<p>The present invention relates to an apparatus which marks, during nighttime travel, a temporary driveway behind transportation means such as two-wheeled vehicles including bicycles, electric wheelchairs, etc. for human use, to thereby ensure the safety of users. In detail, the apparatus of the present invention comprises: a laser-emitting module which forms luminous lines spaced apart from each other by a predetermined distance on the road beside or behind transportation means; a power supply module which supplies power to the laser-emitting module; an external housing which accommodates the laser-emitting module; and a fixing module which fixes the external housing to a transportation vehicle. The apparatus of the present invention has the laser-emitting module which marks a temporary driveway line (guideline) behind transportation vehicles such as two-wheeled vehicles including bicycles, wheelchairs, etc. The laser-emitting module enables the transportation vehicle to form a temporary driveway line by itself during nighttime travel, thus enabling the driver of the vehicle traveling behind the transportation vehicle to easily recognize the distance from the transportation vehicle traveling ahead, and ensuring the safety of a driver in the transportation vehicle.</p> |
