Average Speed Bumps: Four Perspectives on Averaging Speeds [PDF]
CHANCE, 2005 highway, where each car travels at a constant speed. Assume that the distribution of the speeds is the same throughout the length of the highway. You adjust your speed so that during a given time unit you overtake the same number of cars as the number of cars that overtake you.

Speed bump–induced spinal column injury
The American Journal of Emergency Medicine, 2005Compression fracture of the vertebral body is common, especially in older adults. Injuries to the spinal column are one of the most frequent injuries by accidents and falls from heights. Vertebral fracture associated with minor trauma, however, is a rare occasion.Five cases were injured in the inner city buses after passing onto speed bumps are ...

This chapter will cover why China’s economic growth is slowing, and also why this is said to be an important juncture. Should we artificially stimulate economic growth or honestly, and stoically accept these new growth trends? In addition, what kind of policies should be adopted? These questions are not merely the focus of this chapter, but of interest

Do speed bumps really decrease traffic speed? An Italian experience
Accident Analysis & Prevention, 2001Italy introduced the extensive use of speed bumps only in 1990, in an attempt to limit the high number of fatalities involving pedestrians in urban streets caused by the high speed of vehicles. In many countries, such devices have been the subject of careful investigations (in order to assess their effectiveness and disadvantages for the traffic ...

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

The influence of speed bumps on perceived annoyance
The Journal of the Acoustical Society of America, 2008Recently, several attempts to use speed bumps as a noise reduction method have been made. Objective analyses of the effect of speed bumps on noise have been shown to result in a rather small reduction of noise. In the present paper the influence of speed bumps on perceived annoyance is investigated.
