Then various researches on hump have been conclude as a traffic calming measure in community road. In this research, the effect when humps combined with chokers set up on the community road was examined. In addition, comparison which paid its attention to form by installing the hump (a trapezoid hump and an arch hump) of different form in the same area was performed, and hump spread possibility was verified. As a result, arch hump has a higher speed inhibiting effect than trapezoid hump. In addition, about vibration and the noise, the trapezoid hump turned out that influence by the hump setting was smaller than the arch hump. There is a possibility for hump to increase in the future from the installation of the adequate shape.
