Lane guidance display method, and navigation device and recording medium for realizing the method

摘要

Based on searched route information and map data, a target intersection for guidance is specified (S11). For the specified target intersection, lane data regarding the number of lanes and lane control of roads being connected thereto is read, and then recommended lane information which indicates which lane to take when entering the target intersection and to exit therefrom is generated (S12). Based on information about the target intersection and the lane data, generated is a simplified intersection image of the target intersection for lane guidance (S13). Based on the recommended lane information, a running path which passes through the recommended lanes for entering into and exiting from the target intersection is generated, and is combined with the intersection image (S14). Then, lane guidance information for displaying the resultant intersection image is outputted with a predetermined timing (S15). As such, guidance can be visually made on a screen indicating which lanes to take to enter into and exit from the intersection.
