Description

Method and device for displaying traffic information

technical field

The invention relates to the field of navigation, in particular to a method and device for displaying traffic information on an electronic map.

Background technique

The location service terminal refers to the device itself that has various location-related functions or the device provides location services and related functions to users through remote online methods. The location service terminal can be a computer, a mobile phone, a navigation device, etc. Taking a navigation device as an example, its working principle is that the navigation device determines the location coordinates of a specific location, and matches them with the location coordinates recorded in the electronic map stored by itself. To determine the exact position of the navigation object equipped with the navigation device in the electronic map. The navigation device can be a vehicle-mounted terminal, a portable navigator, a mobile phone terminal, and the like. Navigation objects can be vehicles, pedestrians, etc. After the user sets the starting point and the destination, the navigation device will calculate the navigation route according to the electronic map data stored in itself, and guide the user according to the calculated navigation route. Electronic map is a new type of map formed in the 1980s by using digital map drawing technology. The electronic map is a visualization product that displays map data with various multimedia based on the digital map. Electronic maps can be stored on digital storage media, such as floppy disks, hard disks, MOs, CD-ROMs, DVD-ROMs, etc. Electronic maps can be displayed on computers, mobile phones, navigators, or other devices that can load electronic maps. The electronic map is dynamic and can be operated interactively, and can also be printed out to paper at any time. All electronic maps have an operation interface. Electronic maps are generally connected to databases for query and spatial analysis. Electronic map involves digital map drawing technology, geographic information system, computer graphics, multimedia technology and network technology and other modern high-tech. With the development of electronic map technology, in recent years, the display of traffic information such as traffic events and traffic conditions can be realized on the electronic map.

However, during the navigation process, the user's main attention is on the traffic information on the navigation path, and he does not pay attention to the traffic information outside the navigation path. Displaying the traffic information on the electronic map makes the traffic information and the electronic map information confuse together. If it is not clear enough, it will greatly affect the user's acceptance of traffic information.
