For the public traffic information that is stored in Figure 12 structure, when providing server 100 to receive new information from transit information, corresponding information just is updated.
Alternatively, all data that control engine 5 will not be received from TPEG-PTI demoder 3 all are stored in storer 4, but can only select and store about the data near the station of current location, for example being positioned at the data at the station of 1 kilometer radius, this can be found by GPS module 8.The reason of doing like this is to utilize expeditiously the storer of finite capacity by the public traffic information that the 200 user's most probables of storage terminal only need.
Received public traffic information is stored as described above if the user is via input block 9 request public traffic informations, control engine 5 searching storages 4 and drop on from by---for example 1 kilometer---interior station of detected current location one preset distance of GPS module 8 to seek its position based on longitude and latitude, and with tabular form, these stations are presented on LCD panel 7 as shown in figure 13 at step S131.In this case, control engine 5 suitable driving signal is put on lcd driver 6 to show the station list.
When the user selects a station via the list of input block 9 on being presented at screen, control engine 5 obtain about be stored in as shown in figure 12 in storer 4 about the information of prediction time of arrival (or being ranked time of arrival) of this every route in station and at step S132, the identification information of this information in company with route is presented on screen together.By handling another options button or shifting bond(s)s via input block 9, different information---for the current location of rear one class of bus of every the route storage in this station can be shown.
In the situation that has the nonvolatile memory (hereinafter being referred to as " memory storage ") that comprises electronic chart in terminal 200, when choosing the station under step S131 has shown the state at station, can be from memory storage read electric map around at this station necessary part (can be presented at the zone on LCD panel 7) and can via driver 6, it be presented on LCD panel 7 at step S131-1.Indicated a particular graphic symbol on current location, and indicated information and particular graphic symbol about the description of choosing the station on the interchange of position of choosing.When pressing acknowledgement key under having shown the state of selecting station part on every side in the electronic chart, just show the information about the route that passes through this station.
Shown on screen as the user when selecting a route under the state of list of routes, control engine 5 and read the shape information of this route and about the information at the station that belongs to this route from storer 4 and/or single memory, and at step S133, it is presented on screen.By this demonstration, the user just can determine whether this route makes the user can arrive required destination.In this case, if be provided with memory storage, control engine 5 and indicate information about the shape of this route on electronic chart.When the user inputs " details " or " selection " under above-mentioned state, control engine 5 around amplifying in itinerary map at selected station based on shown shape information part and step S133-1 with the partial display that amplifies on screen.When this part of itinerary map is shown in detail, the information (station ID or node ID) about reading in the middle of the information of choosing route by selected station about rear one class of motorbus current location from be stored in storer 4 is read out, and will be presented at such as the special icon of motorbus icon etc. on screen on screen on this current location, so that the user can know by vision the position of motorbus.
Among the embodiment that provides server 100 to send the public traffic information as shown in Fig. 7 A and 7B from transit information (value in being recorded in the message report type field is in the situation of pti27_4), control data that engine 5 will receive from TPEG-PTI demoder 3 and be stored in storer 4 with the structure of Figure 14.Figure 14 only illustrates an example of data store organisation.
Correspondingly, if other information element of the information element that provides server 100 to provide to be different from data store organisation shown in Figure 14 from transit information, structuring and store these other elements in storer 4.In " the speed-shifting field " of Figure 14, be negative ("-") value of record in the situation of low speed in the speed of corresponding interval, for example-1; To record just ("+") value, for example+1 in situation at a high speed in speed; And do not have velocity variations maybe can't determine the situation of velocity variations in the record 0 value.Above-mentioned value is the value that provides server 100 to provide by transit information.In the situation that can't discovery speed changes, can assign and use the value different from value in the situation that can't discovery speed changes, for example be worth 2.
Similar to the aforementioned embodiment, in the present embodiment, terminal 200 has the shape information of longitude and latitude information and each circuit at each station in independent information table.Being that the situation that the information that provides server 100 to provide from transmission information builds is provided at information table, it can being stored in storer 4, is perhaps in the situation that builds when making terminal 200 at information table, it can be embedded in independent storer.
For the public traffic information in the structure that is stored in Figure 14, when providing server 100 to receive new information from transit information, corresponding information just is updated.
Alternatively, controlling engine 5 is not that all data that will be received from TPEG-PTI demoder 3 all are stored in storer 4, but only select and store data about near the station current location, and for example dropping on the station within the 1km radius, this can be found by GPS module 8.
Under the state of the public traffic information that arrives at storing received as described above, when the user asks public traffic information via input block 9, its option can be displayed on LCD panel 7, as shown in figure 15 at step S151 for the public transportation information related menu that the user selects.When from shown menu setecting road wire size search terms, provide an input window.When at step S152 when input window has been inputted the road wire size thus, control engine 5 searching storages 4, obtain the information of (or being ranked) running time that dopes about each station for respective routes number, these information are stored as shown in Figure 14, and at step S153, this information are presented on screen with station sign title.In this case, as shown in figure 14, comprise current location one preset distance that is positioned at from being detected by GPS module 8 for the route part of---for example 1km---can show longitude and the latitude at each station.Alternatively, in the situation that is provided with the memory storage that comprises electronic chart, the shape of selected route is indicated on electronic chart.In this state, the user can obtain with the shifting bond(s) of input block 9 information about the station at another non-indication interval.
If the user is via the part of input window input road wire size, a plurality of road wire size may with input number coupling.In this case, control engine 5 in the middle of the public traffic information of storage as shown in Figure 14 search all have the road wire size of matching number, and at step S152-1, the road wire size that finds is enumerated on screen with the identification information of each route.When having selected a route in the middle of the route of enumerating, time showing is travelled on screen in prediction (or being ranked) interval that will belong to as described above every station of this route at step S153.
For deal with step S151 do not have to select " search of road wire size " but from public transportation information related menu selected the situation of station relevant search, control the public traffic information of engine 5 from be stored in Figure 14 structure and search for station relevant field 141, and be respectively the route structure table by each station.For example, if station A detected in all three route L1, L2 and L3, build the table that these three route L1, L2 and L3 is mapped to station A.This table is used for promptly will being shown to the user by the route at this station when finding the station searching for by the station.
