Abstract

The utility model relates to a navigation device capable of displaying traffic lanes, which comprises a CPU unit, a GPS unit, a map database, a vehicle speed sensor, an angular speed sensor, a going straight or turning database providing going straight or turning information and a touch screen. When a complicated intersection in front is an intersection which allows turning left and turning right,but when navigation map data is analyzed, the current navigating instrument divides the intersection into two parts, namely, the first part is a position crossing with the intersection for turning right and the second part is a crossroad; the first part only gives a hint of turning right and the second part gives a hint of turning left, thereby causing users to misunderstand that the intersectiononly allows turning left when seeing the first part. In order to more clearly describe the actual situation of the complicated intersection, the hint of turning left at the second part is also displayed at the first part, so as to avoid misunderstanding. Besides, giving the lane change hint on a multi-lane road in advance can cause the driving to be safer and driving paths to be more reasonable and can prevent violating traffic rules and taking a wrong lane.
