Problems solved by technology

The disadvantages of the solution are: on the one hand, the main work is concentrated on the server side, which puts a lot of pressure on the server side; Reduced user experience effect
[0008] In this solution, the client needs to carry a complex and huge map, often hundreds of megabytes, which makes it inconvenient to store and download the map, and also brings many problems such as map update and upgrade, which makes the maintenance cost very high

Embodiment 1

[0057] figure 1 It is a flow chart of a method in the embodiment of the present invention, which is used for displaying road conditions on a terminal. The terminal stores road data, and the road data includes the circumscribed rectangle information of the road, and the first-type coordinates corresponding to the first-type designated points of the road , the road is composed of road segments; including the following steps:

[0058] S101: receiving road condition data of road sections;

[0059] S102: Obtain a road to be displayed that intersects the road condition query area from the road data according to the input road condition query area and the circumscribing rectangle information of the road in the road data;

[0060] S103: From the road condition data, obtain the road condition state of the road section constituting the road to be displayed;

[0061] S104: Draw the road to be displayed according to the first type of coordinates of the first type of designated point on th...

Embodiment 2

[0064] figure 2 It is a schematic flow diagram of the second method of the present invention, including:

[0065] S201: Pre-store road data. In this embodiment, the road data needs to be stored in advance on the terminal, that is, the client. The storage may be stored by downloading and / or directly preinstalled. If it is the way of downloading, since the volume of the road data is very small, it can be downloaded every time the terminal initializes the program to obtain the latest road data, which is very important for the huge maps in the prior art. unimaginable. Of course, it can also be downloaded after the road data version is updated, or only the incremental package can be downloaded.

[0066] In this embodiment, before the road data is stored on the terminal (or client), a preprocessing process is required to obtain the road data. The preprocessing process includes the following steps:

[0067] First, select several roads from the map, for example, those roads or ...

Embodiment 3

[0110] Figure 11 It is a schematic diagram of a device according to Embodiment 3 of the present invention, which is used for displaying road conditions on a terminal. The terminal stores road data, and the road data includes the circumscribed rectangle information of the road, and the first type of coordinates corresponding to the first type of designated points on the road. The road is made up of road segments; the device includes:

[0111] a receiving unit 1101, configured to receive road condition data of road sections;

[0112] The road to be displayed acquiring unit 1102 is configured to obtain the road to be displayed intersecting the road condition query area from the road data according to the input road condition query area and the circumscribing rectangle information of the road in the road data;

[0113] a road condition obtaining unit 1103, configured to obtain, from the road condition data, the road condition status of the road sections constituting the road to ...

Abstract

An embodiment of the invention discloses a method used for a terminal to display road conditions, a device used for the terminal to display the road conditions, and equipment. Road data are stored in the terminal, the road data comprise bounding rectangle information of roads and the first kind of coordinates corresponding to the first kind of specified points of the roads, and the roads are composed of sections. The method comprises the following steps of receiving data of the road conditions of the sections; obtaining a road which is to be displayed and intersects a road-condition query region from the road data according to the input road-condition query region and the bounding rectangle information of the roads in the road data; obtaining road-condition states of the sections constituting the road to be displayed from the data of the road conditions; drawing the road to be displayed according to the first kind of coordinates of the first kind of specified points of the road to be displayed; and displaying the road-condition states of the sections constituting the road to be displayed on the road to be displayed. According to the method, the device and the equipment, the road data having a smaller size than an existing map are used, and the function of road-condition displaying is realized on a client. The method, the device and the equipment can be separated from the existing map, and have the advantages of achieving convenient downloading and upgrading.

Description

technical field [0001] The invention relates to the field of traffic information, in particular to a method and device for displaying road conditions on a terminal. Background technique [0002] Traffic / travel information is an important part of building an intelligent transportation system. It can display real-time and predicted road conditions and various travel-related events to end users in the form of graphics, text or voice, and provide information for personal travel and traffic scheduling. important references for decision-making. A typical application scenario is: at a certain moment, the user wants to check the current road conditions of a certain road section or area. If the traffic is still smooth, the client (or terminal) can use the client (or terminal) to send a query request to the server to obtain the server's response. information, and display it on the client, so as to understand the road conditions of the road section or area. [0003] An existing techn...
