Examining the Speed Reduction Characteristics of Urban Residential Streets in the Upstream Side of Speed Humps
The speed humps can reduce vehicle speed at hump location effectively. However, practitioners require to understand comprehensively the speed reduction mechanism of a single hump in case of a long road section. Therefore, the present study is designed to investigate the external geometric and non-geometric factors, associated with speed reduction in the upstream of humps. A total of 500-speed data were collected from 7 different residential streets in Japan. Using multiple linear regression analysis, various road geometric features were found as significant predictors for speed reduction i.e., street marking, road width, two-way traffic, presence of the sidewalk, etc. A non-geometric factor named “street with many pedestrians” also found significant. The findings of this study can help practitioners to find out the optimum placement of a single hump along the road section. Furthermore, the speed at the upstream of hump can also be predicted before installation, by using the developed models.
