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.

Distance between speed humps and pedestrian crossings: Does it matter?

Accident Analysis and Prevention, 2011
Speed humps are a common physical measure installed at pedestrian crossings to reduce vehicle speeds therefore improve the safety and mobility of pedestrians at the crossing.

Speed Hump Spine Fractures

Journal of Spinal Disorders & Techniques, 2011
Retrospective case series.To describe an injury mechanism and a series of patients with spine fractures after passing over speed humps in a motor vehicle.The use of speed humps as an effective measure to reduce the rate of traffic accidents is still a matter of discussion.

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

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

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.

Evaluation of speed humps and tables in Qatar

Journal of Local and Global Health Science, 2015
Controlling the speed of vehicles on various roads and streets is crucial in order to maintain the safety of people and to prevent any possibility of injury or death. One technique that is widely used in Qatar to force road users to reduce their vehicles’ speed is the installation of speed humps and tables.

An efficient urban localization method based on speed humps

Sustainable Computing: Informatics and Systems, 2019
Abstract Outdoor localization is of great importance for driving navigation, attracting many research efforts in past decades. Prevailing GPS achieves meter-level localization accuracy under general outdoor conditions. Yet, GPS service performs poorly in urban canyons where skyscrapers block GPS signals and drain mobile phone battery quickly within ...

The use of road humps for moderating speeds on Urban streets

Accident Analysis & Prevention, 1992
Road humps are devices placed in the path of traveling vehicles. They are used in many communities to keep a uniform and low speed on a residential street or to reduce speeds at specific locations, such as intersections or pedestrian crosswalks.

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 ...
