This paper describes an attempt to shed some light on road safety in Asia Pacific region by characterizing and assessing its road accidents. The relevant national road accident data were extracted from centralized data sources of international agencies. Due to data incompleteness and missing values, 21 Asia Pacific countries, presenting more than half of the world’s population, were selected fo...

When a vehicle travels on a road, different parts of vehicle vibrate because of road roughness. This paper proposes a method to predict road roughness based on vertical acceleration using neural networks. To this end, first, the suspension system and road roughness are expressed mathematically. Then, the suspension system model will identified using neural networks. The results of this step sho...

Vehicle seat suspension is one of very important components to provide ride comfort, in particular, commercial vehicles, to reduce driver fatigue due to long hours driving. This paper presents a study on active control of seat suspension to reduce vertical vibration transmitted from uneven road profile to driver body. The control problem will be firstly studied by proposing an integrated seat s...

OBJECTIVE Road traffic injuries (RTIs) are the leading cause of disability-adjusted life years lost in Oman, Saudi Arabia and United Arab Emirates. Injury prevention strategies often overlook the interaction of individual and behavioural risk factors in assessing the severity of RTI outcomes. We conducted a systematic investigation of the underlying interactive effects of age and gender on the ...

give access to the through pavements only at limited intervals. Where pavements pass through highly developed areas, I think such service drives will be necessary to overcome constant interference of traffic turning in and out of the property with through traffic. These service drives would not, of course, be improved to nearly as high type as the through pavements. In most cases a surfacing of...

Translating R&D and inventive efforts into a market product is characterized by significant financial skills, and the ability to overcome technical and instititonal barriers. Research into and translation of new technologies such as biotechnology products to the market requires even greater resources. This paper aims to understand the key factors that foster or hinder the complex process of tra...
