PROBLEM TO BE SOLVED: To call driver's attention by forming projecting lines in the direction perpendicular to an advancing direction of a vehicle on a road surface just before a temporary stop and imparting vibration with rhythmical sense to a driver riding across these projecting lines and traveling. SOLUTION: On a road surface 3 just before a place 1 where a vehicle 7 should temporarily stop, substantially parallel projecting lines 5a, 5b, 5c, 5d, 5e... are formed in the direction perpendicular to an advancing direction of the vehicle 7. These projecting lines 5a, 5b, 5c... are disposed at intervals so as to impart vibration with fixed rhythmical sense to a driver of the vehicle 7 riding across the projecting lines 5a, 5b, 5c... and traveling. Then, the driver recognizes that the vehicle 7 approaches a place to be temporarily stopped by feeling comfortable vibration with this fixed rhythmical sense. As a result, the temporary stop is surely urged on the driver and also an effect of preventing sleepiness can be displayed. |
