“…After recording the inspection data into the sheets, surface distresses evaluation was calculated based on a numerical rating from 0 to 100, pavement condition index (PCI), as mentioned above. The calculation was performed using Micro PAVER software [3].…”

“…Layout parameters include spacing between speed hump, construction materials, marking, and signage. Many researchers have studied the potential positive and negative effects of calming devices, especially speed humps [1][2][3][4][5][6][7]. It is worth mentioning that very little work has been done to study the impact speed humps on the pavement condition [8].…”

In order to fight against over-speeding, the government and people in Egypt resorted to the installation of speed humps without adequate studies. On this basis, speed humps became widespread in most of the Egyptian roads in a semi-random way. It has been observed that the pavement condition of the roads has deteriorated in the vicinity of these humps. For impact assessment of speed humps on the pavement condition index (PCI), three roads link Kafr El-Sheikh city with three major towns in Kafr El-Sheikh governorate were selected to conduct PCI survey. The results indicated that the presence of speed humps contributes greatly to reduce the pavement condition index (PCI) values. It should be mentioned that the average reduction in PCI values ranged between 15% and 22% due to the presence of speed humps. Also, the most frequently observed distress on the pavement sections including humps considered for the selected roads was Raveling and Rutting. Accordingly, to avoid the pavement defects at the locations where the speed humps are installed, it is proposed to study the structural section of the road in the vicinity of the speed hump to resist the braking force and speed reduction effect.

Abstract. Speed bumps have been installed by the community on the streets of the Surakarta city residential area in various sizes to reduce the speed of vehicles passing through the street in order to protect citizens. This paper will analyse the correlation between speed bump dimensions and the observed speed of vehicles in the field. This research was conducted by taking samples from streets in residential areas in Surakarta by observing the decrease of effective speed at a distance of 8 meters before the speed bumps. The independent variables of this study are the width and height of speed bumps (cm) and the dependent variable is speed (km/h). Data were analysed using a regression equation. The results showed that the height of speed bumps is the most influential factor to decrease speed in the area before the speed bumps.

“…The forced vibration may result when disturbances occur determinedly such as passing over obstacles on a proving road. In this case even if there may be damping, the vibration may carry on & build up an undesirable level [19]. In India, the number of deaths on the road are increasing due to the extended road system as well as the nature of roads in India is also worrisome [20].…”

In today's automobile, each and every part of vehicle must consider the vibration management. Damping and isolation are the two aspects of vibration management which uses in conjunction to attain the required performance. The Logarithmic decrement method and Bandwidth method are the two major methods for measurement of damping in vibration system. Time domain method is used in Logarithmic decrement whereas the Half power bandwidth method is used in frequency domain analysis. In the present work, quarter car model is used to determine the frequency response analysis of Magnetorheological damper strut. The sprung mass is varying from 82 kg to 132 kg and excitation force is given by cam mechanism which is designed as per the bump size specified by Indian Road Congress (IRC) standard. The fabricated MR damper is tested at different sprung mass with input current from 0.1 A to 0.5 A. It is observed that the damping ratio is varying from 0.04 to 0.21. The results obtained in this paper will be helpful for the Indian auto industry to make more economical and reliable damper strut.
