This paper looks into the possibility of using the regular traffic patterns provided by public buses to improve the performance of Mobile Ad-hoc Networks (MANET) for Inter-vehicular communications systems (IVCS). MANET is an adhoc network with mobile nodes that are random and unpredictable. IVCS provide drivers and passengers with a range of services, and implementation of IVCS is possible usin...
Public transportation has been one of the most important research fields in the two last decades. The purpose of this paper is to create a schedule for public transport fleets such as buses and metro trains with the goal of minimizing the total transfer waiting time. We extend previous research works in the field of transit schedule with considering headways of each route as decision variables....
OBJECTIVES Few low income countries have emergency medical services to provide prehospital medical care and transport to road traffic crash casualties. In Ghana most roadway casualties receive care and transport to the hospital from taxi, bus, or truck drivers. This study reports the methods used to devise a model for prehospital trauma training for commercial drivers in Ghana. METHODS Over 3...
BACKGROUND The way the municipal transport drivers perform their job contributes to varied burdens linked with the body posture at work, stress, shift work, vibration, noise and exposure to chemical agents. The aim of the study was to assess the condition of the nervous system (NS) in municipal transport drivers. MATERIAL AND METHODS The study covered 42 men, aged 43.4 years (standard deviati...
Background and Objective: Most accidents can be directly attributed to human factors. The aim of this study is to determine the validity and reliability of drivers aberrant behavior questionnaire in urban Bus Company. Materials and Methods: This descriptive study was performed on 168 subjects (in order to exploratory factor analysis) and 161 subjects (for the sake of confirmatory f...
A signi cant aspect of the transport companies is to decrease their operational costs. This can be done by optimizing their public transport services. Usually the operational cost of the transportation consists of the cost of the used vehicles and their drivers. It is a very complex task to solve such optimization problems and usually the optimized planning process is divided into more phases. ...
Background and purpose: High concentrations of respirable particles may cause high incidence of respiratory diseases and mortality in public populations and in particular in public transportation workers. Epidemiological exposure studies showed that respirable particles that emitted from traffic sources have more potential effects on more incidence of hospitalization or mortality caused by ca...
BACKGROUND What we eat simultaneously impacts our exposure to pathogens, allergens, and contaminants, our nutritional status and body composition, our risks for and the progression of chronic diseases, and other outcomes. Furthermore, what we eat is influenced by a complex web of drivers, including culture, politics, economics, and our built and natural environments. To date, public health init...
