AUTOMATIC TRAVELING ROAD AND AUTOMATIC TRAVELING SYSTEM

摘要

PROBLEM TO BE SOLVED: To ensure the fail-safe automatic travel on curved roads and the automatic travel in diverging and merging sections as well by not providing the diverging sections, merging sections and sharply curving sections of travel lanes with travel lane guiding marks but providing only the straight lanes or the travel lane drawing gentle curves with these marks. SOLUTION: The travel lanes where the rightward extending straight road intersects with the vertically extending straight road are provided with a first guiding white line 31 along the vertically extending straight road and are provided with a second guiding white line 32 along the rightward extending straight road. The left end of the second guiding white line 32 is parted from the first guiding white line 31 and the merging section (or diverging section) of both roads is not provided with the guiding white lines and is formed as a blank part. The automatic travel by a mark follow-up type automatic traveling device is made to be executed in the straight travel routes and the travel routes of the gentle curves. The automatic travel by a map reference type automatic travel device is made to be executed in the sharply curving sections, diverging road sections and merging road sections where the detection of the travel guide marks are difficult.
