Optimization of Speed Control Hump Profiles

Journal of Transportation Engineering, 2009
In this study, the goal attainment method is implemented for the optimization of speed control hump profiles. Basic dimensions for a number of hump profile functions are optimized for single vehicles classified in five categories and for a specified distribution of these vehicles. Objective functions are selected as combinations of the longitudinal and

Impact of speed humps of bicyclists

Safety Science, 2016
Abstract Speed hump is one of the most popular and economical traffic calming measures used globally. It induces shocks and vibrations in the vehicles passing over it. Hump aims to force the driver to reduce the vehicle speed to an optimum speed at which the discomfort is minimum.

Dynamic considerations of speed control humps

Transportation Research Part B: Methodological, 1982
Abstract The objective of this study is to investigate the effects of hump parameters (cross section, dimensions, spacing, etc.) on the dynamic behaviour of the vehicle and the driver. Vehicle safety and driver comfort are most important in evaluating the effectiveness of speed control humps.

Multiobjective shape optimization of speed humps

Structural and Multidisciplinary Optimization, 2008
This paper presents a new approach to the shape optimization of road speed humps. The proposed approach is based on multiobjective genetic optimization of the hump profile while taking into account the separation phenomenon, which occurs when the front tires of the vehicle momentarily lose contact with the road surface.

Effects of speed humps on vehicle speed and pedestrian crashes in South Korea

Journal of Safety Research, 2020
Speeding is a crucial risk factor for pedestrian safety because it shortens reaction time while increasing the impact force in collisions. Various types of traffic calming measures to prevent speeding have been devised. A speed hump-a raised bump installed in the pavement-has been widely used for this purpose.To evaluate the effectiveness of speed ...

Profile Optimization of Table Top Speed Hump for Speed Control

Volume 8: 11th International Power Transmission and Gearing Conference; 13th International Conference on Advanced Vehicle and Tire Technologies, 2011
Speed bumps are the most commonly used measure to control speeding in urban areas world wide. Specifications on profiles and dimensions are largely based on road tests. Studies into speed bumps, directed at evaluating their effectiveness in reducing accidents and their environmental impact, have brought some negative aspects concerning speed bumps to ...

Effects of Speed Bumps and Humps on Motorcycle Speed Profiles

Advanced Materials Research, 2014
In developed countries, the use of speed humps and bumps have evolved from extensive research and testing which been properly designed and standardized. On the contrary in developing countries, no systematic and scientific studies have been carried out on that environment, especially the study on the effects that the motorcyclists response to the humps
