Embodiment 1

[0029] This embodiment provides a method for updating real-time traffic information, such as figure 1 As shown, the method includes:

[0030] 101. Obtain the latest version of map data.

[0031] 102. Acquire RTIC difference table data of China's real-time traffic information service according to the map data.

[0032] 103. Compile the RTIC difference table data to acquire RTIC data.

[0033] Wherein, the RTIC data is used to update the difference between the current RTIC data and the map data.

[0034] Wherein, said acquisition of China's real-time traffic information service RTIC difference table data according to said map data includes:

[0035] Acquiring road network planning data according to the map data;

[0036] Obtaining an RTIC MT (Matching Table, matching table) code according to the road network planning data, wherein the RTIC MT code includes RTIC MT differential data and RTIC MT total data;

[0037] An RTIC difference table is made according to the RTIC MT co...

Embodiment 2

[0046] This embodiment provides a method for updating real-time traffic information, such as figure 2 As shown, the method includes:

[0047] 201. Acquire the latest version of map data from a map provider.

[0048] 202. According to the obtained map data, update the current version of road network planning to obtain road network planning data.

[0049] For example, road network planning data, such as urban arterial roads, secondary roads, and branch roads, are obtained from the latest version of map data, and the new road network planning data obtained are compared with the current road network planning data to obtain two The difference data of each data is regarded as differential data, and the new road network planning data is sent to the map provider for encoding processing.

[0050] 203. Obtain a new RTIC MT code according to the road network planning data.

[0051] Among them, the RTIC MT code includes RTIC MT differential data and RTIC MT total data, and the RTIC MT...

Embodiment 3

[0062] This embodiment provides a device for updating real-time traffic information, such as image 3 As shown, the device includes:

[0063] The map acquisition module 31 is used to acquire the latest version of map data;

[0064] The difference table acquisition module 32 is used to obtain China's real-time traffic information service RTIC difference table data according to the map data;

[0065] The RTIC data acquisition module 33 is configured to compile the RTIC difference table data and acquire the RTIC data, wherein the RTIC data is used to update the difference between the current RTIC data and the map data.

[0066] Further, such as Figure 4 As shown, the difference table acquisition module 32 includes:

[0067] A road network planning data acquisition unit 321, configured to acquire road network planning data according to the map data;

[0068] A code acquisition unit 322, configured to obtain the MT code of the RTIC matching table according to the road network ...

Abstract

The embodiment of the invention discloses an updating method and a device for real-time traffic information, and relates to the technical field of intelligent traffic information service. The method can solve the problem of poor real time of RTIC (Real-Time Information of China) data and improve user experience. The method comprises the following steps: obtaining map data of the newest version; obtaining difference table data of real-time information of China (RTIC) according to the map data; and compiling the difference table data of RTIC and obtaining RTIC data, wherein the RTIC data are used for updating the different parts of the current RTIC data from the map data. The method and the device are suitable for updating RTIC data in traffic information service.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic information services, in particular to a method and device for updating real-time traffic information. Background technique [0002] With the continuous popularization of Internet applications and the continuous expansion of information service fields, people's travel is increasingly dependent on navigation systems. RTIC (Real-Time Information Of China, China's real-time traffic information service) is a traffic information service suitable for domestic use in China. It can broadcast relevant road traffic conditions in real time and provide comprehensive navigation data information for people's travel. In the implementation process of RTIC, the latest map data is needed as the basic data to realize traffic navigation and road condition broadcasting. Therefore, the real-time performance of map data is very important for end users using navigation services, and directly affects the user'...
