Sleep-related complaints have become a highlight for physicians as well as public health administrators. Studies of sleep patterns and sleep-related complaints of shift workers have been useful in minimizing reduction in the quality of life due to the warping of the sleep-wake cycle. The objective of the present study was to assess patterns of sleep, sleep-related complaints as well as physical...

Workers in the transportation industry are at greater risk of an incorrect diet and sedentary behavior. The aim of our study was to characterize a population of professional bus drivers with regard to clinical and demographic variables, lipid profile, and the presence of cardiovascular risk factors. Data from 659 interstate bus drivers collected retrospectively, including anthropometric charact...

Long driving hours have a potential of causing fatigue, which is known as a contributing factor for collisions. This paper examines the influence of bus operator driving hours on the occurrence of preventable collisions by employing data from incident reports and operator schedules to evaluate the correlation between driving hours and operator involvement in collisions. Several methods of analy...

BACKGROUND One of the most popular means of public transport within South Africa is mini-bus taxis. OBJECTIVES As South Africa is made up of diverse cultures, religions and beliefs, the aim of this study was to explore Johannesburg based taxi drivers' experiences of beliefs about, and attitudes towards passengers who have a communication disability. METHOD Semi-structured interviews were co...

The Americans with Disabilities Act (ADA) specifies guidelines covering the securement system and environment for wheeled mobility device (WhMD) passengers on the public bus system in the United States, referred to as the wheelchair tiedown and occupant restraint system (WTORS). The misuse or disuse of the WTORS system can be a source of injury for WhMD passengers riding the buses. The purpose ...

in many countries road crashes are the main cause of fatal accidents related to job. the aim of our study was to characterize a population of iranian professional drivers with regard to history of drivers’ road crash incidents and some occupational factors. using swedish version of the nordic questionnaire information about musculoskeletal pain prevalence in last 12 months, demographic features...

This paper describes the design of the Bus Timetabling System (BTS) we have developed for one of the largest privately held bus companies in the world. This Bus Company operates close to 3,500 buses and employs over 7,500 bus drivers. The BTS generates a timetable for each bus route using “distributed constraint-based search” (DCBS). The DCBS algorithm combines techniques of constraint programm...

|A exible architecture for a microinstrumentation system in silicon was developped, and intended for use in a wide range of applications. The MCM device should be considered a genuine (micro)instrument, which supplies highlevel data over an external instrumentation bus. Internally, the system should support all vital functions, such as power management, self-calibration and in-system data trans...
