The road data of state variation identifying unit 35 based on being collected by road data collector unit 34, determines whether some state variation occurs the road 20 of management object.For example, state variation identifying unit 35 is obtained visibility situation from the road data being obtained by visibility meter 11, by obtained visibility situation and the visibility situation comparison of (before) before this, determines whether state variation has occurred.
In addition, whether state variation identifying unit 35 for example also can compare the current visibility situation and the predefined threshold value that obtain from road data, carry out decision state and worsen.In this situation, state variation identifying unit 35 is for example that 100m is set as visibility scale " well " above in the situation that at visibility distance, visibility scale is set as to " poor " in the situation that being less than 100m, carries out the judgement of state variation.
In addition, state variation identifying unit 35 compares the car speed obtaining from millimeter wave sensor 12 or the cross section volume of traffic and car speed or the cross section volume of traffic of (before) before this, determines whether generation state variation.
In addition, state variation identifying unit 35 for example can compare the current car speed of obtaining from road data or the cross section volume of traffic and predefined threshold value, judges whether state worsens.In this situation, state variation identifying unit 35 for example can be obtained that vehicle 21 stops or travelling above with low speed driving or with common speed, judges the state variation of road 20 according to its result.
For example, state variation identifying unit 35 can be considered as at car speed " stopping " lower than first threshold in the situation that, at car speed between first threshold and Second Threshold in the situation that, be considered as " low speed ", faster than Second Threshold in the situation that, by speed class be set as common speed with on carry out the judgement of state variation.Wherein, first threshold is such as, such as, according to road category (ordinary road, super expressway etc.), road construction (straight line, bend, ramp etc.) and difference for example can be set as about approximately 10 to 20km/h.In addition, Second Threshold is set to the speed faster than above-mentioned first threshold, for example, can be set as about approximately 30 to 40km/h, but first and Second Threshold be not limited thereto.
Pavement behavior infers that unit 36 is being judged to be by state variation identifying unit 35 in the vicissitudinous situation of pavement behavior of road 20, infers the pavement behavior of road 20.For example, pavement behavior is inferred visibility situation and the car speed obtaining from millimeter wave sensor 12 or the cross section volume of traffic that the visibility meter 11 of unit 36 based on from above-mentioned obtains, and infers whether the pavement behavior of the road 20 of management object worsens.In addition, the deterioration grade (for example worsen a little, very worsen) of pavement behavior also can be inferred in condition of road surface deduction unit 36.In addition, condition of road surface deduction unit 36 also can, except inferring the situation of pavement behavior deterioration, also infer that pavement behavior becomes good situation.
For example, pavement behavior infers that unit 36 also can use the date and time information corresponding with the road data of being obtained by each determination unit (visibility meter 11, millimeter wave sensor 12 etc.) etc. to obtain information in season (for example summer or winter), infers pavement behavior accordingly with obtained information in season.For example, pavement behavior infers that unit 36 can obtain the positional information (such as latitude longitude, height above sea level) etc. that is provided with each determination unit (visibility meter 11, millimeter wave sensor 12 etc.), infers accordingly pavement behavior with obtained positional information.
Thus, for example, if for example season, information was situation or the higher situation of height above sea level in winter (about Dec to February), pavement behavior infers that unit 36 can carry out piling up on road surface the deduction of snowy grade more rightly.
For example, pavement behavior infer unit 36 also can according to based on carrying out the visibility meter 11 that comfortable 1 or multiple place arrange, the road data of millimeter wave sensor 12 is inferred the inferred results of pavement behavior, infers the pavement behavior at the place place of set destination.In addition, the pavement behavior after a few hours also can be inferred by the inferred results of current pavement behavior and statistics in the past etc. in pavement behavior deduction unit 36.
The result of determination of notice identifying unit 37 based on being obtained by state variation identifying unit 35, determines whether supvr is notified.In addition, notice identifying unit 37 also can be inferred that the inferred results of unit 36 determines whether based on pavement behavior supvr is notified.
Notice identifying unit 37 can such as, according to the inferred results of the result of determination of above-mentioned state variation, pavement behavior (deterioration degree) etc., selects the supvr that will notify in predefined 1 or multiple supvr.
For example, if be inferred as the degree of " road surface is piled up snowy ", notify identifying unit 37 to notify road management person and traffic administration person, if be inferred as the degree of " worsen a little on road surface ", " having degradating trend ", notify identifying unit 37 only road management person to be notified.

The example > that < state variation is judged
Next an example that, utilizes accompanying drawing to judge the state variation in present embodiment describes.Fig. 6 is the figure that represents an example of state variation judgement.In the example of Fig. 6, presented in diagrammatic form respectively time of obtaining from visibility meter 11 and relation and the time obtaining from millimeter wave sensor 12 and the relation of speed of visibility distance, but also can not generate in the present embodiment chart.The time of each chart has been obtained synchronously.
In addition, in the example of Fig. 6, the road data that the visibility meter 11 that certain place (place 1) of the road of above-mentioned chart based on from management object is set and millimeter wave sensor 12 are obtained, but also can be from other places (for example place 2 ..., place n) obtains same chart.State variation identifying unit 35 also can be by above-mentioned each chart of each ground dot generation, makes output unit 32 displays such as grade show the chart generating and make the confirmations such as supvr.
Thus, state variation identifying unit 35 can be judged the state variation at each place place, and can carry out based on the result of determination in multiple places the judgement of more appropriate state variation.
For example, as shown in Figure 6, visibility distance (distance from visibility meter) and the predefined threshold value etc. based on being measured by visibility meter 11 obtains the state that visibility worsens to state variation identifying unit 35.In addition, state variation identifying unit 35 uses the speed and the predefined speed that obtain from millimeter wave sensor 12 grades, obtains the state of the Speed Reduction of the vehicle 21 passing through in this place.In the present embodiment, can use above-mentioned information to detect simply the variation of situation, can hold rightly the deterioration of the visibility at this place place, the time of Speed Reduction.In addition, in the present embodiment, also can be to grades such as visibility setting " good ", " poor ", to the grade of Speed Setting " conventionally more than speed ", " low speed ", " stopping ".About " good ", " poor " of visibility, for example can be by being that 100m is made as " good " above by visibility distance, will be less than 100m and be made as " poor " and set visibility scale, but be not limited thereto.In addition, about speed class, for example can judge as " stopping " lower than the situation of first threshold compared with predefined threshold value, for the situation between first threshold and Second Threshold judges as " low speed ", judge as " conventionally more than speed " in the situation that is greater than Second Threshold.Setting gimmick about visibility scale, speed class is not limited thereto.
Pavement behavior infers that unit 36, by using visibility scale as described above, speed class etc., can carry out the deduction of road surface (traffic) rightly for the variation of state.In addition, the judgement of state variation can be not be carried out based on the result of the three unities only yet, and variation that can be based on for example judge the state on road surface according to the statistics of the state variation to this place place of the resume in the variation of the state in continuous multiple places, past etc.The result of determination that state variation identifying unit 35 also can collect the state variation at 1 or multiple place place is judged the state variation in regulation interval.
In addition, the judgement to state variation in present embodiment is not limited to above-mentioned content, for example also can replace speed and use the cross section volume of traffic, set traffic rank by the cross section volume of traffic and predefined threshold value, and carry out the judgement of state variation with the traffic rank of setting.
An example > of < pavement behavior inference process
Next, an example of the pavement behavior inference process in present embodiment is described.For example, pavement behavior infers that unit 36 can use visibility meter 11 and millimeter wave sensor 12 measured value and predefined deduction table etc. separately, infers pavement behavior simply.Or notice identifying unit 37 can use visibility meter 11 and millimeter wave sensor 12 measured value and predefined deduction table etc. separately, decides the sending destination that notify.
Fig. 7 is the figure that represents an example of deduction table.In the table example of Fig. 7, be set with " pavement behavior inferred results ", " having undirected gerentocratic notice ", " kind of notice destination (supvr) " that " speed class " and " visibility scale " based on above-mentioned infers.
For example, for example, about the speed class in the example of Fig. 7 (" conventionally speed more than ", " low speed ", " stopping "), visibility scale (" good ", " poor "), can set based on predefined threshold value as described above, but be not limited thereto.In addition, the number of grade is also not limited to the example of Fig. 7.
For example, pavement behavior is inferred the in the situation that unit 36 at speed class being " conventionally more than speed ", independently pavement behavior is made as to " good " with " good ", " poor " of visibility scale.In this situation, because supvr does not need to carry out any reply, so notice identifying unit 37 does not carry out to gerentocratic notice (not notifying).In addition, notice judges and is not limited thereto, for example, be " conventionally speed more than ", visibility scale be " good " in the situation that at speed class, pavement behavior can be inferred as to " having dry possibility " and notify to supvr (road management person).Supvr is by utilizing manager terminal 14 to receive notice as described above, can utilize at the surveillance camera of the road setting of object etc. and carry out Visual Confirmation situation, for example, take that road management person is sent to the instruction of setting out that utilizes water barrow to carry out aproll and wait reply rapidly.
In addition, pavement behavior infers that unit 36 can be " low speed ", visibility scale for " good " in the situation that at speed class, is inferred as " although being that fine day is icing or have a dropping " as pavement behavior.In this situation, worsen a little owing to being inferred as pavement behavior, so notice identifying unit 37 is notified inferred results to the supvr's corresponding with above-mentioned inferred results (road management person) manager terminal 14.Supvr is by utilizing manager terminal 14 to receive notice as described above, utilize at the surveillance camera of the road setting of object etc. and carry out Visual Confirmation situation, for example can take to road management person send spraying snow-melting agent, remove dropping etc. set out the replies rapidly such as instruction.
Wherein, as mentioned above, in road data, comprise temporal information.Therefore, pavement behavior infer unit 36 can determine season according to temporal information, if summer deducibility be that " road surface is likely moistening " is as pavement behavior.In addition, if winter, pavement behavior infers that unit 36 deducibilitys are for " there is icing possibility on road surface " is as pavement behavior.In addition, in the present embodiment, use the contained positional information of road data, if for example locating, as near the place (the foot of a mountain) of height above sea level of road data can be inferred as " there is icing possibility on road surface ".In the present embodiment, by using contained temporal information, the positional information of road data, can carry out the deduction of more appropriate pavement behavior.
In addition, pavement behavior infers that unit 36 be " low speed ", visibility scale for " poor " in the situation that at speed class, and deducibility is that " having the possibility of snowfall or mist " is as pavement behavior.In this situation, worsen a little owing to being inferred as pavement behavior, so notice identifying unit 37 is notified inferred results to the supvr's corresponding with above-mentioned inferred results (road management person) manager terminal 14.Supvr is by utilizing manager terminal 14 to receive notice as described above, can utilize the Visual Confirmation situations such as the surveillance camera that arranges at the road of object, for example, can take to notify to driver replies rapidly such as noting report by user's terminal 15, road information plate 16 etc.
Wherein, pavement behavior infers that unit 36 can determine season according to above-mentioned temporal information, if summer, is inferred as " likely because mist or rainfall cause the road surface moistening " as pavement behavior.In addition, if winter, pavement behavior infers that unit 36 can be inferred as " likely because of snowfall accumulated snow " as pavement behavior.In addition, pavement behavior infers that unit 36 can use above-mentioned positional information, if locating as the place of height above sea level of road data is inferred as " there is icing possibility on road surface ".
In addition, pavement behavior infers that unit 36 be " stopping ", visibility scale for " good " in the situation that at speed class, and deducibility is that " having the possibility of the accident that occurred " is as pavement behavior.Wherein, accident comprise the accident that do not cause because of pavement behavior (such as traffic hazard, independent fault etc.), the accident that causes because of pavement behavior (for example skid, sandstone landslide, lower junk etc.) etc.
In this situation, whether be because of stopping that pavement behavior causes owing to distinguishing, so there is road management, person and traffic administration person both sides rush towards on-the-spot possibility, therefore notify identifying unit 37 two kinds of gerentocratic manager terminal 14 to be carried out to the notice of inferred results.About notice now, extremely worsen and need urgent reply owing to being inferred as pavement behavior, so can represent the notice of the content of emergency notice.Supvr is by utilizing manager terminal 14 to receive notice as described above, can utilize the surveillance camera that arranges at the road of object etc. and Visual Confirmation situation is taked the rapid reply corresponding with situation.
In addition, season can be determined according to above-mentioned temporal information in pavement behavior deduction unit 36, if be inferred as " possibility that road surface has moistening (water logging) " as pavement behavior summer.In addition, if winter, pavement behavior infers that unit 36 can be inferred as " there is icing possibility on road surface " as pavement behavior.In addition, in the present embodiment, can use the contained positional information of road data, if locating as the place of height above sea level of road data is inferred as " there is icing possibility on road surface ".In the present embodiment, by using contained temporal information, the positional information of road data, can carry out the deduction of more appropriate pavement behavior.
In addition, pavement behavior infers that unit 36 be " stopping ", visibility scale for " poor " in the situation that at speed class, and deducibility is that " possibility that has snowfall or mist " is as pavement behavior.In this situation, notice identifying unit 37 carries out the notice of inferred results to the supvr's corresponding with above-mentioned inferred results (road management person) manager terminal 14.About notice now, extremely worsen and need urgent reply owing to being inferred as pavement behavior, so can represent the notice of the content of emergency notice.Supvr is by utilizing manager terminal 14 to receive notice as described above, can utilize the surveillance camera that arranges at the road of object etc. and Visual Confirmation situation, for example, take by user's terminal 15, road information plate 16 etc., driver to be notified the rapid reply of noting report etc.
In addition, season can be determined according to above-mentioned temporal information in pavement behavior deduction unit 36, if be inferred as " there is moistening possibility on road surface " summer as pavement behavior.In addition, if winter, pavement behavior infers that unit 36 deducibilitys are for " having the possibility of the accumulated snow causing because of snowfall (snowstorm) " is as pavement behavior.In addition, pavement behavior infers that unit 36 can use above-mentioned positional information, if locating as the place of height above sea level of road data is inferred as " having the possibility that causes accumulated snow because of snowfall (snowstorm) ".
In the present embodiment, shown in the example of Fig. 7 described above, even if speed class is the state of " low speed ", by being the data combination of " good " or " poor " by visibility scale, also can distinguish as being icing (or dropping) or snowfall.Therefore, for example whether road management person can need rapidly to rush towards on-the-spot reply.
In addition, in the present embodiment, even if visibility scale is the state of " good ", by being " low speed " or the data combination for " stopping " by speed class, also can distinguish the problem or the accident (or disabled vehicle) that are inferred as road surface.Therefore, can judge rapidly and need to rush towards on-the-spot be road management person or traffic administration person (police etc.).
And, in the present embodiment, even if the state that speed class is " stopping ", by by visibility scale being the data combination of " good " or " poor ", also can judge rapidly that the person that needs road management and traffic administration person both sides rush towards scene, or road management person can tackle by long-range instruction etc.
In the present embodiment, by presetting the supvr (road management person etc.) in the situation of carrying out as shown in Figure 7 common notice and carrying out the supvr (road management person, traffic administration person etc.) in the situation of emergency notice, can notify the supvr corresponding with grade, the inferred results etc. of state variation.
If adopt other performance, for example notify identifying unit 37 can infer according to the result of determination being obtained by state variation identifying unit 35, pavement behavior the Output rusults of unit 36, come Notification of Changes destination.Each of the communication line that the computing machine that the communication line connecting due to the computing machine only utilizing for road management person in the case of necessary utilizes with traffic administration person is connected sends notice, so can suppress to increase for the load of communication line.
In addition, notice identifying unit 37 carries out identical notice in the case of the supvr to identical, can not carry out notice more than stipulated number.In this situation, notice identifying unit 37 can be selected other supvrs that not yet notify and notification unit 38 is notified.
For example, in the example of above-mentioned Fig. 5 (B), 5 minutes volume of traffic measuring under common speed 8OKm/h at 13: 30 according to millimetre-wave radar are 200, but at 19: 15, speed based on certain reason vehicle becomes 30Km/h, and the volume of traffic of 5 minutes is also down to 40/5 minutes.In addition, if observe visibility scale, the visual field that can enumerate 19 o'clock is down to 50m and is used as reason.In addition, pavement behavior infers that unit 36 can obtain temporal information, is inferred as " moistening " as the pavement behavior in summer according to these information, is inferred as " accumulated snow " pavement behavior as winter.
In the present embodiment, if snowfall in the winter time substantially, many regions that freezes, reduction that can be based on visibility, is inferred as snowfall simply.And if car speed reduces, to be driver underspeed because of the impact of snowfall in deducibility.In addition, in the present embodiment, underspeed if visibility does not reduce, can be inferred as simply icing possibility.
In addition, in the present embodiment, can carry out to judge more accurately pavement behavior by information such as the pavement temperatures of use weather information (current weather, weather forecast), temperature, humidity, road upper surface.Because bad (poor) of visibility or this information of reduction of car speed are all to represent abnormal information for road management person, so inform supvr to judge aspect situation it is very important as digital value.
As mentioned above, according to present embodiment, can be suitable for gerentocratic road management auxiliary.For example,, according to present embodiment, even if supvr does not always monitor the inferred results that road also can be based on pavement behavior and the reply that should carry out outputs such as road management persons.Therefore, supvr can discover rapidly the abnormal of road, and by going on patrol as triggering or surveillance camera confirmation, can carry out rapidly situation judgement accurately.In addition, according to present embodiment, can implement rapidly the road management business such as snow removing, Snow Agent sprinkling.Thus, the reply that can should carry out outputs such as road management persons.
