A road generator according to an embodiment of the present invention includes an elevation rod which is lowered by the weight of a driving vehicle; a gear set which converts linear delivery force of the elevation rod into a rotary force; a generator which receives the rotary force from the gear set and generates electricity; and a driving force accumulating tool which is connected to the gear set, accumulates the rotary force generated when the elevation rod is lowered, and delivers the accumulated rotary force to the generator. The road generator according to the present invention shows very high generation efficiency since the road generator applies the rotary force to the generator to generate electricity not only while an elevation block is lowered by the weight of a vehicle but also while the elevation block is elevated to the original position. Therefore, the road generator has high generation efficiency by generating current and enhances usability because the road generator can generate for a predetermined time after the vehicle passes. |
