Embodiment
Before forwarding the detailed description referring to figs. 2 to 13 to, first will set forth some general aspect based on Fig. 1.
The means of transport that is ranked that relate generally to of the present invention is advanced regularly according to special time table.This type of means of transport that is ranked can be such as train (such as international, at a high speed, country, area or commuter train), motorbus, shuttle, aircraft, ship or ferryboat, tramcar or any other common carriage.
Timetable is usually created by the operator of means of transport and is issued.Such as, SCNT creates and issues the timetable of all TGV being used for running in France, and Deutsche Bahn generates and be distributed on the timetable of the ICE of Germany's operation.Operator make timetable via the Internet or means of transport be originally in/in can be used for the public and particularly the passenger at website place.The timetable of means of transport indicates the starting point of means of transport and final destination and through-station usually.In addition, the departure time at its time of arrival usually indicating the departure time at inception point place and final purpose to be located in and through-station place and time of arrival alternatively.
Thus, the timetable of operator is logically by the means of transport that will the be ranked grouping about the route of the means of transport that is ranked and traveling time thereof.Hereinafter the means of transport walking same routes in the identical time is called the means of transport belonging to specific " through transport ".Such as, this type of through transport is formed at all trains that 10 o'clock advanced from Nice to Paris every day.On the other hand, term " route " refers to the means of transport that is ranked according to the path of timetable from inception point to final destination.Such as, when belonging to train (i.e. the TGV of 10 o'clock of every day from Nice to Paris) of above-mentioned through transport, route is given by the rail track between Nice and Paris.In addition, usually, the route of means of transport of being ranked is made up of multiple section.Hereinafter, term " section " refers to a part for the route between two follow-up websites listing in timetable.Exceptionally, if timetable does not specify any intermediate stop between originating station and final destination, then route is made up of an only section.But, usually, route is divided into multiple section.If six through-stations such as between timetable instruction starting point and final destination, then this route is subdivided into seven sections.
Usually, passenger not only the plan of the means of transport of the Day Settings by operator is arrived and the departure time interested, and its intention is used or actual development of its current particular vehicle used interested.Such as, minimize to make the stand-by period or select suitable through transport means of transport, make passenger know its means of transport current be ideally punctual, lag behind dispatch list or be even useful before dispatch list.In this respect, term " delay " is here used for containing these whole three possibilities.Therefore, when means of transport lags behind dispatch list, delay is positive, and may by next website of arrival later indicated by timetable.When means of transport is punctual, it is zero, and may be arrived next website the time indicated by timetable.If means of transport is before dispatch list, then it is for negative, and therefore may arrive next website than more Zao indicated by timetable.
In order to solve this needs, there will be a known the subscriber equipment being suitable for the current delay calculating means of transport in the prior art.Example is the JP 06044495A mentioned above.But disclosed Delay computing requires the manual input of destination information and providing of user's current location, such as, by utilizing GPS (GPS) wherein.Therefore, when have bad or do not exist GPS cover, this system can not suitably work.In addition, the method described by JP 06044495A be based on the time of arrival that will be ranked simply with current time and by destination locations compared with current location.Obviously, the linear travel of user's vehicles is supposed.This and usual nonlinear reality are advanced and uncorrelated.Therefore, inaccurate inherently by the method for JP 06044495A.
The object of the invention is those problems solving prior art.The deferred message method/system that here proposes allows to not rigging position determination function or is in the subscriber equipment that wherein can not carry out the situation that position is determined and provides real time delay information.In addition, it is intended to the accuracy improving deferred message.
On the other hand, this delay is determined based on more more detailed than the timetable issued by means of transport operator with reference to dispatch list 4.As previously mentioned, those operator's timetables only comprise the object time of station about means of transport or website.But, think that this information is inadequate at present, because it is not provided for any reference information of the position of (that is, in section) between through-station.A possibility of supplementing operator's timetable is the linear travel of hypothesis means of transport between through-station, and therefore carrys out " filling " timetable with linear interpolation.But at present, introduce in detail with reference to dispatch list 4, it is intended to reflect more accurately that the reality of the reality of means of transport therebetween between website is according to plan advanced.For this reason, except the target time information of the through-station that can obtain from each operator timetable, the target time information for any optional position along route is also comprised with reference to dispatch list 4 in detail.In other words, not only indicate arrival and the departure time of the website specified by operator in detail with reference to dispatch list 4, and comprise the additional belt timestamp reference position of punctual means of transport especially, this position is arbitrary, namely has nothing to do with station or website.According in the deployment system of the delay determination operation proposed, the detailed reference schedule table data for each through transport being determined by this delay to cover will be there is here.Such as, again with reference to aforementioned TGV example, by exist be used for 10 o'clock from Nice from Nice to Paris every day TGV detailed with reference to schedule table data and be used at noon from Nice from Nice to Paris every day TGV further in detail with reference to schedule table data.Exist and set up this type of in detail with reference to multiple possibilities of dispatch list 4, will be further described below.A possibility is so-called " social scheme ", according to the program, collects the data from the location-based request about punctual means of transport.With only use be ranked station as with reference to data based on timetable scheme compared with, this in detail allows due to the reference data granularity increased the delay determining means of transport more accurately with reference to dispatch list 4.
On the other hand, this delay defining method utilizes log book 5, wherein have collected about the real time delay information just in question means of transport.With being postponed by the position-based performed as follows to determine that the real time delay information generated fills log book 5 (visual by the left branch of Fig. 1).
The passenger being positioned at maybe this place on means of transport is equipped with mobile subscriber equipment 1, such as mobile phone, smart phone, laptop computer, flat computer etc.Subscriber equipment 1 generates the request of the real time delay for means of transport.This request at least comprises the current location of the subscriber equipment 1 identical with the current location of means of transport.It is distributed to server, or is alternatively used cache mechanism locally to process (this will explain below in more detail) at subscriber equipment 1 place.This request then serviced device or received by subscriber equipment 1 in inside.Next, this request is processed to calculate the delay of means of transport.Based on the current location indicated in this request and the timestamp be associated with this request in addition, consulting in detail with reference to dispatch list 4, and uses each band timestamp reference position about punctual means of transport to calculate the real time delay (square frame 12 place in FIG) of means of transport.Further describe the details of Delay computing below.Square frame 8 place in the drawings, the deferred message (again, by server or inner at subscriber equipment 1) that result obtains is returned to subscriber equipment 1.But in addition, the deferred message of calculating is recorded and is stored in log book 5.
Be filled and determine that the log book 5 of deferred message obtained promotes purely time-basedly to determine (describing in the right branch of Fig. 1) by location-based, it works when any position of not undertaken by subscriber equipment 1 is determined.Subscriber equipment 1-it can be issue the same of location-based request or another subscriber equipment-generate time-based request in advance, and contrary with above-mentioned location-based request, it does not comprise the instruction of the current location of subscriber equipment 1.Its reason can be that equipment 1 can not determine its current location, because itself and unassembled any position determining means, it is only equipped with the inaccurate position determining means being not enough to determine for this delay, or position can not be carried out determine when there being request, such as owing to lacking covering, lack the free sight line of satellite, away from means of transport (such as user interested) at home etc.Suppose to determine based on this time-based request the log book data that are associated with the means of transport of user, the delay (square frame 7 as in FIG) of means of transport can be determined, and the deferred message (again at square frame 8 place of Fig. 1) returned about means of transport based on real time delay entry available in log book 5.
Like this, the subscriber equipment 1 of passenger shows the real time delay information about means of transport.This real time delay information can comprise such as according to operator's timetable means of transport at website, particularly the current time of time of arrival that is ranked at next website (end points of current road segment) place, means of transport postpones and arrives in each potential reality that next and/or final purpose are located in.
As mentioned above, position association requests and time correlation request are both associated with timestamp.This timestamp is used for determining that means of transport is considered to section at this place and for the calculating of real time delay at request time.There are two modes substantially in order to rise time stamp.A possibility is directly included in the request of subscriber equipment 1.Therefore, according to this option, in fact this request comprises timestamp.Another possibility be only when receiving request the rise time stamp.If by this request of server central process (by it locally at subscriber equipment 1 everywhere managing contrary with using the cache mechanism further described below), then this option is useful especially.Consistent time management is guaranteed, because all requests are all added timestamp by same server side clock at server place rise time stamp.When use first option (comprising timestamp in the request), if namely subscriber equipment 1 is synchronous with trusted clock, then also can realize similar consistent time management.
As indicated above, have how to set up detailed reference dispatch list 4 and the multiple options creating the required arbitrary band timestamp reference position of means of transport.Explain above as initial, these band timestamp reference positions are " arbitrarily " because it refers to any position on route, with the website of means of transport or station irrelevant.Setting up is in detail so-called " social schemes " with reference to a possibility of dispatch list 4, and it is irrelevant with the cooperation of means of transport operator.Therefore, it can be carried in the prestige that need not depend on operator when the detailed data about the network of its means of transport and timing condition and adopt.This social scheme utilizes the location-based request of reality sent by the subscriber equipment 1 be positioned on means of transport.Because each in these requests provides the position of means of transport and stamp correlation time (i.e. timestamp+position to), it usually provides valuable database.Because the entry in detail with reference to dispatch list 4 serves as reference tape timestamp position, perform the confirmation of collected data.The sum right according to collected timestamp+position, find belong to punctual means of transport those to (namely according to the means of transport that the timetable of operator advances), and abandon the remainder data group from unpunctual means of transport.Can by checking that the timestamp+position of the position had near the website that operator for it has set the reference time is selected performing this.If have the position near this website to corresponding to by the timetable official hour of operator, then think that each means of transport is punctual, and think that all timestamp+positions that from then on means of transport collects are to being effective, and be included in detail with reference in dispatch list 4.
Set up and be in detail manual request, the simulation of each data undertaken by the operator of means of transport that can be generated by the specialized work personnel on means of transport with reference to other optional replacements of dispatch list 4 or provide.
Log book 5 (square frame 7 in Fig. 1) is utilized in response to not indicating the request of the current location of means of transport in two modes substantially.A mode is the nearest real time delay entry about means of transport returned to request subscriber equipment 1 simply in log book 5.If this nearest entry in log book 5 is up-to-date, and therefore reflects this real time delay of means of transport exactly, then this option is suitable especially.Such as by the timestamp of log book entries and with the up-to-date property comparing last entry determined in log book 5 of asking the timestamp be associated.If the difference between these two timestamps is below given threshold value, such as, lower than 5 or 10 minutes, or it is still in the current road segment of means of transport, then suppose the correctness of last log book entries, and returns the deferred message of this nearest log book entries.The another way of log book 5 is utilized to be extrapolate to log book entries to evaluate the trend postponed to the request of the position not indicating current transportation instrument.If nearest log book entries be quite old (such as, difference between the timestamp of last entry and this request is greater than aforementioned given threshold value), therefore it is out-of-date by inference and may reflect the actual real time delay of means of transport exactly, then may think that extrapolation is suitable.The extrapolation technique that can suitably apply is index smoothing.The result of extrapolation is returned to subscriber equipment 1.
Similarly, there are the various options being used for carrying out real time delay calculating (square frame 12 in Fig. 1) in response to the request of the current location of instruction means of transport.Such as, if comprise the band timestamp reference position corresponding with the current location of the means of transport indicated in the request with reference to dispatch list 4 in detail, then calculate the difference of stabbing between the timestamp be associated with this request with the reference time be associated with reference to this position in dispatch list 4 in detail just enough.This difference between two timestamps is the accurate real time delay of means of transport, and is returned to subscriber equipment 1 (square frame 8 place in FIG).If this does not comprise the reference position corresponding with the position indicated in the request with reference to dispatch list 4 in detail on the other hand, then there are two other options.Or, in the detailed reference position with reference to searching in dispatch list 4 closest to the position indicated in the request, and the difference of as previously mentioned, namely being stabbed between the timestamp be associated with this request by the reference time calculated be associated with reference to this position in dispatch list 4 in detail calculates real time delay, calculates real time delay.But this introduces certain inaccuracy, it becomes more obvious when two positions (namely in detail with reference to the position in the position in dispatch list 4 and request) are departed from larger mutually.Alternatively, in order to make this inaccuracy minimize, the detailed linear interpolation technique with reference to the band timestamp position in dispatch list 4 near relative to position indicated in the request can be adopted.
Outline briefly above and will there is the detailed reference schedule table data of each through transport and the means of transport being used for being capped.Therefore, correct means of transport or each through transport and corresponding detailed in schedule table data must be derived from the request of subscriber equipment.This option associated between means of transport/through transport/detailed reference schedule table data is asked to be the authentication code that the permission comprised in the request identifies means of transport for realizing.Then the related data in correct timetable data, current road segment (by using the geographic position comprised in the request) and detailed reference dispatch list 4 can be inferred.In an embodiment example, this authentication code is passenger name record (PNR) identifier, and it allows the route information of inquiring about passenger in PNR database.This route information can comprise the information of the through transport of the means of transport about the current use of passenger.Alternatively, the authentication code except PNR identifier is comprised in the request.Such as, subscriber equipment 1 can point out user to input his/her the current means of transport that using and through transport respectively, and then passenger manually inputs this information then comprised in the request.
In alternate embodiments, location-based determine to comprise be cached at request subscriber equipment 1 place with detailed reference to dispatch list 4.Such as, its first location-based solicited guidance about particular vehicle is determined server to delay by subscriber equipment.Server keeps in detail with reference to dispatch list 4, the data that its through transport comprising the means of transport that using current with passenger is associated.The location-based request of subscriber equipment 1 is delayed by determines that server processes as described above, and the real time delay calculated is returned to subscriber equipment 1.But, in the Alternate embodiments using high-speed cache, what belong to the current transportation instrument of passenger is also transferred to subscriber equipment 1 in detail with reference to dispatch list, together with real time delay information or to be returned before or after real time delay information in single message by server.Then be buffered in detailed reference to schedule table data in the cache memory at subscriber equipment 1 place.Therefore, locally can process the follow-up location-based request that same subscriber equipment 1 carries out at subscriber equipment 1 place, and not need that location-based request is transmitted into delay and determine server.Like this, can location-based Delay computing be carried out, and not need subscriber equipment 1 to activate any external communication link, and therefore can such as perform in the region not having radio to cover.
If use the detailed reference dispatch list 4 of high-speed cache locally to perform location-based delay at subscriber equipment 1 place to determine because subscriber equipment 1 lacks radio link, then therefore can not be stored in log book 5 by the real time delay information of local computing, it can remain on delay and determine in server.If like this, then the deferred message of local computing also will be locally buffered in subscriber equipment 1 place, in local log book.When radio link is again when time point is after a while available, the real time delay information transmitting of buffer memory is got back to delay and is determined server by subscriber equipment 1, and then information is attached in (central authorities, server side) log book 5.
The detailed in schedule table data of the current means of transport used of passenger is not limited at the high-speed cache at subscriber equipment 1 place.On the contrary, other information can usefully be extended to.Such as, also other detailed reference schedule table data that may be relevant to the following means of transport (such as through transport means of transport) that passenger may will use can be cached at subscriber equipment 1 place.If in view of subscriber equipment 1 place available buffer space and can be used for the communication link bandwidth of subscriber equipment 1 and feasible, future may be become relevant with passenger even more or all detailed be transferred to subscriber equipment 1 with reference to schedule table data and be stored in there postpone to determine for local position-based.In addition, in response to the first location-based request of subscriber equipment 1, also server side log book 5 can be transferred to subscriber equipment 1 high-speed cache there.Although this high-speed cache log book becomes out-of-date when the long period, section did not upgrade and therefore so unimportant, it makes it possible to locally perform time-based determination at subscriber equipment 1 place and do not need query latency determination server.Weigh between the resource that can be used for subscriber equipment (such as the quality of free buffer space, communication link) and the potential improvement that can be realized by cached data in the degree of subscriber equipment place cached data.
The basic skills of above-outlined can being used for other application, namely asking and result of calculation and fill log book 5 by real time delay information by collecting location-based delays.Such as, can by the display of the message transport kept by log book 5 to website, the website via network-accessible or network service, be similar to the Push Service of RSS or SMS or any other is similar to the distribution of information channel of broadcast.Therefore, do not travel on each means of transport other people can benefit from this real time delay and determine mechanism, have nothing to do with its current location.
In addition, for real time delay system and log book 5 are fed to not necessarily for obtaining about the message of the information of the real time delay of means of transport in the scope of method in this paper.On the contrary, this type of message can purely for apprizing system about the object of information of current delay of in fact not asking the means of transport postponed.Such as, be similar to website personnel, the people of reality or potential station wagon or other interested people and so on such as by using GSM SMS determine server transmission message to delays, and thus can indicate the position of particular vehicle and current delay.In response to this type of message, postpone to determine that server performs the checking of information, and if discovery information may be effective, then add delay instruction to log book 5.
Forward more detailed description to now, Fig. 2 shows the more specifically example that this real time delay is determined.Be similar to Fig. 1, the left hand branch of Fig. 2 shows location-based delay and determines, and mentions that time-based delay is determined in the branch on right side.
In the figure 2 example, subscriber equipment 1 is equipped with the smart phone being arranged to generate this locality installation postponing to determine to ask and postponing to determine application program.Be arranged to show information and user wishes that initiating this delay determines, allows the graphical user interface that user inputs to user if it has.It also provides the mobile communication interface by means of 2G, 3G and/or 4G transceiver and/or multiple transceiver, and it operates according to other mobile communication standards of such as WiFi IEEE 802.11 and so on.These communication interfaces promote mobile communication, particularly postpone the reception determining transmitting and the real time delay information of asking.
In addition, it is equipped with GPS transceiver, and therefore, it is possible to determine its position, condition is the communication link that can be established to gps satellite.If GPS is unavailable for a certain reason, then smart phone 1 can adopt other location determining method, such as triangulation or observed time difference technology.If can carry out position to determine, then smart phone 1 is initiated location-based delay and is determined after each input command from user.It determines its position and geographic position result obtained comprises in the request.In addition, the timestamp of instruction current time is comprised in the request generated by smart phone 1.Alternatively, as explained above, timestamp not included in request, but only obtains at server side due to the conforming reason of overall time.Finally, PNR mark is comprised in the request.Or prompting user is inputted, or it is automatically generated when smart phone 1 place locally can use in each information.When smart phone 1 has completed the establishment of location-based request, it is transmitted into delay by mobile communication link and is determined server 47 (not shown server in fig. 2 will describe the high level architecture of total system below with further reference to Figure 10).
When being received this request by server, utilize the geographic position that comprises in the request and PNR mark determine user be currently located at means of transport (more rightly, the through transport of means of transport) above it and more specifically means of transport be currently located at the current road segment of the route above it.Therefore, postpone to determine that server 47 is suitable for being coupled to the travel information system of such as PNR database 2 and so on.Schematically showing of PNR database 2 is provided by Fig. 3.It comprises the route information of user's travelling.This travelling can be formed by multiple sections, the flight such as from A to B and the travelling of the connexion from B to C.One in this section is formed by current transportation instrument, and user is located thereon face and postpones to determine that request is associated., mention this example of the rail travel from B to C for illustrative reason below, but this example should not introduce any restriction relative to means of transport type.For finding this object of means of transport asking to relate to, each identification information remained in PNR database 2 is most interested, i.e. the user ID (with reference to figure 3) of train that should take for his/her travelling from B to C according to route.
After grasping train ID (such as: " Tr1 "), can with reference to the orthochronous table 3 of train operator that also can be used for server 47.The example of timetable 3 is provided by Fig. 4.This timetable can comprise multiple parameter, wherein by the geographic position of TrainID, StationID (" stID "), website, (" lat " represents latitude, " lng " represents longitude, indicates in units of spending) and arrive and the departure time (" ArrTD ", " DepTD ").Therefore, according to the very simple example of Fig. 4, the inception point of train Tr1 is the St1 being positioned at 43.55 degree of lat and 7.02 degree lng.Train should leave therefrom at 7:30.The next stop is through-station St2, and it is positioned at 43.59 degree of lat and 7.12 degree lng place.Train should get there at 7:38 after eight minutes, and left at 7:40 after two minutes in stop.Final destination is the website St3 being positioned at 43.70 degree of lat and 7.28 degree lng place, and it should arrive at 08:01.In addition, timetable 3 can comprise the range information between the geographical location information of website and website, i.e. the length (not shown in the diagram) in section.The object of query time table 3 determines that means of transport is currently located at the section (in other words: next the plan station according to the timetable 3 of operator) at this place.Therefore, the geographic position comprised in the request is delivered to timetable 3 as the argument of inquiring about, and fetches current road segment.Therefore, this process geographic position (comprising at first in the request), timestamp (comprise in the request or set when being received request by server) and section (determining according to the consulting of the timetable 3 just described and PNR database 2) move on further.
Next step is in detail with reference to the renewal (square frame 10 in Fig. 2) of dispatch list 4.As described in detail, in detail comprise arbitrary band timestamp reference position with reference to dispatch list above, namely for the timestamp+position pair of the punctual means of transport of the timetable 3 according to operator.Provided in detail with reference to the example of dispatch list 4 by Fig. 5.It comprises trainID (such as Tr1, Tr2), legID, timestamp and position (lat, lng).According to the example of Fig. 5, train Tr1 should be in coordinate 43.56 degree of lat, 7.11 degree of lng, be in 43.57 degree of lat, 7.11 degree of lng etc. at 07:36 at 7:35.This set of arbitrary band timestamp reference position forms the curve movement (with reference to figure 7) of means of transport, and its confirmation data comprised are more much more accurate.
As mentioned above, setting up the detailed scheme with reference to dispatch list table 4 of also enrichment is so-called " social scheme ": collect the location-based user in fact occurred and ask and be stored in this form.Upgrade 10 and just in time serve this object with reference to the step of dispatch list table 4 in detail.It is usually optional, because if there are enough valid data in detail with reference to dispatch list table 4, does not then need it.Upgrade 10 to mean in detail adding paired geographic position and timestamp as with reference to the date with reference to dispatch list table.But, if perform this optional interpolation, then perform further process subsequently, namely confirm 11.The band timestamp reference position of adding needs to be identified to guarantee that it is suitable for serving as reference position really.Its only have be only when namely means of transport (in this example train Tr1) is in fact punctual suitable.As explained above, the whether punctual determination of specific T r1 can be carried out by making to add to mate with the reference data of timetable 3 with reference to any band timestamp position of dispatch list table in detail.As long as not yet perform confirmation, then indicate that the analog value in " effectively " is configured to "No" (with reference to figure 5).If find that the entry be not yet identified is effective, then the value that " effectively " indicates is modified as "Yes".If find that it is invalid (namely train is unpunctual), then it is deleted from detailed with reference to dispatch list table 4.
This location-based delay is determined then to continue to (square frame 12 of Fig. 2) based on this in detail with reference to the delay actual computation of the confirmation entry of the timestamp reference position of dispatch list table table 4.For the geographic position stemming from the request that smart phone 1 carries out in detail with reference to the test of dispatch list table 4.If comprise the reference position of accurately mating with the geographic position of request in detail with reference to dispatch list table 4, then in this case, can take out with reference to dispatch list table 4 from detailed with reference to the time simply.Otherwise, by directly carrying out linear interpolation to calculate the reference time for this geographic position to the time be associated with the reference position in detailed reference dispatch list table 4 before and after the geographic position from request.Do not get rid of and only comprise relative to the considerably less band timestamp reference position of current road segment or the entry at all not except station/website with reference to dispatch list 4 in detail yet.In the commitment of the deployment determined in this delay or after bottom timetable changes (it occurs on train time schedule for such as annual twice), situation may be especially true.In this case, will at least comprise the data that can obtain from the timetable of operator with reference to dispatch list 4 in detail, and carry out computing relay by carrying out linear interpolation to time and geographic position instruction.
Provide example by Fig. 6, its hypothesis only comprises the reference time about starting station St1 (setting out at 7:30) and final destination St3 (arriving at 08:01) with reference to dispatch list 4 in detail.The distance (with reference to figure 4) between two websites is there is in timetable, or by using following equation to estimate according to the geographic position of website:
Distance(St1,St3)＝arcos(cos(lat_St1-lat_St3)cos(lng_St1)cos(lng_St3)+sin(lng_St1)sin(lng_St3))
[note: independent variable that is sinusoidal and cosine expression formula provides in units of radian.】
Distance in km＝Distance(St1,St3)*6372,795477598
Next website in current geographic position indicated by calculating in an identical manner in the location-based request received from subscriber equipment 1 and in detail reference dispatch list 4 or the distance between reference position.Then, by using following three rules to perform linear interpolation:
Tp＝TI*Dp/DI
Wherein, Tp takes the linear travel of means of transport to arrive time needed for next reference position, TI completes from previous to the reference time needed for the travelling of next reference position by means of transport, Dp is the distance between current location and next reference position, and DI is the distance (the particular exemplary numeral with reference to being provided by Fig. 6) between two reference positions.Therefore, in the example of fig. 6, train Tr1 divides 25 seconds (08:01-17 point 35 seconds) should be positioned at 43.65 degree of indicated in the request lat at 7:42; The reference position of 7.15 degree of lng, it is according to the geographic position that indicates in the request and is included in detail with reference to the reference time of examining the data in dispatch list 4 and calculating.
Difference between the reference time calculated and the timestamp be associated with request, it is the expectation real time delay of train Tr1.
The example of the Delay computing 12 according to location-based request is provided with reference to figure 7.Fig. 7 describes the reference curve movement by the train Tr1 specified with reference to dispatch list table 4 in detail.The X-axis of figure describes position, Y-axis describes the time.As mentioned above, this curve movement be such as by collect be included in timestamp+position in the location-based request relevant with the means of transport of punctual same through transport to and establish.Generate and also collecting more entries with reference in dispatch list 4 in detail, curve movement general is more accurate and complete.By using this curve movement, determine that the reference time of train Tr1 is as input parameter with the geographic position comprised in the request.Such as, according to curve movement, the geographic position of 43.65 degree of lat, 7.25 degree of lng corresponds to the reference time of 7:52.Then by this reference time with compared with asking the real time of the timestamp be associated.If this timestamp is read as 8:12, then real time delay is 20 minutes.
Referring back to Fig. 2, location-based delay deterministic process proceeds, Update log book table 5 (square frame 13).As explained above, the object of log book table 5 makes real time delay Information Availability in the passenger that can not provide positional information together with its request.The example of log book table 5 is provided by Fig. 8.It comprises trainID (such as Tr1, Tr2), from reference information (such as " planTime ") and the timetable (starting station [" stDep "], next arrival station [" stArr "], plan departure time [" planDep "] and plan time of arrival [" planArr "]) in detail with reference to dispatch list table 4.Especially, it comprises from request and the real-time information of Delay computing, the geographic position namely indicated in the request (" lat, lng "), the timestamp (" realTime ") be associated with request, postpone and the supposition at next stop place arrive (" delay ", " realArr "),
Finally, via mobile communication interface by such as next arrival station and real time delay value and so on ask real time delay information transmission to get back to smart phone 1 (step 8 in Fig. 2).Then the client software be arranged on smart phone 1 shows information to passenger.
Return now the time-based delay described on the right side of Fig. 2 to determine, smart phone 1 at gps signal too weak or do not have at all GPS link can with generate time-based request when not having its current location to indicate.Therefore, this time-based request only comprises timestamp (it also may alternatively only add at server side) and PNR mark.Request is transmitted into server 47.Consult PNR database 2 and timetable 3 to determine trainID, as previous about location-based determine as described in.After determining trainID like this, carry out inquiry log book table 5 by using trainID to find the potential existing real time delay information being postponed to determine generation by previous position-based.Such as, if determine that log book table 5 comprises the entry of the current road segment of the train for passenger, then obtain the delay be associated with this entry.
In the example of fig. 8, suppose on train Tr1 its second section between website St2 and St3.According to timetable, it should to set out at website St2 place at 7:40 and arrive St3 (also with reference to Figure 4 and 5) at 8:01.Along this travelling, occur and processed two location-based requests, and the real time delay of calculating being stored in log book table 5.First location-based request occurs at 7:46, and on Tr1 its first section still between St1 and St2.The delay of 10 minutes detected.After a while, along with Tr1 has been advanced to its second section between St2 and St3, receive another location-based request at 8:12 and determine the delay of the further increase of 20 minutes.Present hypothesis receives time-based request at 8:15 from server 47, consults log book table 5, and find it the only 8:12 entry of the current road segment about train Tr1 of early three minutes.Determine the length of delay of this entry, i.e. the delay (square frame 7 in Fig. 2) of 20 minutes.Then this delay and such as next arrival station St3 are turned back to the smart phone 1 showing information to passenger.
Below, discuss with reference to the process flow diagram of Fig. 9 a, 9b and 9c the embodiment example that the position-based of the caching function comprising above-outlined and time-based delay determine in more detail.Fig. 9 a describes the process that proceeds at subscriber equipment 1 place until issuing for till postponing the request determined.Fig. 9 b shows the process of the request at server 47 place.Finally, after returned delay determination result by server 47, Fig. 9 c is again visual by action in the side of subscriber equipment 1.
Usually, can according to following condition by related data traffic classification:
I () position determines that function and mobile communication function all can be used at subscriber equipment 1 place.
(ii) position determines that function can be used.But mobile communication link is disabled.
(iii) position determines that function is unrealized or temporarily unavailable.
But mobile communication link is available.
(iv) position determines that function and mobile communication link both can be used.
Data stream in situation (i) (position determines that function and mobile communication function all can be used) is as follows:
After 19 places start, process is from the validity check 20 that PNR identifies, and it is present in subscriber equipment 1 or is manually inputted by user.Then, after 21 places confirm the availability of mobile communication link for certain, subscriber equipment 1 is at 29 place's checking Caches.If Cache is empty, then utilize mobile communication link so that the detailed reference schedule table data downloaded about the means of transport referenced by PNR mark and current deferred message.For this purpose, at 30 places, Cache updating message is transmitted into server 47.In response to Cache updating message, server 47 is inquired about its database (i.e. PNR database 2, timetable 3, in detail reference dispatch list 4 and log book 5) and is returned corresponding data to subscriber equipment 1.These data are stored in its Cache by subscriber equipment 1.Then Cache comprises such as about the schedule information of current transportation instrument, particularly next arrival station, the detailed nearest train delays information with reference to schedule table data and current transportation instrument available in log book 5 for current transportation instrument.These information will enough be used for the real time delay calculating or estimate current transportation instrument when function and/or mobile communication link are not determined in location.
Further, in 27 place's positive result, subscriber equipment 1 checks whether gps signal can be used.Then it generate location-based request at 28 places and be transmitted into server 47.At server side (Fig. 9 b), server 47 checks whether can use about the timetable 3 of the current means of transport used of passenger at 31 places.If situation is not like this, each schedule information can be fetched at 32 places by the operator of means of transport.In order to comprise these data as soon as possible, server 47 suitably has the communication link to operator and timetable database thereof.
After 33 places determine that the request received by subscriber equipment 1 comprises geographic position for certain, server 47 performs the confirmation (not shown in Fig. 9 b) comprising geographic position in the request alternatively.This function confirmed guarantees that the geographic position comprised in the request is consistent with the route of the train indicated by PNR.Confirm to perform this, the railway road line drawing in its geographic position is stated and be can be used for server 47.Then by the geographic position that indicates in this request compared with the geo-location reference of route.If the geographic position of request is confirmed as " in route ", namely it corresponds to or at least approximate position corresponded on route, then think that the geographic position of request is effective.Can obtain the geo-location reference information of route from means of transport operator (outside Map Services), it is estimated by the operator of server 47 and/or is collected by a large amount of location-based requests received and inferred from it.In addition, by making the geographic position of request and timestamp pair indicate on route or close to route but substantially away from the request (such as being generated by the following passenger waited at follow-up website or the previous passenger that leaves train at last website place) in the geographic position of the physical location of train with being included in aim to filter out with reference to the information in dispatch list 4 and/or log book 5 in detail.If such as log book 5 comprises (such as still can process this type of out-of-date request based on log book 5 for the entry further along the geographic position of route, and such as can return the nearest real time delay be included in log book 5), then can filter out the request in the geographic position that instruction train has passed through.As another example, by considering the entry that also can filter out log book 5, the following geographic position (similarly, in response to this type of request, still can return nearest real time delay information) that request instruction train can not arrive.Usually, if the geographic position indicated by request is confirmed as haveing nothing to do with the current location of train, then can processes this type of similarly with time-based request and ask, namely think that geographic position does not exist, and by utilizing log book 5 to return real-time information.
After this optional confirmation step, server 47 performs location-based delay and determines (illustrating on the right side of Fig. 9 b).As explained in detail with reference to figure 2 above, this process comprises:
-determine current road segment at 41 places by using the geographic position be included in the request of subscriber equipment to carry out query time table 3;
-use section and geographic position to inquire about in detail with reference to dispatch list 4 at 42 places, and if be suitable for, interpolation is carried out to the band timestamp reference position remained in detailed reference dispatch list 4;
-calculate real time delay and the corresponding Estimated Time of Arrival at next website place at 43 and 44 places; And
-at 45 places, with at least timestamp (" realTime "), the real time delay (" delay ") of calculating and the estimation actual time of arrival (" stArr ") at next website (" realArr ") place carry out Update log book 5.
Then, server 47 returns results the real time delay information obtained to subscriber equipment 1 at 40 places, the such as actual time of arrival of next arrival station, estimation and the real time delay of calculating.By after mobile communication link (Fig. 9 c) receives each message, subscriber equipment 1 upgrades its oneself Cache at 46 places by these information, and via its graphical user interface, this information is presented to user.This process stops at 48 places.
Situation (ii) (position determine function can with-mobile communication link is unavailable) in data stream as follows:
If determined the unavailable of mobile communication link at 21 places at first, then subscriber equipment 1 has checked whether can use about the cache information of the means of transport indicated by user at 22 places.If this is affirmative, then at 23 places, locally can carry out delay at subscriber equipment 1 place and determine.Suppose that cached data comprises means of transport detailed in schedule table data about user, generate location-based request and by subscriber equipment 1 with its when mobile communication link by the similar fashion that available, serviced device 47 processed in inter-process.Unique basic difference is when not having mobile communication link, as will be impossible at the Update log book 5 that 45 perform for subscriber equipment 1 by server.Therefore, related data is buffered in local log book so that (this activity is not shown in fig. 9 a) is for update server side log book 5 when again becoming available when mobile communication link after a while by subscriber equipment 1.Present to user by by subscriber equipment 1 at the deferred message of local computing at 24 places, and process terminates.
Data stream in situation (iii) (mobile communication link can with-position determines that function is unavailable) is as follows:
In this case, perform time-based delay to determine.This process subscriber equipment 1 place from as the step 19 above as described in reference data stream situation (i) to 21,29 and 30.At 27 places, subscriber equipment 1 determines that gps signal is unavailable.Then the existence of mobile communication link is again verified at 25 places.
If mobile communication link side by side disappears, then usually can locally carry out delay in step 22 and 23 places to determine, because Cache was updated before seizure 29 and 30, and required reference and log book data should locally exist in the cache.Because in present case, current location do not known by subscriber equipment 1, postpone so local to determine to correspond to as the time-based delay performed by server 47 determined (as subsequently with reference to as described in figure 9b), condition is log book data is available.Alternatively, if do not have log book data to be cached (such as, because there is not any location-based request of the current travel about means of transport in advance), then can show to user the reference data be included in timetable.In this branch, then this process stops at 24 places.
If at 25 places this again demonstration validation mobile communication link still to exist or available, then generate time-based request at 26 place's subscriber equipmenies 1.This request comprise PNR mark and current time timestamp (described above, its likely only after a while when server 47 receives request by server 47 to add timestamp).At server side (now again with reference to figure 9b), perform step 31 and 32 as previously mentioned.Show this request in the determination at 33 places and do not comprise geographic position, namely it is time-based request.Therefore, server 47 performs the visual time-based delay in the left side of Fig. 9 b and determines.
At 34 places, server 47 checks the means of transport whether existed in log book 5 indicated by PNR mark.If situation is not like this, then server is at least attempted fetching schedule information in step 35 and 37 places, and returns to such as next arrival station and the arrival that is ranked at 39 places to subscriber equipment 1.May comprise warning or remarks, emphasize this be only be ranked but not the actual time of arrival.Even if be included in the information that the is ranked inaccessible for a certain reason in timetable 3, also error message will be returned at 38 places to subscriber equipment 1.
If show that the real time delay information of the current transportation instrument about user is available in log book 5 in the test at 34 places, then perform time-based Delay computing at 36 places.By imposing restriction, realTime < time-stamp < realArr fetches about the entry in the log book 5 of the current road segment of means of transport.Parameter " realTime " and " realArr " are parts (with reference to figure 8) for log book entries." realTime " value corresponds to the timestamp being directed to the previous location-based request in the entry of log book 5." realArr " value refers to the actual arrival at next website being determined estimation by previous real time delay.Therefore, the log book entries with the value of " realTime " of the value less than or equal to the timestamp be associated with current time-based request comprises the result that previous delay is determined.The general means of transport with reference to user of log book entries with the value of " realArr " of the value being equal to or greater than the timestamp be associated with current time-based request is located thereon the current road segment in face.If but " realArr " is lower than the timestamp of request, then can suppose the last section of each entry reference, and means of transport has arrived next arrival station.This can be the delay indicated by this entry is no longer up-to-date instruction.
The mode calculating real time delay depends on number and the time value thereof of log book entries.Such as, if log book 5 comprises an entry of the current road segment with reference to means of transport, then fetch next arrival station (" stArr ") of this log book, Estimated Time of Arrival (" realArr ") and length of delay (" delay ") at 36 places, and turn back to subscriber equipment 1 at 40 places.If do not have log book entries to meet above condition (i.e. realTime < time-stamp < realArr) on the other hand, then can return error message at 38 places.Alternatively, can the information that is at least ranked (next arrival station, be ranked arrival) be fetched from timetable 3 and turn back to subscriber equipment 1.If log book 5 comprises multiple entry, but it only belongs to previous section (i.e. time-stamp>realArr), then can perform extrapolation to the length of delay of these older entries, and the length of delay that result obtains can be returned as guestimate.In this case, again, can add deferred message may inaccurate warning or remarks.Finally, this process turns back to subscriber equipment 1 (Fig. 9 c).Feasible if (if namely providing real time delay information by server 47), then subscriber equipment 1 upgrades its Cache at 46 places, and process stops at 48 places.
Finally, the data stream in situation (iv) (do not have position to determine and do not have mobile communication link to use) is as follows:
If determine the unavailable of mobile communication link at first at 21 place's subscriber equipmenies 1, then may can carry out local time-based delay and determine, if log book data were previously cached, or at least can to user's presentative time table data.In this case, its step 22 that can provide with reference to the reference case (ii) above and 23 description.If do not have log book and/or timetable data to use in the cache, and therefore the inspection at 22 places is unsuccessful, then this process stops at 24 places.
But, if mobile communication link is available at 21 places, then upgrade Cache at 29 and 30 places.If then discharging mobile communication link subsequently and determining not existing of link at 25 places, then time-based delay should be carried out at 22 and 23 places and determine.This time-based delay undertaken by server that before being similar to, reference case (iii) has described in detail is determined.In this case, this process similarly stops at 24 places.
Figure 10 presents the high-level overview of the possible framework for this delay certainty annuity.In this example, function is determined in the position that subscriber equipment 1 comprises GPS transceiver 50 form.In order to realize caching function, utilize certain part of the storer (volatibility RAM or nonvolatile memory, such as flash memory) of subscriber equipment as Cache 53.By delay, the client correlation function that this delay is determined determines that mobile applications 51 realizes.Can carry out via the graphical user interface of such as touch-screen and so on the communication of user/passenger.This graphical user interface is used by a user in his/her route information of input especially, such as PNR number or means of transport through transport information for showing real time delay information.
On the other hand, server side 47 is provided services on the Internet to subscriber equipment 1.It comprises and keeps bottom data, particularly timetable 3, in detail with reference to the infrastructure of dispatch list 4 and log book 5.In the example that the real time delay for train calculates, server side infrastructure comprises rail distribution platform 54 (RDP), RaillT server 55 and database 56.
Figure 11 and 12 illustrates the example of the graphical user interface of exemplary smart phone 1, and by means of this graphical user interface, the software be arranged on smart phone 1 shows determined real time delay information to user.Main screen as described in Figure 11 show the identification information (" Intercity 12345 ") of means of transport, next plan station (" Pisa "), the next stop is relevant therewith the information that is ranked (being ranked arrivals at 19/10/2011 20:10), in the actual arrival of the estimation at this website place (" in the actual arrival of 19/10/2011 20:15 ") and delay (" delay: 5min ").Below further, the physical location at means of transport and some important station (" Napoli ", " Roma ", " Torino ") is indicated.Such as can be highlighted on those punctual websites of this place's means of transport with green background color particularly.Such as can be highlighted on red background color the website that this place's means of transport or probably will postpone in a different manner.User is guided to being ranked and calculating the tabular form sketch plan (illustrating with Figure 12) of arrival/departure time for primary site by the button being such as labeled as " dispatch list details " and so on.Additionally or alternatively, present section and be about to the arrival station of arrival and those complete list of be ranked arrival/departure time and calculating.
Finally, Figure 13 is the diagram of the inner structure of subscriber equipment 1.Subscriber equipment 1 is arranged to execution one group of instruction, performs any method discussed herein to impel it.Mobile communication equipment comprises processor 121, primary memory 122 and radio network interface 123 (such as Wi-Fi and/or blue tooth interface) and/or 2G/3G/4G mobile network interfacing equipment (not shown), and it all intercoms via bus 124 phase.It also comprises static memory 125, such as irremovable flash memory or solid-state drive or Moveable mini or small-sized SD card, and it for good and all stores and makes subscriber equipment 1 can perform local the delay to determine function and the software communicated with server side infrastructure 47.In addition, it comprises display 127, preferably touch-screen, user interface (touch-screen) control module 129 and additional (non-virtual (non-virtual)) alphanumeric and cursor input equipment 128 (if this type of input equipment exists) alternatively.Subscriber equipment 1 is connected to server side infrastructure 47 by wireless network interface devices 124.Optional GPS transceiver 126 provides position to determine.Any one or whole one group of instruction (i.e. software) 130 of embodying in said method fully or at least in part resides in static memory 125.When being performed, each instruction and/or data reside in primary memory 122 and/or processor 121.Can launch from/to the server in the server side infrastructure described by Figure 10 or the Internet as transmitting signal 132 or receive software 130 further by wireless network interface devices 123 or 2G/3G/4G.
