Although public health efforts have made some progress in reducing risk of adolescent motor vehicle crashes over the last three decades, new technologies and evolving behavior patterns have focused attention on the risk of distracted driving. For many of the same reasons that alcohol-impaired driving represents a distinct risk for adolescents, distracted driving has an elevated impact on this a...

in this paper, vehicle’s fuel consumption and exhaust emissions are investigated in different driving conditions based on driving segments clustering. driving data collection is performed using global positioning systems in real traffic conditions. the driving data is clustered into five groups using k-means clustering technique. vehicle’s fuel consumption and exhaust emissions (i.e. hc, nox a...

background and objectives: day-shift taxi drivers have a long duration of direct sun exposure. however, the efficiency of this occupational exposure in vitamin d synthesis has not been addressed yet. the aim of this study was to assess the vitamin d status of taxi drivers in tehran, and examine vitamin d status association with some anthropometric and circulating biomarkers. materials and metho...

This paper presents a design procedure for an adaptive power management control strategy based on a driving cycle recognition algorithm. The design goal of the control strategy is to minimize fuel consumption and engine-out NOx, HC and CO emissions on a set of diversified driving schedules. Seven facility-specific drive cycles are considered to represent different driving scenarios. For each fa...

driving is a complex psychomotor task involving distinct cognitive, perceptual and decision making skills. it needs to more concentration and alertness to driving safe. several studies have shown the potential effects of alcohol in crash production by epidemiological and laboratory analysis. alcohol is obviously the most common single cause of traffic accidents in america. a review of the relat...
