OBJECTIVE To analyze the putative effect of type of shift and its interaction with leisure-time physical activity on cardiovascular risk factors in truck drivers. METHODS A cross-sectional study was undertaken on 57 male truck drivers working at a transportation company, of whom 31 worked irregular shifts and 26 worked on the day-shift. Participants recorded their physical activity using the ...

This paper suggests that a universal psychophysical law influences the perception of risks and physical quantities in traffic. This law states that there will be a tendency to overestimate low probabilities or small quantities, while high probabilities or large quantities may be underestimated. Studies of the perception of risk and physical quantities in traffic have found a highly consistent p...

The avoidance behavior of drivers over the age of 65 was compared with drivers under the age of 60 years in an emergent traffic situation where an obstacle vehicle drives into a blind intersection in a driving simulator. The drivers generally tended to do their best driving as the required reaction time in the situation decreased. However, the avoidance performances of the older drivers were mo...

BACKGROUND Urban taxi drivers differ from other professional drivers in their exposures to physical and psychosocial hazards in the work environment. Epidemiological data on low back pain (LBP) of this occupational group are very scarce. AIMS To examine LBP in taxi drivers and its association with prolonged driving and other occupational factors. METHODS We analyzed the cross-sectional data...

Automobile crashes are the leading cause of death for those aged 3 to 33, with 43,005 (118 per day) Americans killed in 2002 alone. Seat belt use reduces the risk of serious injury in an accident, and refraining from using a cell phone while driving reduces the risk of an accident. Cell phone use while driving increases accident rates, and leads to 2,600 U.S. fatalities each year. An active pro...

This paper investigates the age and sex distribution of at-fault drivers with respect to fatal crashes on the interstate and state highways in Florida. The study finds that the younger and older drivers of both sexes are more likely to cause fatal crashes compared to the „average‟ middle-aged drivers. The female oldest (>=75 years) drivers are at highest level of vulnerability of causing fatal ...

results mean age was 41.6 ± 9.2 for the military truck drivers and 43.4 ± 10.9 for commercial truck drivers (p > 0.05). no significant difference between military and commercial drivers was found in terms of driving experience, number of mvcs, binocular va, frequency of color vision defects and cs scores. in contrast, the last ocular examination was significantly earlier in military drivers tha...
