<P>PROBLEM TO BE SOLVED: To provide a self-light emission type speed hump, simply informing a driver of a location of a speed hump in the case of a dark environment such as nighttime, and allowing the driver to surely decrease the operating speed with a margin in passing, so that shock from the road surface is decreased to give no shock to a passenger and baggages, and drive a car with relief. <P>SOLUTION: A self-light emission type road rack not projected on the flat surface to be flat is embedded in both sides of the flat surface of the speed hump. The self-light emission type road tack is an LED flickering light emission type incorporating a day/night sensor. In the case of a dark environment such as nighttime using the invention, the self-light emission type road tack automatically flickers and emits light according to the incorporated day/night sensor, so that the driver can be simply informed of the location of the speed hump. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
