In the related art, a navigation electronic map is usually pre-installed in a terminal, and then the traffic information is acquired from the TMC server library through a network, and then the acquired traffic information is matched with the electronic map for display. However, the data volume of the real-time traffic data searched, acquired, and transmitted from the TMC server is particularly large, so that the display speed on the display interface of the terminal is slow. In view of the above problems, embodiments of the present application provide a method for displaying real-time traffic data, which can improve transmission and display speeds of real-time traffic data. The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart illustrating a method for transmitting and displaying real-time traffic data according to an embodiment of the present application.
Referring to fig. 1, the method for transmitting and displaying real-time traffic data includes:
and step S110, acquiring the road of the traffic information channel TMC data to be displayed.
The terminal can obtain the road to be displayed with TMC data. The road on which the TMC data is to be displayed can be a road in a terminal display interface; the upper road may include the road in the terminal display interface, or the lower road may include the road in the terminal display interface, or the upper road and the lower road may include the road in the terminal display interface.
The terminal acquires roads in a map in a display interface, and the roads can be acquired by adopting a related map technology and an image recognition technology, and the scheme of the embodiment of the application is not limited.
And step S120, merging the roads to form a road sequence.
The terminal can optimize and combine the acquired roads according to the road connectivity to form a road sequence. For example, the intersection relationship of each intersection is detected, and roads having no intersection are merged to obtain a plurality of different road sequences.
Step S130, the road sequence is transmitted to the TMC server, and the TMC data corresponding to the road sequence returned from the TMC server is obtained.
After the terminal transmits the road sequence to the TMC server, the TMC server searches the TMC data corresponding to the road sequence according to the received road sequence and returns the TMC data to the terminal, and the terminal obtains the TMC data corresponding to the road sequence returned from the TMC server.
Step S140, the TMC data is displayed on the map.
And the terminal displays the TMC data on an electronic map in a terminal display interface, so that a user can know the latest real-time traffic data. The TMC data can be displayed on the map by using the existing related technology, and the embodiment of the present application is not limited.
It can be seen from the embodiment that the technical scheme of the application can obtain the road of the traffic information channel TMC data to be displayed; and then merging the roads to form a road sequence, then obtaining TMC data corresponding to the road sequence in a targeted manner through a TMC server, and displaying the obtained TMC data on a map. Therefore, the roads are combined in advance, so that the roads can be simplified, the data search amount in the TMC server is reduced, and the real-time traffic data can be displayed on the map quickly.
Fig. 2 is a flowchart illustrating a method for transmitting and displaying real-time traffic data according to an embodiment of the present application. The embodiment takes the road on which the TMC data is to be displayed as the road in the terminal display interface as an example but is not limited thereto.
Referring to fig. 2, the method for transmitting and displaying real-time traffic data includes:
and step S210, acquiring a road in the terminal display interface.
The display interface can be a display interface of the terminal. In one embodiment, the terminal may be, but is not limited to, various personal computers, laptops, smartphones, tablets, navigation devices, and portable wearable devices. It is understood that the size of the display interface of each terminal is the same or different when the user views the road using the terminal. Namely, the roads in the corresponding range are displayed according to the actual size of the terminal display interface.
When the display screen of the terminal is dragged back and forth or zoomed to view, the road of the display interface is correspondingly changed, and in one embodiment, only the road displayed in the display interface can be acquired. By the design, loading or obtaining of roads outside the display interface can be avoided, the number of the roads is reduced, and data are searched for the TMC server only by aiming at the roads displayed in the display interface, so that the search amount is reduced, and the display speed of the TMC data on the map is improved.
The terminal acquires roads in a map in a display interface, and the roads can be acquired by adopting a related map technology and an image recognition technology, and the scheme of the embodiment of the application is not limited.
And step S220, optimizing and combining the roads according to the road connectivity to form a road sequence.
The terminal can merge the roads in the terminal display interface, for example, optimally merge the roads according to the road connectivity. For example, merging may be performed according to the direction and intersection relationship of each road, and roads in the same direction and without intersections are further merged and simplified, and each merged and simplified road has a unique road sequence. It will be appreciated that by merging the links, a plurality of different link sequences may be formed.
Step S230, transmitting the road sequence to the TMC server, and obtaining TMC data corresponding to the road sequence returned from the TMC server.
TMC (Traffic Message Channel) technology is used to broadcast instant Traffic and weather advisories. By transmitting the road sequence to the TMC server, the TMC server acquires TMC data of the corresponding road in real time according to the road sequence, that is, acquires real-time traffic data of the corresponding road sequence. In one embodiment, the terminal and the TMC server establish a wireless connection through a wireless network. The terminal transmits the road sequence to the TMC server through the wireless network, and the TMC server acquires corresponding TMC data according to the road sequence and transmits the TMC data to the terminal.
Step S240, the TMC data is displayed on the map.
And the terminal displays the TMC data corresponding to the received road sequence on the electronic map. The TMC data and the road sequence are mutually corresponding, and the returned TMC data is displayed on the corresponding road series on the electronic map, so that the latest real-time traffic road condition is displayed for the user.
According to the technical scheme, the road displayed in the terminal display interface is selected, the road in the display interface is combined in advance to obtain different road sequences, TMC data corresponding to the road sequences are obtained in a targeted mode through the TMC server, and the TMC data are displayed on the map. By the design, on one hand, the real-time traffic data is searched only for the road in the display interface, so that the data searching amount is reduced; on the other hand, roads in the same direction including multiple roads are merged by merging the roads in the display interface in advance, so that the roads are simplified, the data search amount is further reduced, and the real-time traffic data can be displayed quickly.
Fig. 3 is another flow chart of a method for transmitting and displaying real-time traffic data according to an embodiment of the present disclosure. The embodiment takes the road on which the TMC data is to be displayed as the road in the terminal display interface and the upper road of the road as examples but is not limited thereto.
According to the technical scheme, how to search the real-time traffic data to be displayed is provided, the real-time traffic data to be displayed is optimized, reduced and searched for the TMC server in advance according to road connectivity, the searching amount in the TMC database is small, the TMC database only transmits the needed TMC data to the terminal, the data transmission amount is reduced, and the display speed is high.
Referring to fig. 3, the method for transmitting and displaying real-time traffic data of the embodiment includes:
step S310, acquiring a road in the terminal display interface.
In this step, all the roads in the terminal display interface are acquired, and this step may refer to the description of step S210, which is not described herein again.
Step S320, an upper road of the road in the terminal display interface is acquired.
In the related art, map data is generally hierarchically processed in order to facilitate management and tracking of the data. Specifically, the map data can be divided into a plurality of data levels from top to bottom, one upper layer data can correspond to a plurality of lower layer data, and each layer expresses the communication characteristics of different roads. Different scales may correspond to different data levels. And inquiring the data hierarchy corresponding to the scaling in the pre-stored data hierarchy according to the scaling input by the user. When the data hierarchy in the data hierarchy is sorted by arabic numbers, layer 1 may represent the top layer data, and layer 2, layer 3, and … … are arranged sequentially downward. When the scaling is a reduction scale, the lower the reduction scale, the higher the corresponding data level, for example, the data level corresponding to the reduction scale of 20% of the normal display size is higher than the data level corresponding to the reduction scale of 50% of the normal display size. When the zoom-in scale is an enlargement scale, the larger the enlargement scale, the lower the corresponding data level, for example, the data level corresponding to the enlargement scale of 2 times the normal display size is lower than the data level corresponding to the enlargement scale of 1 time the normal display size.
In one embodiment, according to the scaling of the display interface, determining the corresponding data level of the road in the data hierarchical structure; loading the Nth layer of data of a data level corresponding to the display interface, and synchronously loading at least one layer of data above the Nth layer of data containing the display interface, wherein N is a positive integer greater than 1.
In the embodiment, on the basis of acquiring the current road, the road data of the upper road of the current road is acquired from the map database and used for searching the real-time traffic data, so that the real-time traffic data of the upper road can be searched in advance, and when a user subsequently moves the screen or zooms the screen to the upper road of the current road through fingers, the real-time traffic data of the upper road can be rapidly displayed, the waiting time is shortened, and the user experience is improved. Generally, the road data of the upper road is relatively small.
It should be noted that, in this embodiment, the road in the display interface of the acquisition terminal and the upper road of the road in the display interface of the acquisition terminal are taken as an example for illustration, but not limited to this, and the road in the display interface of the acquisition terminal and the lower road of the road in the display interface of the acquisition terminal may also be taken as the road in the display interface of the acquisition terminal; or acquiring a road in the terminal display interface, and acquiring an upper road and a lower road of the road in the terminal display interface. Therefore, the real-time traffic data of the upper road or the lower road is searched in advance, so that the corresponding real-time traffic data can be rapidly displayed when a user opens the upper road or the lower road, the waiting time is shortened, and the user experience is improved.
Step S330, merging the roads without intersections to obtain a plurality of different road sequences.
In this step, the roads may be optimized and combined according to the road connectivity to form a road sequence. For example, the intersection relationship of each intersection can be detected, and roads without intersections can be merged to obtain a plurality of different road sequences. For example, the intersection may be divided into three intersections, and the roads at the intersection above three branches may be merged, and the roads at the intersection below three branches may not be merged. The three-branch road junction comprises at least three roads which are communicated, and the roads below the three-branch road junction comprise two-branch road junctions, straight roads and the like. Roads at intersections above the three-branch intersection include four-branch intersection roads, five-branch intersection roads and the like. For example, roads that go back and forth in two directions and have no intersection may be merged into one road, multiple roads may be merged into one road, and the like. The combined design enables the road optimization to be reduced, thereby simplifying the road data, further reducing the data searching amount, and accelerating the display of the real-time traffic data.
Step S340, the road sequence is transmitted to a TMC server, and TMC data corresponding to the road sequence is obtained.
It can be understood that by merging the roads, the data amount of the roads can be reduced, so that the data lookup amount is reduced. In one embodiment, the map database of the TMC server may store map data obtained by gridding and dividing road data in the same area. Note that the map data stored in the map database of the TMC server may not be divided into grids. When the road sequence is transmitted to the TMC server, the TMC server can find the road in the map data corresponding to the server according to the road series and find the corresponding TMC data. Therefore, the data transmitted to the TMC server by the terminal is optimized and reduced, so that the data searching amount of the TMC server is reduced, the time for acquiring the real-time traffic data is shortened, and the display of the real-time traffic data can be accelerated.
And step S350, displaying the TMC data corresponding to the received road sequence on the electronic map.
And the terminal displays the TMC data corresponding to the received road sequence on the electronic map. Fig. 4 may be a schematic view illustrating displaying TMC data on a map of a terminal interface according to an embodiment of the present application. That is, after the terminal obtains the TMC data corresponding to the road sequence, the TMC data is correspondingly displayed on the road series of the electronic map, so that the latest real-time traffic road condition is displayed for the user, and the user can obtain the real-time traffic data in time. Further, as shown in fig. 4, the user may also click a function menu for acquiring TMC detail information in the display interface, so that more detailed TMC information is further displayed.
In summary, in the embodiment of the present application, the roads displayed in the terminal display interface are selected first, and the roads in the display interface are further merged, so that the data search amount in the TMC server can be reduced, the search time can be shortened, and the display speed of the returned TMC data on the map can be increased. In addition, the data of the upper road can be acquired while the road in the current display interface of the user is acquired, so that when the user wants to browse the TMC data of the upper road, the TMC data of the upper road can be quickly displayed, and the use experience of the user can be greatly improved.
It should be noted that the embodiment takes the road on which the TMC data is to be displayed as the road in the terminal display interface and the upper layer road of the road as examples but is not limited thereto. The embodiment of the application can also acquire the road in the terminal display interface and the lower road of the road in the terminal display interface; or acquiring a road in the terminal display interface, and acquiring an upper road and a lower road of the road in the terminal display interface. Therefore, the corresponding real-time traffic data can be rapidly displayed when the user opens the upper layer road or the lower layer road, so that the waiting time is shortened, and the user experience is improved.
