Below, the action of the traffic information system of this structure is described.
Fig. 8 shows the running order of traffic information system.Shown in Figure 8 like this, if vehicle A starting (S1), then begin communicate by letter between the control device 21 of the information terminal 1 of vehicle A and center fixture 20, send actuate message (S2) and the mobile record information of transmission successively.If the control device 21 of center fixture 20 receives the actuate message of vehicle A, then this actuate message is signed in in the starting resume database 23 and store maintenance (T1).The control device 21 of center fixture 20 is based on starting resume database 23 and the canned data of road through information database 24, and the current predefined paths (move predefined paths: current predetermined road section and time on date thereof) of inferring vehicle A (T2).At this moment, the control device 21 of center fixture 20 is inferred the current predefined paths of vehicle A based on the action model of vehicle A.
The transport information (traffic) of the current predetermined road section of the current predefined paths (moving predefined paths) of the control device 21 affirmation vehicle A of center fixture 20 has detected no abnormal (T3).Past that this said " unusually " is illustrated in vehicle A in constantly the highway section travel time and current transport information carried out have deviating from more than the setting between the highway section travel time of reflection; Imagination has reflected that the highway section transit time of current transport information compares the situation of more substantial time of needs with the highway section transit time in past; Under situation about having taken place with chronic lasting usual (usually) state different state (so-called ERST), in this step T3, be judged as " being ".The highway section L (road interval) that center fixture 20 will be in this ERST is estimated as the photographed images informational needs interval that is considered to needs in information terminal 1 side of vehicle A.
Next; Unusual highway section L takes place and confirms road through information database 24 (T4) in 21 pairs of the control device of center fixture 20, beyond vehicle A, extracts than vehicle A earlier the current preset vehicle (T5) that the current possibility of unusual highway section L is higher than specified degree is taking place.This also can extract based on the action model of vehicle, under the situation in the path till in information terminal 1, being set with the destination, also can extract based on this current predefined paths.
Sometimes the automobile storage that the current preset vehicle of conduct is extracted is a plurality of, and the control device 21 of center fixture 20 carries out the notice request (T6) of current location information to the information terminal 1 of these vehicles.If the control device 21 of center fixture 20 starts (U1) with vehicle B and begins communication as condition, in step T6, carry out notice request, then vehicle B notifies the control device 21 (U2) to center fixture 20 with actuate message and current location information.Among the information terminal that carries on a plurality of vehicles 1, have only the information terminal 1 of the vehicle that has started to communicate by letter, so reduced at this information terminal 1.
The starting resume database 23 that center fixture 20 is confirmed vehicle B and road be through information database 24 (T7), and the current predefined paths (moving predefined paths) of inferring vehicle B (T8).Inferring in the processing of the current predefined paths of this vehicle B; When in advance under the road of center fixture 20 situation through the road information that stores vehicle B in the information database 24; Can infer the current predefined paths (action model) of vehicle B based on the road information of this vehicle B; Ground has carried out under the situation of path setting till playing the destination from the departure place in the information terminal 1 at vehicle B, can infer current predefined paths through obtaining set path from the information terminal 1 of vehicle B.At this, it is interval current in condition that center fixture 20 is not predefined in the photographed images informational needs with vehicle, and the information terminal 1 of this vehicle is got rid of from option.Also reduced vehicle (information terminal 1) at this as object.
Next, 21 pairs of vehicle B indications of the control device of center fixture 20 are carried out image pickup (T9) to unusual highway section L takes place, and carry out the request of obtaining of photographed images information thus.The information terminal 1 of vehicle B is if accept the image pickup indication; Then when unusual highway section L takes place process, obtain photographed images information and be stored in internal storage (U3), will obtain the control device 21 (U4) of the fact notice center fixture 20 of photographed images information after shooting finishes.The control device 21 of center fixture 20 should the fact if accept, and then signs in to shooting information database 25 (T10).
If vehicle A near the highway section L that unusual road takes place (the photographed images informational needs is interval), near also not to and only depend on the point of crossing C (take-off point) (S3: be) of avoiding of this highway section L unusual (can carry out interval the avoidance), then the control device 21 of 1 pair of center fixture 20 of information terminal is asked photographed images information (S4).The control device 21 of center fixture 20 is through the shooting information (T11) of search this highway section L from shooting information database 25, confirms to obtain the situation of the photographed images information of vehicle B.
Then, traffic the when control device 21 of center fixture 20 is relatively made a video recording and current traffic are asked photographed images information (T12) to vehicle B under the situation of unanimity.This comparison process is to carry out through above-mentioned VICS information is compared.Under the traffic in when shooting and current traffic condition of different, the photographed images information of obtaining in vehicle B side has become old information, thus with the needed information inconsistency of vehicle A.In this case, information terminal 1 indication of 20 couples of vehicle B of center fixture abandons photographed images information.And, under traffic when shooting and the current traffic condition of different, traffic other the vehicle request photographed images information consistent during preferably to shooting with current traffic.And; Preferably the control device 21 of center fixture 20 is inferred the traffic of the interval current predetermined instant of the photographed images informational needs of vehicle A, will be judged as identical with this traffic, or with respect to this traffic not extreme variation (promptly similar, for example; Similar in VICS information medium green with Huang; Yellow and red similar, green and red not similar) as condition, it is useful and vehicle B is sent request photographed images information to be judged to be its photographed images information.
After the processing of step T12, the information terminal 1 of vehicle B sends to requested photographed images information the control device 1 (U5) of center fixture 20.The control device 21 of center fixture 20 receives this photographed images information (T13) and is stored in internal storage.Information terminal 1 then discharges storage area (U6) with the photographed images information of being obtained from the storer deletion if be through with the transmission of photographed images information to the control device 21 of center fixture 20.
In this case, the control device 21 of center fixture 20 also receives photographed images information from the information terminal 1 of a plurality of other vehicles (comprising vehicle B) sometimes.This is because vehicle A is to all having carried out the request of obtaining of photographed images information at the interval current high vehicle of possibility of photographed images informational needs.At this moment, the control device 21 of center fixture 20 is preferably from one of photographed images information selected or a spot of photographed images information of a plurality of other vehicles (comprising vehicle B).This be because; If vehicle A side has been sent more photographed images information; Then the information terminal 1 of vehicle A needs to select the part of this photographed images information that it is shown in the display frame of display device 9; In this case, the processing of the information terminal 1 of vehicle A load increases, and the traffic of Image Communication is increased.Therefore, center fixture 20 preferably will be reduced to its part from a plurality of photographed images information that a plurality of other vehicles send.In addition; At vehicle A to carrying out the request of obtaining of photographs information at the interval current high vehicle of possibility of photographs informational needs and obtain under the situation of a plurality of photographs information, obtain from the immediate time-lapse photography of the timing of requested image information to photographs information.
In this case, preferably the control device 21 of center fixture 20 be chosen in be estimated to be vehicle A will be before the time period current on the current predefined paths and the photographed images information of the vehicle that passed through with nearest inherent this photographed images informational needs interval of stipulated time scope (time period) of this time period.In addition; Can grasp at the control device 21 of center fixture 20 under the situation of current location of vehicle A; Preferably select as required and confirm can vehicle A arrive point of crossing C (take-off point) before (for example somewhat before～tens minutes before, before the for example also poor predetermined distance) finish the photographed images information of information terminal 1 of other vehicles of the transmission of photographed images information.
Then, the control device 21 of center fixture 20 sends to the information terminal 1 (T13) of vehicle A with photographed images information the time on date with shooting.The information terminal 1 of vehicle A reproduces the photographed images information of being accepted (S5).
More than; Show the information flow between the information terminal of center fixture and vehicle among the traffic information system S; Below; With reference to Fig. 9 and Figure 10; Situation about being applied in the real road is enumerated as an example, especially to the action model of vehicle A or vehicle B infer processings, unusual highway section L4 takes place, and inferring of (the photographed images informational needs being interval) handled and described in the processing of inferring that the high vehicle of the current possibility of unusual highway section L4 (the photographed images informational needs is interval) takes place.
Fig. 9 shows the supplementary notes figure of presuming method of the action model of vehicle.
The action model of each vehicle (vehicle A, B) utilizes mode (for example corresponding to the driver to vehicle; Mainly utilize on ordinary days; Utilize main off-day; Mainly utilize utilization such as mainly go for a drive a long way off etc. at possessory oneself periphery), car type (for example full-sized car, general-utility car, automotive bicycle) etc. changes.For example the driver under situation about on ordinary days vehicle being utilized as the unit of travelling frequently; Through confirm " Monday～Friday about AM7:30 from coordinate S (X0; set out Y0), through node N1～N5 and highway section L1～L6, about AM8:20, arrive coordinate (near X1; Y1) " the fact, can be estimated as action model (moving on ordinary days is scheduled to) on ordinary days.
Specifically; To from coordinate S (X0; Y0) number of times that sets out that sets out, arrival coordinate E (X1; Y1) arrival number of times and through the counting through cumulative frequency of each node N1～N5, highway section L1～L6 is judged as current termly these nodes N of L, highway section in these counts when above for regulation.In addition, the condition of assembly time section judge whether be on ordinary days action model, whether be the action model on off-day, whether be the morning action model, whether be the action model in afternoon, can infer action model thus.
Figure 10 shows based on the supplementary notes figure that infer processing of action model to inferring at the height that the current possibility in unusual highway section takes place.
In Figure 10, be expressed as highway section L4 with unusual highway section L (the photographed images informational needs is interval) takes place, in this Figure 10, illustrated as above-mentioned, infer out from the action model of vehicle A with his vehicle B, D, E.
Shown in figure 10, imagination vehicle A from coordinate S (X0, Y0) set out from the highway section L1～L6, node N1～N5 is current and move to coordinate E (X1 Y1) infers out as action model in center fixture 20 sides.
At this moment; The control device 21 of center fixture 20 in the step T2 of Fig. 8, be estimated as to pass through traffic jam does not take place when common and just between certain given period (for example, accident, when travelling frequently the peak) interval (the highway section L4: above-mentioned " unusually " interval) of traffic jam of traffic jam takes place.In addition, in this embodiment, be object with the traffic jam interval that traffic jam only just takes place between certain given period.This is because when chronic traffic jam took place the road of the daily repeated moving of user (travel frequently, go to school and leave school etc.), in most cases the user did not need the photographed images information of road.This also because; If traffic jam often takes place in the road of the daily repeated moving of user (travel frequently, go to school and leave school etc.); Then which kind of degree user's traffic jam state of knowing road is, for example when having obtained traffic jam information through VICS information etc., just can grasp the traffic jam state to a certain degree.
At this; Be in the place that traffic jam does not take place when common and the state (being equivalent to and usual different road condition) of traffic jam only just takes place between given period, can infer out through the shooting information database 25 shown in information database 24 (the highway section travel time in the specific road section) or Fig. 7 (in the specific road section by the shooting on each date time traffic) etc. according to the road shown in Fig. 6 by each date.Particularly preferably be; Center fixture 20 is directed against and usual different road condition; The mobile record information in traffic jam state (red, yellow, green etc.), highway section travel time, traffic jam length of an interval degree etc. and past compared judge that it is interval to be estimated as the photographed images informational needs.
Like this, center fixture 20 passes through as if being estimated as the predetermined interval part (highway section L4) of traffic jam that traffic jam is just taking place from for example usually traffic jam not taking place at present of vehicle A, and it is interval then this highway section L4 to be estimated as the photographed images informational needs.
Action model at other vehicles (vehicle B, D) is included in this highway section L4 under the situation in the action model, the control device 21 of center fixture 20 with these other vehicles (vehicle B, D) as selecting vehicle.On the other hand because the action model of vehicle E does not comprise highway section L4, so with vehicle E as non-selection.Like this, can judge whether other vehicles (vehicle B, D, E) are higher than regulation from the current possibility of unusual highway section L4 (the photographed images informational needs is interval) takes place.Can reduce the selection vehicle like this.
In addition, also can be such shown in the explanation of above-mentioned step U2, T7, T8, the control device 21 of center fixture 20 is considering to judge on the basis whether vehicle has started whether the current possibility of highway section L4 is higher than regulation.That is, if the actuate message of other vehicles (for example vehicle D) is not sent to center fixture 20 sides, the current possibility of L4 just is 0 to this vehicle D from the highway section so, so can be with this vehicle D as non-selection.
In addition; If consider the current location information of other vehicles (vehicle B, D, E); And this current location information is from the action model of imagination when departing from; Or relatively this current location information and highway section L4 positional information and be judged as when predetermined distance is above, it is low then can be judged as the possibility that L4 goes from the highway section clearly.Thus, can reduce and from this highway section the L4 high vehicle of possibility that goes.
In addition; Through navigation feature the information terminal 1 of vehicle A or other vehicles (vehicle B, D, E) has been preestablished from the departure place and to have played under the situation of the current predefined paths till the destination; Also can be to judge based on current predefined paths if these current predefined paths are sent to center fixture 20.Also can be; Judge whether it is to include the path that unusual highway section L4 (the shooting informational needs is interval) takes place at the control device of center fixture 20 21 to the current predefined paths of vehicle B; Be judged as under the situation that includes highway section L4, being judged as is the current high vehicle of possibility of L4 from the highway section.In this case, the control device 21 of center fixture 20 no longer need be inferred the action model of vehicle A, B, D, E through the canned data of information database 24 based on the canned data and the road of starting resume database 23.
