Description

How to provide traffic information ahead of the vehicle{METHOD FOR PROVIDING FRONT TRAFFIC INFORMATION OF VEHICLE}

The present invention relates to a technique for providing forward traffic information to trailing vehicles, and more particularly, providing information on the average driving speed of the front side as a number display for each lane when the vehicle is driving on the road. It relates to a method of providing traffic information in front of a vehicle that can be done.

As is known, in the existing traffic information providing model, the vehicle flow (vehicle speed) in front of the road is detected using GPS, and the detected vehicle flow of the road ahead is displayed on the navigation display panel in the color of the entire road (display ).

Here, the expression of the vehicle flow in front of the road is green when the vehicle flow is smooth (e.g., a vehicle speed of 60 km or more), and when the vehicle flow is congested (e.g., a vehicle speed is 20 km or less), the corresponding road area The entire road area can be visually expressed in red, and when the vehicle flow is smooth and normal between traffic jams, the entire road area can be visually expressed in orange.

However, in the case of the vehicle speed on the road ahead, although the average driving speed of vehicles in all lanes (e.g., three lanes one way, four lanes one way, five lanes one way, etc.) Since the vehicle flow is visually expressed in color, there is a problem that the driver cannot find a lane that is slightly less congested among several lanes.
