Description

A method for displaying dynamic traffic information road sections and a navigation display

technical field

The invention relates to the field of intelligent traffic information services, in particular to a dynamic traffic information section display method and a navigation display.

Background technique

At present, relatively mature international standards and regional standards for link coding that support dynamic traffic information have been formed in the world. The European Union's TMC (Traffic Message Channel, traffic information channel) standard uses location table/matching table (Location Table/Matching Table) codes to support traffic information; Japan's VICS (Vehicle Information and Communication System, road traffic information communication system ) standard, its VICS Link ID code realizes the support for dynamic traffic information.

my country has released the recommended national standard "Road Coding Rules for Road Traffic Information Services". Currently, the location reference coding system RTIC LR (Realtime Traffic Information of China Location Reference) based on the national standard has been provided in large and medium-sized cities across the country. Real-time traffic information service. RTIC LR coding system supports FM-RTIC real-time traffic information service.

RTIC LR takes the secondary frame as the coding unit, and the roads in each frame are divided into 4 levels, and the maximum coding amount of each level is 4095. Limited by the FM bandwidth, the level and the amount of coding of the RTIC LR coding system are limited. Therefore, only the main roads in the city can be coded for publishing or receiving real-time traffic information.

As shown in Table 1, the existing RTIC LR coding system mainly has four levels.

Table 1. Existing RTIC LR coding system

However, the traffic congestion in various cities in China is becoming more and more serious at present, and users hope to obtain as comprehensive traffic information as possible to guide travel.

Contents of the invention

Embodiments of the present invention provide a dynamic traffic information link display method and a navigation display, which can send more comprehensive traffic information to users for travel guidance.

In order to achieve the above object, embodiments of the present invention adopt the following technical solutions:

On the one hand, a method for displaying dynamic traffic information road sections is provided, which displays road information defined by four levels of China's real-time traffic information location value reference, including:

Analyze the urban road network, and select bypass roads around important roads as road coding objects defined by level 5;

Analyze the urban road network, and select the branch roads around the important points of interest as the road coding objects defined by level 6;

Display the information of the roads defined by the four grades referenced by the position value of the real-time traffic information in China, and the information of the roads defined by the grade 5 and grade 6.

In one aspect, a navigation display is provided, comprising:

The level 5 display module is used to display the information of the road defined by level 5. The road defined by level 5 is obtained by selecting the surrounding detour roads of important roads after analyzing the urban road network;

The level 6 display module is used to display the information of the roads defined by level 6. The roads defined by level 6 are obtained by selecting surrounding branches of important points of interest after analyzing the urban road network.

The dynamic traffic information link display method and the navigation display provided by the embodiment of the present invention expand the grades of the existing RTIC LR, and expand the original 4 grades to 6 grades. When some high-grade roads are congested, grade 5 6. It can provide users with detailed traffic information of surrounding branch roads, so it can provide users with more comprehensive and useful road references, save users' travel time, and reduce users' travel costs.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The method for displaying dynamic traffic information road sections provided by the embodiments of the present invention, as shown in FIG. 1 , includes:

S101. Analyze the urban road network, and select detour roads around important roads as road coding objects defined by level 5.

Specifically, the roads defined by this level 5 also include: branch roads and necessary connecting roads between levels 1-4;

The road categories defined by this level 5 are: township and rural roads;

The range of roads defined by this level 5 is: the city center and connecting roads;

Coverage of roads defined by this class 5: 10% or more.

In addition, the selection principle of roads defined by level 5 may be: select detour roads next to congested expressways, as shown in FIG. 2 .

S102. Analyze the urban road network, and select the branch roads surrounding the important points of interest as road coding objects defined in Level 6.

Specifically, the roads defined in Level 6 also include: necessary connecting roads between Levels 1-5, and roads concerned by important customers;

The road categories defined in this level 6 are: township and rural roads;

The scope of roads defined by this level 6 is: the city center and connecting roads;

Coverage of roads defined by this class 6: 10% or more.

In addition, the selection principle of roads defined by level 6 may be: select a high-level road to a low-level road leading to a point of interest, as shown in FIG. 3 .

S103. Display information of roads defined by four levels of RTIC LR, and information of roads defined by levels 5 and 6.

Further, the roads defined by extension levels 5 and 6 can be transmitted and displayed through the IP channel, which will not affect the existing FM-RTIC.

The road definition of each level of RTIC LR extended by the dynamic traffic information link display method provided in this embodiment can be expressed in Table 2.

For the real-time traffic information service, in addition to the real-time traffic information on the main arterial lines of the city, the traffic information on other secondary arterial lines and branch roads also has a great impact on people's travel. Especially when the main road is controlled or congested, how to choose a smooth branch road to bypass the congested or controlled road is very important to the user.

The dynamic traffic information link display method and the navigation display provided by the embodiment of the present invention expand the grades of the existing RTIC LR, and expand the original 4 grades to 6 grades. When some high-grade roads are congested, grade 5 6. It can provide users with detailed traffic information of surrounding branch roads, so it can provide users with more comprehensive and useful road references, save users' travel time, and reduce users' travel costs.
