| الوصف: | The geometry of invidivual humps and the spacing layout of humps are two key elements in the design of speed-control road humps. This study addresses the geometric design of individual humps. The paper examines the relationship between hump geometry and hump-crossing speeds of passenger cars in Singapore. Twenty-eight existing road humps were surveyed, including humps with different surface profiles, whose base widths varied from 1,736 mm to 4,120 mm and whose crown heights varied from 69 mm to 445 mm. No significant correlations were found between hump-crossing speed statistics and the height-to-width ratios of humps. However, by using the area-to-width ratio to characterize hump geometry, statistically significant regression relationships can be established with hump-crossing speed statistics. Using these relationships, a hump geometric design procedure based on the 85th percentile hump-crossing speed is proposed. |
