Description
Technical field
The present invention relates to field of navigation technology, particularly a kind of navigational system reaches air navigation aid and the device based on Real-time Traffic Information.
Background technology
Along with the development of automobile industry, people are when having automobile, and the user who more and more pays close attention to when using automobile experiences.Existing mobile unit can offer the user and much serve, and comprises the service of the multimedia demands such as music, video, picture, and the service of the traffic navigation aspect such as real-time road condition information, destination maps etc.Especially the use of onboard navigation system is more and more universal, can guide the user to drive by the voice suggestion of navigational system, especially when travelling in strange city, can help the user to arrive quickly and easily the destination by navigational system.
In recent years, the dynamic navigation technology is noticeable one new application of intelligent transportation field, and it is so that vehicle-mounted or hand-held mobile terminal is widely used, and this has proposed new challenge to map of navigation electronic and multidate information Visualization.
Map of navigation electronic (abbreviation electronic chart) is called again navigation electronic, and its main contents comprise geographical frame information, stack social and economic information and the static state/dynamic information thereon take road network as skeleton.Navigational system requires to support map match, path planning, Route guiding, map to show and the navigation data of related interests point inquiry.
Real-time traffic channel (TMC, Traffic Message Channel) is exactly the Real-time Traffic Information (comprising real-time road, traffic events etc.) that we often say, the function system as agps system (GPS, the Global Position System) navigation in Europe the earliest.The whole world mainly contains three kinds of these type systematics, is respectively the TravTek system of the U.S., the VICS system of Japan and RDS-TMC (the RDS:Radio Data System) system in Europe.Wherein, the RDS-TMC in Europe is a kind of real-time traffic sending and receiving system based on FM broadcasting.At present, TMC not only has been confined to traffic information, can also transmit Weather information, and final development develops and may be able to transmit many real time informations such as parking position, cinema are taken a seat, have dinner in the restaurant.Certainly, from the information that provides, the more effect of present stage TMC is to inform the Real-time Traffic Informations such as driver's congestion in road degree, burst traffic events, traffic control.
At present, to the research of the real-time traffic map traffic map of issue on the net that focuses mostly on, mainly from Geographic Information System (GIS, Geographic Information System) angle is set out complicated, a large amount of the visual of traffic data is studied, as the thematic overlap data in essence the data of Real-time Traffic Information, take the static map data as background, both are carried out Overlapping display.Therefore, the Real-time Traffic Information that navigator (usually using maximum in-vehicle navigation apparatus that is) receives all is that the form that directly is superimposed upon on the electronic chart shows basically, for example: the Real-time Road situation in highway section (block up, jogging or unimpeded) is that the lines with the green three kinds of colors of reddish yellow directly are superimposed upon on the road of electronic chart, general red expression is blocked up, yellow expression jogging, green expression is unimpeded.In the prior art, when the user need to understand the road traffic condition in certain city, navigator generally can be obtained the Real-time Traffic Information in all highway sections in this city, and demonstrate the Real-time Road situation in all highway sections at electronic chart based on the Real-time Traffic Information that obtains, soon the Real-time Road situation in each highway section is superimposed upon on the road of electronic chart with the lines of different colours, be convenient to the real-time road that the user understands in the certain area (for example certain district in city or city), thereby can bring certain reference to user's trip.And, Real-time Traffic Information also is used to planning and the guiding of guidance path more and more as an important consideration factor, for example: the Real-time Traffic Information when certain bar highway section shows that this highway section is in congestion status, then navigator is when the calculation guidance path, can avoid this highway section as far as possible, and select other alternative highway sections.
Yet, if need to grasp in real time the road traffic condition in whole city, then need frequently obtain the Real-time Traffic Information in all highway sections in whole city, could realize the renewal of the road traffic condition in whole city, but so cause the data volume processed larger, can obviously increase the burden of navigational system; And, be in the user of navigation in the traveling process for (by guidance path), show that at electronic chart the real-time road in all highway sections can cause the navigation screen that demonstrates complicated, the road indistinguishable, the navigation that has a strong impact on the user is experienced.

Embodiment
In the prior art, if need to grasp in real time the road traffic condition in whole city, then need frequently obtain the Real-time Traffic Information in all highway sections in whole city, the data volume of processing is larger, the burden of navigational system is heavier, and for the user of navigation in the traveling process, shows that at electronic chart the real-time road in all highway sections can cause the shown navigation screen that goes out complicated, the road indistinguishable has a strong impact on user's experience of navigating.
The inventor considers, for the user, its major concern or its stroke in the real-time road in highway section, and be indifferent to the real-time road in all highway sections that whole city or electronic chart show.The real-time road in a navigational system acquisition unit minute highway section if (highway section of being concerned about such as the user) then can alleviate processing load, and can also improve navigation efficient.Therefore, the technical program navigation stroke that the user is required is combined with TMC, by obtaining the corresponding Real-time Traffic Information in each highway section on the path of navigation (guidance path), and based on described Real-time Traffic Information, in the guiding interface that generates according to described path of navigation, indicate the Real-time Road situation in each highway section of described path of navigation, thereby can be on the basis of the burden that alleviates navigational system, make the user convenient, clearly know the real-time road in the navigation traveling process, and then can in time adjust path of navigation, the experience that has improved thus navigation efficient and strengthened the user.
For above-mentioned purpose of the present invention, feature and advantage can more be become apparent, below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail.
Set forth detail in the following description so that fully understand the present invention.But the present invention can be different from alternate manner described here and implements with multiple, and those skilled in the art can do similar popularization in the situation of intension of the present invention.Therefore the present invention is not subjected to the restriction of following public embodiment.
Fig. 1 is the schematic flow sheet based on the air navigation aid of Real-time Traffic Information that embodiment of the present invention provides.As shown in Figure 1, described air navigation aid based on Real-time Traffic Information comprises:
Step S101 carries out guidance path based on navigation request and calculates to obtain path of navigation, and described path of navigation comprises at least one highway section;
Step S102 obtains the corresponding Real-time Traffic Information in each highway section with described path of navigation;
Step S103 based on described Real-time Traffic Information, indicates the Real-time Road situation in each highway section of described path of navigation in the guiding interface that generates according to described path of navigation.
The below elaborates to above-mentioned air navigation aid with specific embodiment.
In the present embodiment, implement described air navigation aid based on Real-time Traffic Information as an example of onboard navigation system (comprising in-vehicle navigation apparatus) example, in other embodiments, also can be other navigator, such as the mobile phone that possesses navigation feature, multimedia terminal etc.
Those skilled in the art know, in onboard navigation system, usually with existing city map as a setting, then vehicle is located information (such as course information of the residing latitude and longitude information of vehicle, the vehicle etc.) Overlapping display of acquisition via satellite on Background (electronic chart).In the navigation procedure, because vehicle travels at road all the time, therefore the road network data in the existing electronic map database can provide road information, and shows as a setting with other information.In the vehicle mounted guidance process, require in real time vehicle location on electronic chart, and for huge city road network data, not taking rational data structure to come organising data is the requirement of real time that is difficult to satisfy navigation.Therefore, generally can take the mode of minute tape index, a so-called minute tape index is exactly to being in the road network in the whole city in the electronic chart coordinate system, divide band along X-direction (or Y direction) according to certain interval, bandwidth can be decided according to the actual requirements (for example, desirable 100m or 200m); Then the reference position of every band is stored from small to large or from big to small, simultaneously every road is given a unique road markings number (ID), road boundary rectangle (the minimax coordinate range of road) is dropped in the band origin coordinates corresponding stored with this band ID number of road.Especially, when to being in the road network in the whole city in the electronic chart coordinate system, when dividing simultaneously band along X-direction and Y direction, then formed present widely used gridding storage organization.In this structure, each piece grid has generally been stored a certain section (also may be entire road) of one or more road, can be described as again the highway section.
In road network, although being divided into many highway sections, a road is stored among the different grids, have annexation between these highway sections and the highway section; On the other hand, also may there be annexation between the highway section of the highway section of a road and other one or more roads.Therefore, the Origin And Destination in highway section all can be described as node, by nodes all in the road network is numbered, junction between highway section and the highway section is because having identical node, so what compile number is identical, so just the annexation between all highway sections can be stored in the electronic map database.For instance, ID number that supposes certain bar road is 302, and this road is divided into 4 sections, be stored in respectively among 4 grids, these 4 highway sections have the node of 5 different numberings, if numbering is respectively 1,2,3,4,5, these 4 highway sections can be expressed as 1-2,2-3,3-4,4-5 so.In addition, can also express the current direction in highway section, for example, 1-2 represents respectively the current direction that this highway section is different from 2-1, if this highway section belongs to one-way traffic, that storage only is 1-2 or 2-1 so, if two way, then 1-2 and 2-1 are stored simultaneously.Suppose that also having ID number of the bar road is 303, it comprises 2 highway sections, wherein highway section is connected with the road that is 302 for ID number, also have and be numbered 2 node, these two highway sections that are so 303 road for ID number are expressed as 2-6,6-7, similarly, if these two highway sections are two ways, then can also be expressed as 6-2,7-6.Need to prove, more than just simply the expression mode of annexation between the current direction in highway section, highway section, highway section is given an example, during implementation, each the bar highway section that is stored in electronic map database also has its unique ID number, road section ID (Link ID) is one of the base attribute in highway section, in addition, under the node that comprises of highway section, the highway section under the road attribute in the ID of road, highway section (such as being surface road or overpass), the highway section layer numbering etc. be the attribute in highway section.
Consult Fig. 1, execution in step S101 carries out guidance path based on navigation request and calculates to obtain path of navigation, and described path of navigation comprises at least one highway section.Particularly, when the user need to inquire about traffic route from a position to another position, can be with reference position (or being called current location) and final position (or being called destination locations) the input onboard navigation system of vehicle, certainly, the current location of vehicle also can be located via satellite (for example GPS) and directly be obtained, and does not need the user manually to input.Produce navigation request after starting inquiry, after onboard navigation system receives described navigation request, carry out the guidance path calculation based on described navigation request (information that comprises reference position and final position), obtain the traffic route from the reference position to the final position after the calculation, this traffic route namely is called path of navigation.Described path of navigation comprises at least one highway section, usually formed by many highway sections, and wherein a highway section must have an identical node with another highway section, namely has annexation between these two highway sections, so, the highway section that has an annexation has connected and composed described path of navigation successively.
Need to prove, more than one of described path of navigation is because through after the navigational system calculation, the scheme of drawn traffic route is also not exclusive, generally can calculate many traffic routes, that finally presents to the user then is the scheme of relatively optimum traffic route.Certainly, the parameter that also can impose a condition according to the actual requirements, the shortest such as running distance, running time is the shortest, vehicle cost is minimum etc., for different conditional parameters, the path of navigation that draws may be different, also may be identical.Technology about the guidance path calculation is conventionally known to one of skill in the art, does not repeat them here.
Behind the described path of navigation of guidance path calculation acquisition, then can (be mainly the information in each highway section according to the information that described path of navigation comprises, comprise annexation between highway section title, road section length, highway section direction, highway section etc.) generate guiding interface (or being called navigation interface), by described guiding interfacial energy path of navigation intuitively, is clearly showed the user, during implementation, described guiding interface is to show by the display screen of in-vehicle navigation apparatus.
A kind of mode that path of navigation is showed in the guiding interface is form by path list (turning to tabulation).Fig. 2 is the synoptic diagram at the guiding interface showed of prior art.As shown in Figure 2, there is shown the guiding interface that generates according to the path of navigation that obtains after the guidance path calculation, it has comprised two zones, is respectively zone 20 and zone 21, and wherein the content in the zone 20 is an example of path list.
Continue to consult Fig. 2, suppose that the user prepares to drive towards People's Square from the driving of Shanghai crossdrift one tunnel Weihai road, then through after the guidance path calculation, the path of navigation that obtains based on calculation generates the guiding interface, in it path list that comprises, show the information of reference position, i.e. " starting point A: Jing'an District, Shanghai City crossdrift one road Wei Hailu ", also show the information in final position, i.e. " terminal point B: Shanghai People's square ", and, the main information in each highway section that path of navigation is included also, each highway section title for example, on the way through the order in highway section, travel direction (direction of combining road), every distance of travelling in the highway section, annexation between the highway section and turn to situation etc. is showed one by one.For instance, 1 to 5 sequence number is corresponding " Wei Hailu ", " Huang Po North Road ", " people main road ", " Tibet Zhong Lu ", " Wusheng road " respectively, both shown the title in each highway section, has also shown on the way the order through the highway section; " sail " direction (this highway section on Weihai road is east-west direction) that then combines the highway section along Weihai road direction is eastbound and shown the travel direction of vehicle; " 966 meters ", " 76 meters " etc. show the length in each bar highway section, i.e. the vehicle distance of travelling in every highway section; " Wei Hailu " is that " Huang Po North Road " then shows between these two highway sections to have annexation afterwards, and " left-hand rotation enters the Huang Po North Road " further shows by " Wei Hailu " and travel to the situation that turns in " Huang Po North Road ".
Yet, the inventor finds, although path list can more clearly be expressed each highway section main information of path of navigation, but generally also only indicate the title in each highway section in the path list, the highway section direction, the information such as road section length, at most also a title with the highway section highlights with boldface letter, if and the user need to be known the condition of road surface in each highway section on the path of navigation in real time, then generally the Real-time Traffic Information in all highway sections, whole city can only be showed on the electronic chart, and the Real-time Traffic Information that need to frequently obtain all highway sections in whole city just can be guaranteed the renewal to the real-time road in whole city, so, the user is difficult on the basis that alleviates the navigational system burden, know easily in the navigation traveling process real-time road in each highway section on the path of navigation, thereby can not in time adjust path of navigation.For example: when the user travels according to the path of navigation that calculates out, blocking up has appearred in the traffic of supposing certain the bar highway section on the path of navigation, yet the user but can not in time be known this situation, still travel to this highway section by path of navigation, the result is trapped in this highway section and has caused expending a large amount of time, and if can be before reaching this highway section just in time know the real-time road in this highway section, just can consider to adjust path of navigation, namely re-start the guidance path calculation, upgrade path of navigation.
In addition, the another kind of mode that path of navigation is showed in the guiding interface is form by steering map (navigation map).Still consult Fig. 2, the content among Fig. 2 in the zone 21 is an example of steering map.Still prepare to drive to drive towards People's Square as example from Shanghai crossdrift one tunnel Weihai road take the user, after the guidance path calculation, the path of navigation that obtains based on calculation generates the guiding interface, the formed roadway line chart of path of navigation has been shown in it steering map that comprises, wherein, stain among the figure represents the node in each highway section of path of navigation, is respectively node a, node b, node c, node d, node f totally 6 nodes; The position at node a place is starting point A (Jing'an District, Shanghai City crossdrift one road Wei Hailu), and the position at node f place is terminal point B (Shanghai People's square).Can consult Fig. 2, described path of navigation generally is to be superimposed upon (the not shown urban road Background among Fig. 2) showed on the described steering map with overstriking and/or highlighted lines, described path of navigation is comprised of 5 highway sections, can represent " Wei Hailu ", " Huang Po North Road ", " people main road ", " Tibet Zhong Lu ", " Wusheng road " with highway section a-b, highway section b-c, highway section c-d, highway section c-d, highway section d-e respectively.Highway section a-b has an identical node with highway section b-c, show that these two highway sections have annexation, in like manner, highway section b-c and highway section c-d, highway section c-d and highway section d-e, highway section c-d and highway section d-e have respectively an identical node, show to have respectively annexation between these highway sections.In addition, every the highway section also is showed on the described steering map with different directions and length, be east-west to, highway section b-c such as the highway section a-b that can visually see be northwest-southeastern direction etc., the length of the highway section a-b that also can visually see is long, the length of highway section b-c is short etc.
Yet, the inventor finds, although steering map can be more directly perceived, clearly express the annexation in each highway section of path of navigation, the highway section direction, road section length, turn to the information such as situation between the highway section, even path of navigation is superimposed upon on the described steering map with overstriking and/or highlighted lines shows, and as previously mentioned, if the user need to be known the Real-time Road situation in each highway section on the path of navigation, then need frequently obtain the Real-time Traffic Information in all highway sections in whole city, could (be electronic chart at described steering map, because in navigation procedure, showing described path of navigation, so be called steering map or navigation map) the upper displaying that realizes the Real-time Road traffic in whole city, so, the user is difficult to equally on the basis that alleviates the navigational system burden, know easily in the navigation traveling process real-time road in each highway section on the path of navigation, thereby can not in time adjust path of navigation.
Therefore, go back execution in step S102 in the embodiment of the present invention, obtain the corresponding Real-time Traffic Information in each highway section with described path of navigation.
Those skilled in the art know, and Real-time Traffic Information mainly comprises 3 classes such as real-time traffic stream information (or being called real-time road condition information), traffic events and mobile object (such as vehicle) information, comprises in addition the information such as traffic weather, parking lot.The real-time traffic stream information can reflect traffic continuously, expresses the congestion status of road as the dynamic attribute of road key element, is most widely used in present navigation Service.Traffic events mainly refers to the traffic accident that Unpredictability is stronger, such as the event such as traffic hazard, road be unusual.In Transportation Data Collection Terminal, data are from different sensors, and the parameter that characterizes traffic stream characteristics is also varied, and in navigation Service is used, needs a single dimension parameter to express intuitively state or the congestion information of road.Average travel speed V commonly used
iAs the expression parameter of the telecommunication flow information on i the highway section, it is the amount of a numeric type, and this desired value is larger, illustrates that road is more unimpeded; Otherwise, illustrate that the highway section degree of blocking up is serious.Road-section average travel speed V
iCan be exchanged into the dynamic roadlock K of Traffic Net
i, be used for dynamic route planning; Also can be exchanged into congested in traffic degree C
iK
iOr C
iAs the dynamic attribute of road element, need the frequent updating data.In order to improve data storage efficiency, when carrying out Organization of Data, telecommunication flow information separates storage with static road network information, related with logic road network (road that navigation electronic is stored) with transport information highway section coding (RTIC Link ID has defined the numbering in each highway section, nationwide).Because the highway section of storing in real road and the electronic map database is not to concern one to one, therefore will by the transport information highway section encode (RTIC Link ID) set up the related of real-time traffic stream information and logic road network.At present, China RTIC (Road Traffic Information Coding) coding is as the basis take existing transport information road codes in the world, formulate for the special road conditions of China, adopted by traffic information management departments such as Beijing, Shanghai, Guangzhou.For guaranteeing that the real-time traffic stream information is associated with highway section in all kinds of electronic map database, must store the relation of the one-to-many of Link in RTIC Link and the logic road network in electronic map database (generally stores with the form of mapping table, the coded format of Link is different in the logic road network of the electronic map database storage that different electronic chart suppliers provides, therefore need to set up different corresponding relations for different electronic map database, namely store corresponding mapping table), by this corresponding relation with the telecommunication flow information dynamic mapping to every highway section, and can real-time update local (navigator) traffic data.
During implementation, the TMC data are issued by TMC service provider, onboard navigation system can arrange service end, be used for obtaining the TMC data and setting up the TMC database with this from TMC service provider, in-vehicle navigation apparatus on the vehicle is by network channel (3G for example, GPRS etc.) or broadcast channel (RDS-TMC for example, China Mobile multimedia broadcasting (CMMB, China Mobile Multimedia Broadcasting) etc.) obtain required TMC data from described service end, and based on the corresponding relation between the coding of highway section in the logic road network of RTIC Link ID and electronic map database storage, the required TMC data that get access to are changed.So Real-time Traffic Information described in the embodiment of the present invention mainly refers to through the TMC data after the conversion.
Need to prove that what obtain among the present embodiment step S102 is the Real-time Traffic Information in each included highway section of the path of navigation that calculates out by step S101, but not the Real-time Traffic Information in all highway sections in (for example city) in the certain area.In the prior art, when the user need to understand the road traffic condition in certain city, onboard navigation system can be obtained the Real-time Traffic Information in all highway sections in this city usually, and it is shown at electronic chart, brought certain reference for user's trip.But, vehicle in the process of moving, if need to constantly grasp the road traffic condition in whole city, then need frequently obtain the Real-time Traffic Information in all highway sections in whole city, thereby can realize the renewal of the road traffic condition in whole city, but the data volume of so processing is larger, can obviously increase the burden of onboard navigation system.In fact, the inventor considers, for (the pressing path of navigation) user in the navigation traveling process, it is general, and what more pay close attention to is the Real-time Road traffic in the highway section that comprises in the described path of navigation, Real-time Road traffic as for other highway sections, as long as when the user adjusts path of navigation, remove again to obtain the Real-time Traffic Information of respective stretch, so, just do not need to go continually to obtain the Real-time Traffic Information in all highway sections in whole city, only need obtain Real-time Traffic Information corresponding to highway section on the path of navigation, and the data volume of the Real-time Traffic Information in highway section is less on the path of navigation, can greatly alleviate the burden of onboard navigation system.In addition, when some guidance path calculation, also the Real-time Traffic Information in these all highway sections, city can be participated in calculation as important parameter, usually, in path calculation process, be in the highway section of unimpeded state with respect to the highway section that is in congestion status, it is selected as the possibility of the part of path of navigation higher.But after calculating out path of navigation, because the Real-time Traffic Information in the highway section on this path of navigation is constantly changing, therefore, the highway section that also is in unimpeded state when calculation then might become congestion status after after a while.If take to re-start at regular intervals the guidance path calculation, although can address the above problem, constantly performing calculations to take the resource of more navigational system, has increased the burden of navigational system.Thus, the inventor considers to adopt mode easily and efficiently that the Real-time Traffic Information in the highway section on the path of navigation is immediately showed the user, makes things convenient for the user to know real-time road in the navigation traveling process, and then can in time adjust path of navigation, improves navigation efficient.
After getting access to the corresponding Real-time Traffic Information in each highway section of described path of navigation, execution in step S103, based on described Real-time Traffic Information, in the guiding interface that generates according to described path of navigation, indicate the Real-time Road situation in each highway section of described path of navigation.
Because guiding comprises path list in the interface, the Real-time Road situation that therefore indicates each highway section of described path of navigation in the guiding interface comprises: the Real-time Road situation that indicates each highway section of described path of navigation in described path list.Particularly, the title that comprises each highway section of described path of navigation in the described path list, the Real-time Road situation that indicates each highway section of described path of navigation in described path list comprises: show the title in each highway section in the described path list with different colors, the color of the title in shown highway section is corresponding with the Real-time Traffic Information in this highway section.For instance, can be in conjunction with Fig. 2, suppose to get access to each highway section " Wei Hailu ", " Huang Po North Road ", " people main road ", the Real-time Traffic Information of " Tibet Zhong Lu " shows that respectively the Real-time Road state in highway section is " unimpeded ", " jogging ", " block up ", " sealing ", then in path list, three words of the title in highway section " Wei Hailu " are set to green and show (green expression is unimpeded), " Huang Po North Road " four words are set to yellow and show (yellow expression jogging), " people main road " four words are set to redness and show (red expression is blocked up), and " Tibet Zhong Lu " four words are set to grey and show (grey represents road closed).Certainly, in other embodiments, title that not only can the highway section is set to different colors and shows, the boot statement of the corresponding delegation in certain bar highway section in the path list can also be put on and the corresponding color of Real-time Traffic Information, green to show that " Wei Hailu " is in unimpeded state such as " 1. travelling 966 meters eastwards along Wei Hailu (unimpeded) " full line being denoted as.In addition, when reality is implemented, be not that each bar highway section can both get access to Real-time Traffic Information, the short highway section of possible some length does not provide Real-time Traffic Information, suppose not get access to Real-time Traffic Information corresponding to " Wusheng road ", can indicate especially this moment to " Wusheng road ", still shows to the user with the black boldface letter.
Certainly, also can adopt other mode in path list, to indicate the Real-time Road situation in each highway section in the embodiment of the present invention.Particularly, the Real-time Road situation that indicates each highway section of described path of navigation in described path list comprises: add the note of the Real-time Road situation in reflection highway section in described path list after the title in each highway section, described note is corresponding with the Real-time Traffic Information in this highway section.Fig. 3 is the synoptic diagram at the guiding interface showed of air navigation aid that embodiment of the present invention provides.As shown in Figure 3, there is shown the guiding interface that generates according to the path of navigation that obtains after the guidance path calculation, it has comprised two zones, is respectively zone 30 and zone 31, and wherein the content in the zone 30 is an example of path list.Still the Real-time Road state that shows respectively the highway section take the Real-time Traffic Information that gets access to each highway section " Wei Hailu ", " Huang Po North Road ", " people main road ", " Tibet Zhong Lu " as " unimpeded ", " jogging ", " blocking up ", " sealing " as example, then in path list, add the note of similar " (unimpeded) " in " Wei Hailu " three word back, this note shows that this highway section is in unimpeded state, need to prove that the note that adds can indicate with the font that is different from the highway section title.In like manner, can behind " Huang Po North Road " four words, add the note of " (jogging) ", at the note that adds the note of " (blocking up) ", interpolation " (sealing) " behind " Tibet Zhong Lu " four words behind " people main road " four words.Certainly, if do not get access to Real-time Traffic Information corresponding to " Wusheng road ", add note after can noting be used in " Wusheng road " three words this moment, do not add note and then be defaulted as the Real-time Traffic Information that does not get access to this highway section.
Need to prove that the above-mentioned dual mode that indicates the Real-time Road situation in each highway section in path list can use separately, also can be combined with, and can arrange as required.In other embodiments, also can adopt other mode to indicate, other marking modes can also be attached in the above-mentioned dual mode.
Because guiding comprises steering map in the interface, the Real-time Road situation that therefore indicates each highway section of described path of navigation in the guiding interface comprises: the Real-time Road situation that indicates each highway section of described path of navigation in described steering map.Particularly, the Real-time Road situation that indicates each highway section of described path of navigation in described steering map comprises: each highway section that will be drawn on the described path of navigation in the described steering map shows with different colours, and the shown color in highway section is corresponding with the Real-time Traffic Information in this highway section.For instance, can be in conjunction with Fig. 2, suppose still to get access to each highway section " Wei Hailu ", " Huang Po North Road ", " people main road ", the Real-time Traffic Information of " Tibet Zhong Lu " shows that respectively the Real-time Road state in highway section is " unimpeded ", " jogging ", " block up ", " sealing " is example, then in steering map, the highway section a-b that will represent " Wei Hailu " is plotted as green lines (green expression is unimpeded), the highway section b-c that will represent " Huang Po North Road " is plotted as yellow lines (yellow expression jogging), will represent that the highway section c-d in " people main road " is plotted as red lines (red expression is blocked up), to represent that the highway section d-e of " Tibet Zhong Lu " is plotted as the lines (grey represents road closed) of grey.So, can be intuitively, clearly the Real-time Road situation with each highway section of path of navigation is shown on the described steering map.
