PROBLEM TO BE SOLVED: To provide a method for forming a bump to decelerate a vehicle in which the execution is facilitated, the execution property is improved, and the execution period is shortened. SOLUTION: In a method for forming a bump for decelerating a vehicle, a part of a rod is raised so as to form a trapezoidal section along the road direction to force deceleration of the vehicle. An inclined body 1 of approximately right triangle in section is fixed with a space longitudinally along the road direction, a pavement material 2 such as asphalt and concrete is filled between perpendicular surfaces 12 of the front and rear inclined bodies 1, and an upper surface 21 of the pavement material 2 is approximately flattened. Because an inclined part of trapezoidal section which is difficult to form is formed using the inclined bodies of approximately right triangle section which can be manufactured in a shop, etc., in advance, no skill is required in the execution, the execution property is improved, and the execution period is shortened. |
