Problems solved by technology
[0004] Although the existing navigation device can know the traffic situation of the road ahead, when the road ahead is congested, it cannot know how long the road ahead will be congested, that is to say, it cannot judge whether the road ahead will be blocked for 5 minutes or not. 50 minutes, if the traffic jam is only 5 minutes, the user does not need to save time by detour again, if the traffic jam is 50 minutes, the user can consider saving time by detour, but the existing technology cannot know The time when the road ahead is still congested, so the user cannot make an accurate judgment

The invention relates to a time early-warning method for traffic jam and a device thereof. The method comprises the following steps: traffic characteristic parameters of a real-time traffic condition of a first road navigation path are obtained; traffic jam time of the first road navigation path is calculated by the use of the obtained traffic characteristic parameters; and the calculated time is broadcasted. The device comprises an obtaining module used for obtaining the traffic characteristic parameters of the real-time traffic condition of the first road navigation path, a calculation module used for calculating the traffic jam time of the first road navigation path by the use of the traffic characteristic parameters obtained by the obtaining module, and a broadcasting module used for broadcasting the calculated time. The method and the device can be used to forecast traffic jam time of a road ahead.
Description
technical field [0001] The invention relates to the technical field of car navigation, in particular to a method and device for early warning of road congestion time. Background technique [0002] The Global Positioning System (GPS) is already the most basic function built into the personal navigation device known to the public, and is widely used in the personal navigation device in the car. A common function of a personal navigation device is to provide a map data analysis to generate appropriate navigation instructions and display the instructions on the screen of the personal navigation device. This type of personal navigation device is usually fixed on the front dashboard of the vehicle with suction cups or other kinds of fixing elements. [0003] A personal navigation device generally refers to a device that can guide a user to a predetermined destination. Such devices usually have a built-in system that accepts positioning data, such as a GPS receiver, or may only c...
