< traffic administration collection of server image >

Fig. 3 is the process flow diagram that traffic administration server 200 gathers image.

First, with reference to figure 4 (A), many that on the way travel vehicle 300A without camera head or have the vehicle 400A of camera head that the vehicle traveling information (vehicle ID, longitude, latitude, time etc.) of self is uploaded to traffic administration server 200 (arrow F1) in real time.A kind of format sample of vehicle traveling information is given in Fig. 5.Traffic administration server 200 is after receiving vehicle traveling information by communication module 210, to be calculated the travel speed on the driving trace Ji Ge road chain of each car according to the driving information of each vehicle by jam level analysis module 230, by adding up in section sometime (in such as nearest 10 minutes) by the travel speed of many cars of this road chain, calculate the individual jam level (step S360) of population mean jam level on this road chain and each car.

In the present invention, the jam level of road defines according to the travel speed of vehicle, and Fig. 6 gives both corresponding relation example a kind of.

In variance analysis module 240, more above-mentioned population mean jam level is identical one by one with each car individual jam level separately, when having the individual jam level that exceedes both certainty ratios (such as 50%) and population mean jam level not to be inconsistent, then judge that this road chain is as " deviation road chain ", otherwise belong to " non-deviation road chain " (step S361).

If certain road chain belongs to " non-deviation road chain ", then traffic administration server 200 Bu Duigai road chain carries out image acquisition, and this flow process terminates.

If certain road chain belongs to " deviation road chain ", then in Deviation Type identification module 250 to causing the reason of this deviation to be further analyzed (step S362).Analytical approach be by (in such as nearest 10 minutes) in a period of time by the vehicle of this road chain according to travel route tagsort, whether the average jam level then calculating each class vehicle respectively identical with population mean jam level.If different, then judge that such travel route feature is one of reason caused a deviation.May there is multiple deviating cause in Mei Tiao road chain, the deviating cause of each road chain is stored in data memory module 220 simultaneously.

Below, " travel route feature " in step S362 is described in detail.In embodiment 1, the criteria for classification of travel route feature is: next the road chain entered after leaving this deviation road chain according to vehicle divides.Such as, in the figure 7, the deviation road chain analyzed at present is L0, and after supposing that vehicle leaves from deviation road chain L0, its travel route has following 4 kinds of possibilities: turn right and enter Exit Road chain L1, craspedodrome enters Exit Road chain L2, turn left to enter Exit Road chain L3, turn around to enter Exit Road chain L4.Therefore, according to above 4 kinds of Exit Road chains, all vehicles running over deviation road chain L0 can be divided into 4 classes according to its travel route feature.

Next, enter Exit Road chain L1 to bend to right, illustrate and how to identify whether a certain class travel route feature is the reason causing road chain deviation.(in such as nearest 10 minutes) in a period of time are divided into a class through the vehicle of chain L0 laggard inlet/outlet road, deviation road chain L1, calculate the average jam level of this class vehicle on the chain L0 of deviation road, compared with the population mean jam level then calculated on the chain L0 of road with all vehicles.If inconsistent, such as from the road chain L0 average jam level of vehicle entering road chain L1 of turning right be " unobstructed ", and the population mean jam level of all vehicles is " jogging " on the chain L0 of road, both are inconsistent, then think that " leaving chain L0 laggard inlet/outlet road, deviation road chain L1 " this travel route feature is one of reason causing road chain L0 deviation.Except Exit Road chain L1, other Exit Road chains L2, L3, L4, also may be the reason causing road chain L0 deviation, namely may there is the multiple travel route feature that can cause a deviation in a deviation road chain simultaneously, and these are all stored in data memory module 220.A kind of form example storing deviation road chain and deviating cause thereof is given in Fig. 8.

After above-mentioned analysis, if the deviating cause of deviation road chain fails to identify, Ze Buduigai road chain carries out image acquisition; If can identify the reason causing road chain deviation, then traffic administration server 200 will carry out image acquisition for this deviation road chain.Because the driving information of vehicle uploads to traffic administration server 200 in real time, therefore, traffic administration server 200 can judge which vehicle is positioned near the chain of deviation road.As shown in Fig. 4 (B), the image information request module 260 of traffic administration server 200 sends image taking indication information (step S363) (arrow F2) to the vehicle 400B of camera head that has near the chain of deviation road.Fig. 9 gives a kind of format sample of image taking indication information.

" camera site " in image taking indication information is relevant with the type of the road chain that causes a deviation.In embodiment 1, road chain deviation is that different Exit Road chains causes, and therefore camera site is set near the chain terminal of road (before such as road chain terminal within the scope of 30 meters).

Figure 10 gives the flow process of the vehicle 400B collection image of camera head.First, image taking instruction (step S380) that the vehicle 400B of camera head reception traffic administration server 200 is sent is had.Then, vehicle 400B indicates according to image taking, when arrive assigned address and time-out (arrive in the time of camera site and the interval of request time be no more than the time interval preset) take image (step S381).Next, image and relevant image data information are made image information data bag (step S382) by vehicle 400B.Finally, vehicle 400B sends image information data bag to traffic administration server 200 (step S383), with reference to figure 4 (C) (arrow F3).Figure 11 gives a kind of format sample of image data information.

After traffic administration server 200 receives image information, examined by the driving trace of image information receiver module 270 to these images and shooting vehicle thereof.Examine content can include but not limited to: judge that whether image information is overtime, whether image-capturing place conforms to image taking request, whether the travel route feature of taking the vehicle of this image information conforms to causing the reason of road chain deviation, and whether the individual jam level of taking the vehicle of this image information conforms to the average jam level corresponding to this deviating cause of this deviation road chain.If meet above-mentioned condition through examining, then by described image information and relevant data information memory thereof in data memory module 220 (step S364).For a certain travel route feature caused a deviation of same deviation road chain, one or more image informations that a retention time is up-to-date.Figure 12 gives a kind of format sample of the image data information after traffic administration server 200 is analyzed.

So far, the flow process that traffic administration server 200 gathers image terminates.

< traffic administration server issues image >

Next, illustrate that in embodiment 1, traffic administration server 200 issues the steps flow chart of image.

As shown in flow process Figure 13, first, traffic administration server 200 obtains the trip alternative route (step S370) of user.The trip alternative route of user can be inputted by user, also can be that user inputs departure place and destination, by the navigation system computes route out of traffic administration server or vehicle.As shown in the arrow F4 in Fig. 4 (D), the information of user's input is sent to traffic administration server 200 by the communication module of vehicle 300C or vehicle 400C.

In image information release module 280, whether the alternative route judging user exists deviation road chain (step S372).If there is no, then without the need to sending image information to user; If there is deviation road chain, then continue to judge, for these deviation road chains, in data memory module 220, whether to store the image (step S374) user being had to reference value.Judge whether the standard of reference value including but not limited to: the travel route feature of user on the chain of deviation road belong to cause image that in one of reason of this road chain deviation, data memory module 220, existence conforms to the alternative route feature of user, the individual jam level of vehicle when taking this image of taking this image is consistent with the average jam level of the vehicle of this type of routing characteristics current, this image not time-out (if image capturing time is within 10 minutes) etc.When meeting above-mentioned standard, think that image has reference value for route of user.If there is no the image of reference value is had, then without the need to sending image information to user; If have the image of reference value, then the image information that issue is consistent with the alternative route feature of user on these deviation road chains gives this user (step S376), with reference to the arrow F5 in figure 4 (D).

Provide the concrete example that image information is issued below.As shown in Figure 14 (A), first the traveling alternative route R1 of oneself is uploaded to traffic administration server 200 by user.This route R1 is made up of Duo Tiao road chain, wherein comprises a deviation road chain L0, and estimates after leaving road chain L0 that next the road chain entered is L1.Draw through traffic administration server 200 analysis, it is one of reason causing road chain L0 deviation that the routing characteristics of user " leaves road chain L0 laggard approach chain L1 ", the image information of the vehicle shooting " left road chain L0 laggard approach chain L1 " with route of user feature and be consistent is had in data memory module 220, during image information shooting, corresponding jam level is consistent (being such as all " unobstructed ") with the average jam level " leaving road chain L0 laggard approach chain L1 " under current traffic condition, and this image information not time-out (if image capturing time is within 10 minutes).Therefore, traffic administration server 200 judges that this image information has reference value for the routing characteristics of user.

So, as shown in Figure 14 (B), on the display interface of user, except by traditional mode on Mei Tiao road by different colors except user label " unobstructed ", " jogging ", " blocking up ", also can point out to user on the chain of road devious.If user is interested, can select to check image information, as shown in Figure 14 (C).

So far, the flow process that traffic administration server 200 issues image terminates.

Below, compared with prior art, the difference in embodiment of the present invention 1 is described.

Traffic congestion is shown to user by image information, more more directly perceived than only using word and color, and decrease the understanding difference of different drivers in jam level.

On the chain of deviation road, only carry out collection and the issue of image information, gather on the chain of whole roads with patent documentation 1 and issue image and compare, decreasing memory data output and data processing amount, alleviate the burden of traffic administration server.Meanwhile, due to image information being issued by the deviation road chain only in user's travel route, so decrease the quantity of user's image browsing information, the time of stroke planning is shortened.

Adopt vehicle-mounted camera to gather image information, compared with the monitoring camera of roadside, as long as the road having vehicle to run over just can gather image, instead of be only limitted to the road having installed camera, therefore, it is possible to improve the coverage rate of image.On the other hand, the image information that vehicle-mounted camera gathers can from the details of the visual angle reflection pavement behavior of vehicle, simultaneously, same path can also collect the image information from multiple different viewing angles, also make to provide variation on same path, differential traffic-information service becomes possibility.

The image information that user receives issues by with other vehicles that user has an identical travel route feature, and therefore with on a road chain issue compared with identical transport information to all users, have more specific aim, the accuracy of information of issue is higher.

(variation of embodiment 1)

Above, embodiment of the present invention 1 has been described in detail, but this embodiment also can change as follows.

Specifically, about the structure of traffic administration server, the structure eliminating the Deviation Type identification module 250 shown in Fig. 1 and image information release module 280 can be adopted, that is, traffic administration server can adopt the structure only possessing communication module 210, data memory module 220, jam level analysis module 230, variance analysis module 240, image information request module 260 and image information receiver module 270.Correspondingly, about the flow process of the traffic administration collection of server image of this structure, the content of the step S362 in Fig. 3 can be omitted.

According to the traffic administration server of this variation, can judge whether each road chain is deviation road chain by jam level analysis module and variance analysis module, thus the collection of image information is only carried out for deviation road chain, therefore, compared with the technology contents gathering image information on the chain of whole roads disclosed in above-mentioned patent documentation 1, decrease memory data output and data processing amount, the burden of traffic administration server can be alleviated.

(embodiment 2)

Below, embodiments of the present invention 2 are described.

In embodiment 1, the criteria for classification of travel route feature is: the different Exit Road chains entered after leaving deviation road chain.With embodiment 1 unlike, in embodiment 2, the criteria for classification of travel route feature is: the different destinations (i.e. the terminal of travel route) of travel route.Here " destination " specially refers to be positioned at the destination on the chain of described deviation road.

Specifically, a road chain may exist one or more point of interest (POI, Point ofInterest), these points of interest likely become the destination that some vehicle travels.As shown in figure 15, using the point of interest on the chain of road as the vehicle of destination, the travel speed on this road chain, individual jam level may be different from other vehicles because queuing up, finding the behaviors such as parking stall near destination.That is, the destination be positioned on the chain of road also may be one of reason causing road chain deviation.

Therefore, in embodiment 2, according to the destination of vehicle on the chain of deviation road, vehicle can be classified.All on the chain of road the vehicle on ground for the purpose of same point of interest, be considered to have identical travel route feature.

So, in embodiment 2, the image acquisition flow process (Fig. 3) suitably adjusted in embodiment 1 and image are issued the process of classifying to travel route feature in the corresponding steps of flow process (Figure 13).As: identify deviation road chain reason (step S362), send image taking instruction (step S363), receive image information storages (step S364) of classifying, judge whether route of user there is deviation road chain (step S372), transmission customized image information is to user (step S376) etc.Below, for the step identical with embodiment 1 no longer repeat specification, emphasis has the step of adjustment to be specifically described to above-mentioned.

In embodiment 2, the step S362 in embodiment 1 is adjusted as follows.When the deviating cause of an analysis deviation road chain, if travelled in all vehicles on this deviation road chain, have the destination of vehicle to be just in time positioned on this road chain, so by these vehicles according to its different destinations classification on the chain of deviation road.Such as, in Figure 16, travel in the vehicle on the chain of current road, the destination of some vehicle is just in time positioned on this road chain.Suppose that these gross vehicles have these two destinations of D1 and D2, so the vehicle on ground for the purpose of D1 can be divided into a class, for the purpose of D2, the vehicle on ground is divided into another kind of.If this class vehicle on ground for the purpose of D1, on their average jam level and this deviation road chain, the population mean jam level of all vehicles is not inconsistent, then think that " for the purpose of D1 " this travel route feature is one of reason causing this road chain deviation.In like manner, also can analyze " for the purpose of D2 " whether be one of reason causing road chain deviation.The analysis result of deviating cause is all stored in data memory module 220.Give when deviating cause is different destination in Figure 17, store the form example of deviation road chain and deviating cause thereof.

After determining deviating cause, the image information request module 260 of traffic administration server 200 has the vehicle 400B of camera head to send image taking indication information (step S363) (arrow F2) near the chain of deviation road.Wherein, with embodiment 1 unlike, in the image taking indication information shown in Fig. 9, when the deviating cause of road chain is destination, camera site is set in (before such as destination within the scope of 30 meters) near this destination.If deviation road chain exists multiple deviating cause simultaneously, then the travel route feature that can cause a deviation for often kind sends image taking instruction respectively.

In like manner, when receiving image information and classification stores (step S364), the Deviation Type in image data information form also has adjustment with additional information compared with embodiment 1, as shown in figure 18.

When step S372 judges whether route of user there is deviation road chain, change the destination judging route of user into and whether be positioned on the chain of deviation road.

In step S376, when sending customized image information to user, traffic near its destination can be pointed out not identical with average traffic situation to user, and image details can be checked, as shown in Figure 19 (A), (B).

The effect of embodiment 2 is, the jam level near the destination of user, and when being different from the traffic of the population mean jam level of place road, destination chain, traffic administration server can issue image information as prompting to user.The vehicle taking this image has identical destination with user, so the image information issued more has reference value to user.

(embodiment 3)

Below, embodiments of the present invention 3 are described.

In embodiment 1 and embodiment 2, when sending image taking instruction (step S363), the image information request module 260 of traffic administration server 200 is to the vehicle 400B broadcast transmission image taking indication information having camera head near the chain of deviation road.That is, no matter there is the travel route of the vehicle 400B of camera head, all image taking indication informations having the vehicle 400B of camera head to receive near the chain of deviation road are identical.

With embodiment 1 and embodiment 2 unlike, in embodiment 3, have the predicted travel route of the vehicle 400B of camera head to upload in advance and be stored in the data memory module 220 of traffic administration server 200.Therefore, traffic administration server 200, before the instruction of transmission image taking, can judge that each has the travel route feature of the vehicle 400B of camera head whether to be consistent with the deviating cause of current deviation road chain in advance.If met, and vehicle 400B is just travelling on the chain of described deviation road or is being about to sail described deviation road chain into, then traffic administration server 200 sends the image taking indication information corresponding to its travel route feature by this vehicle.If do not met, traffic administration server 200 can not send image taking indication information to incongruent vehicle.

Specifically, for Fig. 7, if cause the reason of road chain L0 deviation to only have " leaving road chain L0 laggard approach chain L1 ", Exit Road chain L2, L3, L4 can not cause the deviation of road chain L0, so only when the travel route feature of vehicle 400B is " leaving road chain L0 laggard approach chain L1 " and this vehicle is just travelling or is being about to sail on the chain L0 of deviation road, traffic administration server 200 just can send image taking indication information to this vehicle.Exit Road chain is that the vehicle of L2, L3, L4 can not receive the image taking indication information of traffic administration server 200 on the chain L0 of deviation road.

Embodiment 3 is compared with embodiment 1, newly-increased effect is, when traffic administration server 200 is to more targeted when having the vehicle 400B of camera head to send image taking instruction, decreases the data volume of communication, also improve the treatment effeciency of the vehicle 400B of camera head.
