The first embodiment of the present application will be described in detail below with reference to fig. 1. The method comprises the following steps:

step S101: and acquiring original traffic network data.

This step is used to obtain the original traffic network data.

The original traffic network data adopts a national standard network triple (road id, map breadth and direction). In the prior art, internet map providers (such as providers of various navigation maps APP) use such raw traffic network data.

Step S102: and acquiring road section data of a traffic network and road link data of a map according to the original traffic network data.

The step is used for obtaining road section data of a traffic network and road link data of an internet map according to the original traffic network data.

In this embodiment, a solution is provided for solving a problem that the traffic industry, as one of the traditional industries, has a lot of data collected by incomplete equipment, but the data are often difficult to be utilized when making a decision, in which unit road network information such as standard definition and high definition map road network information, traffic police, road and government offices and the like are mapped into a set of unified road network structure data organized according to road segments, and other traffic-related dynamic and static data are processed on the basis of the road segments. The road section (RID) refers to a basic road section in the brain of a city, and the road section is determined according to important intersections of important roads. In the traffic field, important roads and intersections are rarely changed, the change frequency is far lower than that of branch roads, and the branch roads are not important concerns for analyzing traffic laws.

In this embodiment, the traffic network adopts the above solution. The Link refers to a basic road segment which is used for issuing traffic information by adopting axf + in an internet map. The internet map can be various maps APP commonly used in the prior art.

In this embodiment, quarterly edition national standard triple data is taken, and a city brain basic road network database of a certain city is formed through manual or tool processing according to data manufacturing and coding specifications, wherein the city brain basic road network database includes manufacturing of an RID road section, and a relation table of an RID and a triple is generated.

The acquiring of the road data of the traffic network and the road link data of the internet map according to the original traffic network data comprises the following steps:

and extracting road section information aiming at the road section object from the national standard road network information.

The original traffic network data adopts a national standard network triple (road id, map width and direction), and road section information in the traffic network is determined according to road identification information, map width information and direction information included in the original traffic network data.

The method for obtaining the traffic data further comprises the step of constructing the corresponding relation between the road section data and the road link data.

This step is used to construct a correspondence between the link data and the road link data.

For example, table 1 below gives the matching relationship between the link and the road link.

TABLE 1 matching Table of road segments (RID) and Link links (Link)

Step S103: and acquiring traffic data mounted on a road chain corresponding to the road chain data.

The step is used for obtaining the internet traffic data mounted on the road chain corresponding to the road chain data.

traffic speed information;

traffic flow information;

and (4) traffic track information.

Step S104: and acquiring the traffic data mounted on the road section corresponding to the road section data according to the traffic data mounted on the road chain corresponding to the road chain data and the corresponding relation between the road section data and the road chain data.

The step is used for obtaining the traffic data mounted on the road section corresponding to the road section data according to the internet traffic data mounted on the road chain corresponding to the road chain data and the corresponding relation between the road section data and the road chain data.

The location service comprises navigation, traffic route guidance, alarm prompt of a traffic accident place, map information display and the like.

The traffic guidance is to guide the running of vehicles according to traffic road conditions so as to avoid congestion, thereby improving the traffic efficiency of cities.

The traffic object refers to various traffic entities, such as road sections, intersections, junctions, traffic facilities, traffic equipment and the like.

The traffic accident occurrence place or the traffic jam place is provided with the warning prompt for the traffic vehicles, so that the vehicles can avoid the accident occurrence place, and the urban traffic efficiency is improved.

The obtaining the traffic data mounted on the road section corresponding to the road section data according to the internet traffic data mounted on the road chain corresponding to the road chain data and the corresponding relationship between the road section data and the road chain data includes:

performing data conversion on internet data on a road link corresponding to the road link data contained in a road section corresponding to the road section data to obtain traffic data mounted on the road section corresponding to the road section data;

For example, according to the correspondence between the Link data and the road Link data, it is determined that the Link RID1 corresponding to the Link data contains the Link links 1 and Link2 corresponding to the Link data;

the Link1 and Link2 represent traffic information using internet data, and can convert the traffic information represented by the internet data into traffic information on links of a traffic network.

Through these steps, conventional internet map providers, such as link traffic information expressed using internet data in various navigation APPs, are converted into link traffic information related in the solution.

obtaining a mapping relation between a first intersection of a traffic network and a second intersection of an internet map provider according to an intersection identification of the traffic network, an intersection identification of an internet map and a region code corresponding to the traffic network;

See table 3, which shows the mapping of RID and client system segments.

TABLE 3 mapping of RIDs and client system road segments

Through these steps, the transportation facility information expressed in the client system using the client data is converted into the transportation facility information related in the solution.

In the real traffic management, the equipment plays an important role, the traffic equipment is the main acquisition means of traffic information, and the traffic facilities are the main means for formulating traffic rules.

The traffic equipment comprises various traffic police equipment such as signal lamps, signal machines, bayonets, electric police, microwaves, coils, cameras and induction screens.

The traffic facilities refer to various traffic police facilities such as marks, marked lines, zebra crossings, signs, posts, bus stations, parking lots and the like in roads.

Similarly, the traffic device and lane mapping relationship is shown in table 8 below.

The lanes are divided in road sections according to lane indicators to separate traffic flows of co-current traffic. The space position of the lane is represented by the central line of the lane, and the lane is interrupted at the position where the number of lanes changes and the virtual-solid line of the lane boundary changes.

Fig. 2 is a flowchart of an application example of a traffic data obtaining method according to the present embodiment.

The application example is particularly used for uniformly expressing road data by using road sections and intersections in a traffic data fusion engine. The link can be mapped from the road section, and then data such as real-time road conditions, historical flow, vehicle speed, track and the like can be obtained. Since links in the internet map change frequently, the mapping relationship from the road section to the internet map link needs to be updated regularly.

The key points of the flow chart are explained as follows:

(1) and updating the relation table of the RID and the triples according to the quarters, and generating the RID data of the new version and the data of the RID and the triples according to the relation data of the original triples and the RID when the new triples come.
