The index of " distance ", " time " when should " cost in highway section " being meant the route of estimating by this highway section, " passing through difficulty " etc. means " for the labour that expends by this highway section (route), expense, risk whole " comprehensively.Cost is meant easily for a short time by this highway section, and the cost in expense or labour, the highway section (route) that has a big risk is set greatly.For example, carry out following setting: the cost of major trunk roads such as national highway is 1, the cost of main roads such as county road is 2, the cost of the path through lifes such as road, village is 4, when being set to the travel route of destination, with the low mode setting path of highway section cost, thereby provide route information to the guider of contract vehicle.
In addition, by user's input device 201, input or set destination locations P2 (Fig. 2/S024) of motor vehicle 2 thus.Utilizing first handling part 210 is that navigation server 100 sends or uploads behind the identifying information of motor vehicle 2 in the homeposition P1 interpolation with the position P of the motor vehicle 2 under the input time t ' of destination locations P2, this destination locations P2 of motor vehicle 2 (t ').
Corresponding therewith, in navigation server 100, utilize the homeposition P1 of first support processing unit, 110 cognitron motor-cars 2 and destination locations P2 (Fig. 2/S012).In addition, utilize first support processing unit 110 to read the support cartographic information from supporting map reservoir 102, read detection data etc. from Traffic Information reservoir 104, and set support route R (Fig. 2/S013) of the homeposition P1 that links these motor vehicles 2 and destination locations P2 according to these sense informations.Support route R and be under the most excellent condition of combustion effect of motor vehicle 2 in the displacement of distance destination locations P2 or forecasting institute take time the shortest or travelling till the destination locations P2 and set.The cost consideration that the highway section that the area comprised takes place the disaster of being estimated by second support processing unit 120 when as described later, disaster being taken place is at interior and set supporting route R.
And then, utilize second support processing unit 120 to extract the highway section of part or all (Fig. 2/S014) from a plurality of highway sections of constitute supporting route R.In addition, the highway section identifying information that utilizes second support processing unit 120 will extract the highway section sends or downloads in this guider 200 to the guider 200 that carries on motor vehicle 2, and described motor vehicle 2 is discerned by the identifying information that is attached among the destination locations P2 etc.
Corresponding therewith, in guider 200, utilize second handling part 220 according to this highway section identifying information, utilize navigation map information that navigation map reservoir 204 stores, motor vehicle 2 homeposition (also can be input time with destination locations P2 different the time motor vehicle 2 inscribed current location) P1, the destination locations P2 of input before, set navigation way r as shown in Figure 4, and with this navigation way r with navigation map information to output unit 202 outputs (Fig. 2/S026).Need to prove that except that navigation way r, the current location P (t) of expression motor vehicle 2 and the icon of direct of travel (orientation) etc. are exported with navigation map information or shown.And then, utilize second handling part 220 that the highway section identifying information that constitutes whole highway section of navigation way r is added the identifying information of going up motor vehicle 2 after navigation server 100 send or upload.
Corresponding therewith, in navigation server 100, utilize 120 identifications of second support processing unit or store this highway section identifying information, and then identification or storage are according to the navigation way r that the highway section constituted of this highway section identifying information identification (Fig. 2/S015).
Second support processing unit 120 is discerned by stably communicating by letter with disaster information central server 10 and is had or not disaster to take place, and in the situation that disaster has taken place or take place under the high situation of the possibility of disaster, discerns this disaster area (Fig. 2/S016) takes place.In addition, second support processing unit 120 is extracted disaster the highway section that the area comprised (Fig. 2/S017) is taken place according to supporting cartographic information.
And then, the cost in this extraction highway section of second support processing unit, 120 evaluations (Fig. 2/S018).
This cost evaluation is carried out according to the detection data from separately detection data gathering-device 200c of brougham 2c, cart 2b, band class of vehicle ID that 200b obtains.
For example second support processing unit 120 with described disaster take place the back as Fig. 3 (a) shown in like that the cost of (following make like that the situation that direct of travel reverses except) highway section L1 that road comprised that frequency is high of all passing through of brougham 2c and cart 2b be evaluated as, four-wheel uses, two to take turns any cost of usefulness all low.This is owing to consider that the highway section L1 that road comprised that the frequency that brougham and cart all passed through after disaster took place is high is subjected to the influence of disaster few, therefore the possibility height of safety.
In addition, second support processing unit 120 with disaster take place the back as Fig. 3 (b) shown in like that brougham 2c with cart 2b the cost of the high highway section L2 that road comprised of the frequency of direct of travel counter-rotating or u turn is evaluated as, four-wheel uses, two to take turns any cost of usefulness all high.This is owing to consider, the back brougham takes place disaster makes the high highway section L2 that road comprised of frequency of direct of travel counter-rotating be subjected to the influence of disaster with cart, therefore can not assert safe possibility height.Need to prove that the highway section L1 among Fig. 3 (b) is the highway section that brougham 2c and cart 2b pass through, thus its cost be evaluated as four-wheel with, two to take turns any cost of usefulness all low.
In addition, second support processing unit 120 with disaster the back takes place, and the frequency passed through of cart 2b is high but the cost of the high highway section L2 that road comprised of the frequency of counter-rotating of brougham 2c direct of travel or the turning of U type is evaluated as like that as Fig. 3 (c) shown in, two to take turns the cost of usefulness low, the cost height that four-wheel is used.This is owing to consider, the influence that highway section that the above-mentioned road in back comprised is subjected to disaster takes place disaster, thus brougham 2c can't by but possibility height that cart 2b can pass through.And then, for two-wheel vehicle used cost,, carry out cost evaluation and the automobile-used cost evaluation of road running that offroad vehicle is used according to detection data that obtains from offroad vehicle (Fig. 7 (a)) and the detection data that obtains from road running car (Fig. 7 (b)).Need to prove, for two-wheel vehicle used cost, estimate the automobile-used cost this point of cost that offroad vehicle uses and road running in following evaluation too.
And then, second support processing unit 120 with Fig. 4 (a) though shown in be included in like that navigation way r (cost that the high highway section L2 that road comprised of the frequency that departs from from brougham 2c, both travel routes of cart 2b (2c), (2b) back takes place with reference to disaster among Fig. 2/S015) is evaluated as, four-wheel with, two to take turns the cost of usefulness all high.This is owing to consider, though be included among the navigation way r, but the highway section L2 that road comprised that disaster takes place to depart from from brougham 2c, both travel routes of cart 2b (2c), (2b) back is subjected to the influence that the disaster of the degree herein of avoiding brings of having to of brougham, cart, therefore can not assert safe possibility height.
In addition, second support processing unit 120 will be included in navigation way r like that (with reference among Fig. 2/S015) and the frequency height that back brougham 2c departs from from travel route (2c) takes place disaster but the cost of the low highway section L2 that road comprised of the frequency that cart 2b departs from from travel route (2b) is evaluated as shown in Fig. 4 (b), the cost height that four-wheel is used, two to take turns the cost of usefulness low.This is owing to consider, be included among the navigation way r, the back takes place and departs from but the highway section L2 that road comprised that do not depart from from the travel route (2b) of cart 2b is subjected to the influence of disaster from the travel route (2c) of brougham 2c in disaster, so brougham 2c can't by but possibility height that cart 2b can pass through.
In addition, the deviation of brougham 2c, cart 2b detection data separately before and after second support processing unit, 120 computing disasters take place, the cost in the highway section that road comprised that this deviation is big is estimated highly.This is owing to consider, the big highway section that road comprised of deviation of detection data was subjected to the influence of disaster before and after disaster took place, and therefore can not assert safe possibility height.For example, even have the detection data of same identifying information, but shown in Fig. 5 (a) like that the travel route of the detection data computing before disaster takes place, the cost of the highway section L2 that road comprised different with the travel route of detection data computing after the disaster generation estimated highly.Fig. 5 (a) expression brougham, cart are all avoided the state of highway section L2, and Fig. 5 (b) expression brougham 2c avoids highway section L2 but cart 2b does not avoid the state of highway section L2.Under the situation of Fig. 5 (a), the cost of highway section L2 be evaluated as four-wheel with, two to take turns the cost of usefulness all high, under the situation of Fig. 5 (b), it is high but two to take turns the cost of usefulness low that the cost of highway section L2 is evaluated as cost that four-wheel uses.
And then, second support processing unit 120 is estimated the cost in the highway section that following road comprised high, the volume of traffic of the motor vehicle 2 of the detection data computing before described road is meant and takes place from disaster or average transit time, with take place from disaster after the volume of traffic of motor vehicle 2 of detection data computing or the different roads of averaging time above threshold value.
As described above, second support processing unit 120 is carried out the cost evaluation in highway section according to the detection data from separately detection data gathering-device 200c of brougham, cart, band class of vehicle ID that 200b obtains, and road (highway section) is divided into:
The road (highway section) that brougham and cart both can not pass through;
Brougham can not by but road (highway section) that cart can pass through;
The road (highway section) that brougham and cart both can pass through,
And estimate, and estimate the generation Traffic Information according to this.
In addition, for the road that cart can pass through, further divide into both roads that all can pass through of offroad vehicle (Fig. 7 (a)) and road running car (Fig. 7 (b)), only the offroad vehicle road that can pass through is estimated, and estimate according to this and to generate Traffic Information.
Need to prove, the length in the elapsed time after also can taking place according to the distance disaster, selectivity adopts described a plurality of method.In addition, also can finally estimate the cost that the regional highway section that is comprised takes place disaster from its initial value thus according to described method increase and decrease by the cost that disaster is taken place in the regional highway section that is comprised.Promptly can with take place to disaster before till detection data and the initial value of the corresponding cost of Traffic Information at Traffic Information center it doesn't matter ground the sets cost in each highway section after disaster takes place, the cost till before also can taking place by near disaster add and the corresponding original initial value of setting the cost in each highway section after the disaster generation that becomes takes place disaster.And then, even in same highway section, also can make cost differential according to the difference of disaster type.For example, in supporting cartographic information portion, the information of the combination of additional representation disaster type and cost in the identifying information of highway section, when utilizing second support processing unit 120 except that the area takes place disaster, also to discern disaster type (earthquake, fire, floods etc.), according to this disaster type the cost in each highway section that this area comprised is carried out after the initial setting, the cost of this initial value finally being estimated as described above each highway section according to the detection data increase and decrease also can.In addition, the initial value of the highway section cost of earthquake generation region is set at earthquake intensity or earthquake magnitude is big more then high more, and the initial value of the cost in the disaster generation highway section that the region comprised also can according to the degree set of disaster.And then the initial value of the cost in the disaster generation highway section that the region comprised is set at without exception also can than the highway section height of other region.
And second support processing unit 120 generates and sets the support route R that links homeposition P1 and destination locations P2 (Fig. 2/S013) in the mode that preferentially comprises the low highway section of cost.This support route R according to described Traffic Information generate support route that brougham uses and two-wheel vehicle used support route the two.For two-wheel vehicle used cost, generate support route and the automobile-used support route of road running that offroad vehicle is used.In addition, second support processing unit 120 is extracted the highway section (Fig. 2/S014) is with highway section identifying information navigation device 200 transmissions as with disaster corresponding Traffic Information taking place in this extractions highway section from supporting route R as mentioned above.Need to prove, also can be positioned at disaster and take place under area or its situation in the neighbourhood, with supporting Traffic Information navigation device 200 transmissions of route when irrespectively the cost in the highway section that this area comprised being taken place as disaster with the highway section identifying information at the current location P of motor vehicle 2 (t).
As the guider 200 of the transmission object of corresponding Traffic Information taking place, selectedly carry, support route R or be included in disaster from the current location P (t) that detection data is grasped guider 200 on the motor vehicle 2 in area or its environs takes place at homeposition P1, destination locations P2 with disaster.
Corresponding therewith, in guider 200, second handling part 220 for example can be set and export such navigation way r shown in the solid line among Fig. 6 when disaster takes place, the nonevent navigation way r when common of such disaster shown in the single-point line is different among this navigation way r and Fig. 6.
All can not be under the situation of travelling on the L2 of highway section at brougham 2c and cart 2b, 220 couples of brougham 2c of second handling part, cart 2b set navigation way r such shown in Fig. 6 (a) and output, can not travel on the L2 of highway section but cart 2b can be under the situation of travelling on the L2 of highway section at brougham 2c, shown in Fig. 6 (b), brougham 2c is set navigation way rc and the output that brougham 2c uses, cart 2b is set navigation way rb and the output that cart 2b uses.In addition, for two-wheel vehicle used navigation way rb, though not shown, divide into the automobile-used navigation way of navigation way that offroad vehicle uses and road running and set and export.
According to the navigational system of the described function of performance, extract disaster the highway section that the area is comprised takes place, and respectively the cost that these extract highway sections is estimated according to detection data that (Fig. 2/S016～S018 is with reference to Fig. 3～Fig. 5).On the space of the motor vehicle of representing by detection data 2 and reflect the possibility height of the influence that disaster is brought in the temporal mobile pattern.Thereby, can estimate the cost that each highway section in area takes place disaster the height of security be used as this each highway section reliably in view of the disaster situation of reality and condition of road surface.In addition, send by the Traffic Information navigation device 200 that will generate according to the cost in each highway section, thus can be by guiding this motor vehicle 2 with output of disaster generation corresponding navigation route r navigation device 200 etc., thereby can be in view of the disaster situation of reality and condition of road surface and make motor vehicle 2 avoid the influence of this disaster (Fig. 2/S026 is with reference to Fig. 6).
Below, the cost evaluation in the highway section that second support processing unit 120 is carried out and describe based on the further concrete example that the support route of this evaluation generates.
Fig. 8 is the concise and to the point figure of an example of expression disaster road condition that the area takes place, (a) is the figure of the road condition of (at ordinary times) before the expression disaster takes place, and (b) is the figure of an example of the cost in this highway section of expression.
For example, in order to simplify, with at ordinary times cost as following with range-independence be set at simple value (with reference to Fig. 8 (b)).
Hollow thick line among ■ main line road (national highway etc.) figure ... cost=1
Center line among ■ main roads (county road etc.) figure ... cost=2
Fine rule among ■ the path through life (road, village etc.) figure ... cost=4
Shown in Fig. 8 (a), under situation at ordinary times, for from supporting our department's (disaster is provided with the position of supporting our department when taking place) for the route in for example A area, the route of four-wheel (A1～A4) have four, (M1～M4) have four, the highway section cost of each route is as described below for two routes of taking turns.
Route A1 (M1): 12 (=1+1+2+2+2+4)
Route A2 (M2): 5 (=1+4)
Route A3 (M3): 3 (=1+2)
Route A4 (M4): 10 (=1+1+2+2+4)
Guider is pressed the low select progressively route of highway section cost, so under situation at ordinary times, selection schemer A3 (M3).
Fig. 9 is the concise and to the point figure of an example of the road condition of this area after the expression disaster takes place, and (a) is the figure of an example of road condition after the expression disaster takes place and the detection data that obtains from this area, (b) is the figure of the example estimated of the cost in this highway section of expression.In Fig. 9 (a), with similarly above-mentioned, solid arrow 2c represents the driving trace of brougham, and dotted arrow 2b represents the driving trace of cart.
According to such detection data shown in Fig. 9 (a), second support processing unit 120 can be to judging towards the route in for example disaster-stricken A area is for example following from supporting our department like that.
Therefore about route A1 (M1), four-wheel and two is taken turns and can both be passed through, and does not need to change the cost in the highway section that this route comprises.
About route A2 (M2), four-wheel (2c) carries out the U type at highway section L2 turns, but two take turns (2b) and can pass through, so the cost of highway section L2 needs to improve for four-wheel, does not need change but take turns two.
About route A3 (M3), four-wheel and two is taken turns all and to be carried out the U type at highway section L3 and turn, so the cost of highway section L3 is still taken turns two four-wheel and all needed to improve.
Route A4 (M4) too, four-wheel and two is taken turns all and to be carried out the U type at highway section L4 and turn, but the cost of highway section L4 still be two to take turns and all need raising for four-wheel.
According to for example judgement as described above, the cost in each highway section after 120 pairs of disasters of second support processing unit take place is for example estimated shown in Fig. 9 (b) like that.
About the cost of highway section L2, only four-wheel is for example changed to " 30 " from " 4 ".
About the cost of highway section L3, L4, still be two to take turns and Yan Doucong " 2 " for example changes to " 30 " no matter to four-wheel.
Consequently, after disaster takes place, become following such towards the highway section cost of each route in disaster-stricken A area from supporting our department.
About brougham,
Route A1:12 (=1+1+2+2+2+4)
Route A2:31 (=1+30)
Route A3:31 (=1+30)
Route A4:38 (=1+1+2+30+4)
About cart,
Route M1:12 (=1+1+2+2+2+4)
Route M2:5 (=1+4)
Route M3:31 (=1+30)
Route M4:38 (=1+1+2+30+4)
Thereby second support processing unit 120 is after disaster, and only setting path A1 is as the support route that is used for the navigation way rc that four-wheel uses, and setting path M1 and M2 are as being used for the two support routes of taking turns the navigation way rb of usefulness.
In above-mentioned example, " only cart can pass through highway section " L2 is constant for two costs of taking turns, but in fact also considers the infringement that is subjected to a certain degree, therefore also for example can be increased to about " 8 " or " 10 ".In addition, constant for the offroad vehicle cost, but for example can be increased to about " 8 " or " 10 " the road running car.
