Urban Road Speed Humps Setting Technology
ICTE 2015, 2015Set the speed control humps scientifically, both from the reminder and to decelerate purpose, effective protection of urban road traffic safety. The paper describes the function of speed humps’ reducing accidents. Basing on the comprehensive analysis of domestic and foreign studies of speed humps, it further analyzes the influencing factors of ...

Dynamic considerations of speed control humps
Transportation Research Part B: Methodological, 1982Abstract 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.

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, 2011Speed 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, 2014In 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

Humping mechanisms present in high speed welding
Science and Technology of Welding and Joining, 2006As welding speeds continually increase owing to automation and newer processes, a common defect that occurs is humping. Humping is the periodic occurrence of beadlike protuberances. The objective of the present investigation is to review current and previous researches that were made on humping, including both experimental and theoretical studies.

Optimal road hump for comfortable speed reduction
SPIE Proceedings, 2008We propose a practical tool for exploring the dynamic relation between road profiles and vehicle motion in the time domain. It is symmetric in the sense that the direct (vehicle response to a given road profile) and the inverse (ideal road profile for a given response) problems are both solved by means of digital filtering. The dynamics of each vehicle

The Best Speed Limit Range for Road Hump
Applied Mechanics and Materials, 2014Through simulating the process of vehicle running over humps in CarSim, calculating and analyzing the body vertical acceleration, the wheel load and wheel ground adhesion index for the car with different speeds that runs over road humps having different height and width, so as to obtain the effect of height and width of the hump on the deceleration ...

Humping reduction methods for high speed laser welding
ICALEO 2009: 28th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2009Conventional pulsed laser welding is typically done at speeds on the order of millimeters per second, which is too slow to be economically feasible for future energy applications such as laser welding bipolar plates for fuel cells. A typical fuel cell stack may have hundreds of feet of welding which must be executed with high precision and no defects ...

Evaluation of speed humps and tables in Qatar
Journal of Local and Global Health Science, 2015Controlling 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.
