In this paper, we propose an optimum design method for a combined speed hump and pedestrian crossing. This speed hump, with a flat at the top, has circular sections with easement curves at the ends. The height of the speed hump equals that of the sidewalks, and the length of the speed hump and the width of the pedestrian crossing are design variables of the optimum design. The objective of the design is to minimize the maximum acceleration experienced by the driver of a vehicle passing over the speed hump at its design speed. This design is subject to constraints on maximum accelerations at speeds over the design speed so that the driver may be alert to his/her speed. As a result of the optimum design, the optimum cross-sectional profile of the speed hump is obtained. It is cleared that the optimum speed hump is effective in reducing speed of vehicles, and has robust on its dimensions.
