<p><P>PROBLEM TO BE SOLVED: To solve a problem that each of a turn-right vehicle and an opposite side going-straight vehicle at a crossing point acts under a timing based on a guess work while lacking of a concrete judgment material even if a traffic rule on priority is considered whether or not the own vehicle can go straight as it is or whether or not the own vehicle stops to wait for the opposite vehicle to go, and further pedestrians near around also can take action only by prospective judgment, so that if a current intention of the advancing vehicle can be read from its front side, additional judgment material on action is added to improve a traffic safety in driving operation. <P>SOLUTION: A signal box for lighting and displaying a brake operation is connected to a license plate at the front surface of a vehicle and this box is fixed to and installed at the vehicle together with the license plate. The signal box shows a clear lighting and displaying of Kana letters of "brake" at its surface when a driver steps on the brake, and clearly expresses against the pedestrians that the vehicle intends to stop or slow down. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
