheduling to quick public transport vehicle in prior art, therefore can only using minute as the minimum time of day of dispatching timetable, can not be accurate to second, so the nearest regular bus information of arriving at a station of issuing on the Information Points such as LED display is the estimated value of take minute as unit, can't realize releases news is accurate to second, makes troubles to passenger in a hurry.Moreover, the running status of the quick public transport vehicle that in prior art, the passenger can't the Real-time Obtaining current time, travel time that can't reasonable arrangement oneself.

Utilize the arrive at a station information issuing method of internet information delivery system of the above-mentioned bus rapid transit be accurate to second in the present embodiment, comprise the steps:

I. generate schedule plan

In practical implementation, whether the data acquisition that each driver's driving habits and driving experience can have influence in schedule plan is accurate, therefore the mode of choosing driver Shi Ke and taking everybody to elect, select the outstanding driver who generally acknowledges to obtain schedule plan, preferably the 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, also be provided with vehicle GPS positioning unit and vehicle-mounted odometer counting unit on quick public transport vehicle, utilize the vehicle GPS positioning unit to record the quick public transport vehicle position coordinates as the reference position coordinate, utilize vehicle-mounted odometer counting unit to record distance travelled as the benchmark mileage, be stored in schedule plan;

For convenient different bus rapid transit routes and the different websites distinguished, in the present embodiment, also be included as the step that every bus rapid transit route and each website thereof are numbered respectively; The described schedule plan of each obtaining in this step thus all has the identification number relevant to bus rapid transit route site number.When being numbered for the quick public transport Road, can adopt various ways, as long as different quick public transport Roads can be made a distinction, in the present embodiment, can different quick public transport Roads be numbered arabic numeral.

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

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

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

The schedule plan of No. 1 bus rapid transit route of table 1

The station of setting out: arrival station, the De Mao village: Dongying room

The schedule plan that No. 1002, table 2

The station of setting out: arrival station, Dongying room (102): six camp gates (103)

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

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

II. generating run timetable

Transfer and all schedule plans that the bus rapid transit route is relevant, according to the frequency of each order of classes or grades at school quick public transport vehicle of this route, down time of respectively stopping website, by the running time T in described schedule plan _iChange the corresponding local time into as benchmark constantly, form and show one group of time of running corresponding with each order of classes or grades at school quick public transport vehicle; By all described quick public transport vehicle terminals that the time of running, table sent to dispatching center's terminal and wait to dispatch a car;

If setting out of standing in the fast 1 bus Cong Demao village (101) of n order of classes or grades at school is 12:30:00 constantly, be that zero-time is answered corresponding 12:30:00, add the running time in schedule plan No. 1001, the corresponding local time in the time of can releasing quick public transport vehicle arrive any one reference position between two stations, according to watch 1 can obtain the n order of classes or grades at school fast 1 bus No. 1001 the times of running table as shown in table 3.

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

The station of setting out: arrival station, the De Mao village (101): Dongying room (102)

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

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

By table 3 and table 1 contrast, and table 4 is known with table 2 contrast, shows the described time of running running time in described schedule plan to be scaled to the corresponding local time, other Information invariabilities exactly.The like, can obtain all time of running table of quick public transport vehicle in operational process.

III. generate the route schematic diagram

The vehicle dispatching performance element arranged on the quick public transport vehicle that the scheduling unit at place, dispatching center and wait are dispatched a car according to the reference position, benchmark mileage and the benchmark that record in table the described time of running constantly, adopt and mean that intention means the quick public transport vehicle travel route time of running, wherein with reference position point, mean the benchmark moment that record in table the described time of running, the line segment that connects described reference position point composition means travel route;

IV. generate schedule information

S1, judge whether current time T equals the zero-time of record in a certain time of running of table; If equal, assign out and send instructions to corresponding quick public transport vehicle immediately; Otherwise, judge whether current time T is greater than the zero-time of a certain time of running of table record, be less than the time of arrival of described time of running of table record simultaneously;

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

For example, when current time T is 12:35:34, the current actual position coordinate (x of quick public transport vehicle detected _D, y _D), described relatively judge module 34 is by the current actual position coordinate (x of quick public transport vehicle _D, y _D) with time of running table in reference position compare 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 corresponding to this position _DFor 12:35:31; Simultaneously, 12:35:31 and corresponding benchmark mileage afterwards thereof in showing the time of running, deduct benchmark mileage number 5.00 corresponding to 12:35:31 constantly successively;

The time of running, table will be deformed into:

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

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

Adopt this method can eliminate the cumulative errors of far bringing due to operating range, as common practise, can know, for the metering of Vehicle-Miles of Travel, be that the number of turns that turns over according to wheel and the diameter of wheel obtain, and the technician is difficult to guarantee that the diameter of wheel always remains on identical numerical value, therefore the driver drives the mileage number recorded in the quick public transport vehicle driving process in advance, the mileage number recorded during with actual travel, very likely not identical, because the diameter of wheel is because variation has occurred the aeration quantity difference of tire, so can have cumulative errors after long distance travel, in the present embodiment owing in real time the mileage number zero clearing having been eliminated to this 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, read the now mileage number of mileage counting submodule 322 records, if now the mileage number of mileage counting submodule 322 records is 25.00m, with the benchmark mileage S in time of running table ₄Association, S ₄Corresponding benchmark is T constantly _DFor 12:35:34;

Selecting described deviation alarm threshold value C is 1s, thus, can calculate mistiming Cw=|T-T by comparing judge module _D| be 3 seconds, be greater than C, and T-T _DFor negative, so quick public transport vehicle lags behind 3 seconds;

The prompting driver will remain the reference position point and quick public transport vehicle current time physical location or T of the corresponding benchmark moment of actual travel mileage that current time T is corresponding _DCorresponding reference position point is in coincidence status;

Figure 4 shows that corresponding reference position point and the corresponding reference position point T of quick public transport vehicle current time physical location of current time that described deviation display module 35 shows _DSchematic diagram; The time that current time T is corresponding as shown in the figure is 08:00:11, and time corresponding to TD in the benchmark moment corresponding to the current physical location of quick public transport vehicle is 08:00:14, and obviously quick public transport vehicle travels leading 3 seconds.In the present embodiment, the reference position point that described deviation display module 35 shows is 9, and by current time corresponding Dian Yu centre position, reference position, in the quick public transport vehicle operational process, As time goes on, the moment of reference position point representative also passes backward.And, in actual moving process, can show more reference position point.When quick public transport vehicle is leading or surpass the scope of said reference point retardation time, can directly adopt digital prompt, for example, shown in Fig. 4, when quick public transport vehicle in the time of leading 13 seconds, can not be prompted to the driver by the point of the reference position shown in Fig. 4, now described deviation display module 34 can directly be prompted to the driver by deviation, as " leading 13 seconds ".

In dispatching center's terminal, be illustrated in figure 5 a kind of form of expression, in Fig. 5, adopt "●" to mean benchmark corresponding to the current physical location of quick public transport vehicle corresponding reference position point constantly, adopt

mean reference position point corresponding to current time, quick public transport vehicle for different order of classes or grades at school can adopt different color differentiatings, because the picture that this figure is black and white can not be according to color differentiating, therefore the order of classes or grades at school that adopted numerical reference in corresponding symbol top: as " B3 " means the 3rd order of classes or grades at school, " R12 " means the 12nd order of classes or grades at school, " G18 " means the 18th order of classes or grades at school, " Y19 " means the 19th order of classes or grades at school, but during actual motion, can utilize different colours to mean the vehicle of different order of classes or grades at school, for example adopt blue the 3rd order of classes or grades at school that means, adopt red the 12nd order of classes or grades at school that means, adopt green the 18th order of classes or grades at school that means, adopt yellow the 19th order of classes or grades at school etc. that means, as the mode that can realize, quick public transport vehicle for different order of classes or grades at school can take different shapes to mean, for example the 3rd order of classes or grades at school can adopt triangle to mean, the 12nd order of classes or grades at school can adopt rectangle to mean, the 18th order of classes or grades at school can adopt rhombus to mean, the 19th order of classes or grades at school can adopt the pentagram shape to mean etc.

The dispatcher can exercise supervision to the situation of scheduling in dispatching center, as can be seen from the figure dispatches and whether is accurate to second.Take Fig. 5 as example describes, 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 of showing the time of running.And for the 18th order of classes or grades at school quick public transport vehicle, the super the first two of benchmark corresponding reference position point of the moment corresponding to the current physical location of quick public transport vehicle or distance travelled put the reference position point corresponding in current time, therefore belong in advance and travel, and leading two seconds; For the 12nd order of classes or grades at school quick public transport vehicle, four reference position points that point is corresponding in current time of the constantly corresponding reference position point hysteresis of benchmark that the current physical location of quick public transport vehicle or distance travelled are corresponding, therefore belonging to lags behind travels, and lags behind for four seconds.

Generally the driver can revise voluntarily according to above-mentioned prompting, if because certain reason is not revised, the dispatcher can be to not having the driver according to the quick public transport vehicle of showing the time of running to travel to send schedule information, also can adopt the form drivers such as phone, note, thereby further guarantee the degree of accuracy of scheduling.
