The present invention relates to a navigation system, and more particularly, to a geographic information guidance system and method for providing a route guidance to a destination desired by a user.
In general, a navigation system (hereinafter, referred to as a user terminal) is a system that provides information for driving a vehicle such as a vehicle by using a satellite and is also called an automatic navigation system.
The user terminal receives a predetermined data from a GPS satellite floating on the earth using a global positioning system (GPS) receiver, and calculates its position based on the received data.
Helping the driver to inform the user of the current location of the vehicle based on his location information (Location), calculate the route to the desired destination (Routing), and guide the user according to the route. Various information can be provided.
That is, by receiving signals including latitude and longitude information from GPS satellites, the user's location is calculated and output, and map-matching of terrain, roads, buildings, etc. to geographical information arranged according to latitude and longitude It guides you from your current location to the destination you want.
The user terminal performs a road guide while displaying a moving route to a destination at a fixed scale on a display device, and informs the direction of movement at an intersection point on the road by an image or a voice.
However, as roads are expanded or expanded due to the increase in vehicles, intersections such as highway interchanges, bridges, and elevated roads are increasing, resulting in improper scaling of maps at many intersections. Due to positioning errors, it is sometimes difficult to determine the correct approach.
In addition, when driving while viewing the geographic information provided by the existing user terminal, a user may confuse the access road and erroneously enter or pass at a complicated intersection. Even if you are entering the right driveway, the user may be a factor that disturbs safe driving, such as being embarrassed by doubt about entering the path.
SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art as described above, and an object thereof is to provide a new way crossing driving guide for safer driving at an intersection on a route.
