Studies in the Area of Transportation Engineering Reported from Imam Khomeini International University (Optimization of Speed Hump Profiles Based on Vehicle Dynamic Performance Modeling)

By a News Reporter-Staff News Editor at Journal of Engineering -- Fresh data on Transportation Engineering are presented in a new report. According to news reporting originating from Qazvin, Iran, by VerticalNews correspondents, research stated, "Speed humps are in widespread use around the world. Despite their effective performance in increasing safety, they cause considerable damage to vehicles and discomfort to drivers and passengers."

Our news editors obtained a quote from the research from Imam Khomeini International University, "This paper investigates the dynamic response of vehicles on different types of speed humps using a multibody simulation software package that is popular in the automotive industry. Following this evaluation, two new profiles are recommended to optimize the dynamic performance of speed humps. A series of formulas are also presented to estimate the dynamic performance of passenger cars on flat-topped and parabolic humps based on vehicle speed, hump dimensions, and driving behavior while traversing the hump. The results show that, for flat-topped humps, the ramp length ( or entrance slope) has the greatest effect on vehicle performance."

According to the news editors, the research concluded: "It is found that the dynamic performance of the recommended profiles is much better than that of conventional humps."
