Abstract
Modern times are characterized by fast economic and social development. However, not all spheres of life have developed in a sustainable manner, for example some elements of anthropotechnical systems are still far from being sustainable. This results in low safety level of these systems involving high risk of injury or death caused by road accidents. Transport systems of the type Human-Machine-Environment <H-M-E>, where undesired events are caused by human behavior, belong to such systems. The author of this study has addressed the issues connected with the impact of man-made objects on their operation safety. The objects in question are selected transport systems and the study subject is assessment of the equipment operator’s behavior. The main goal of this study is to provide assessment and analysis of the impact of transport means ergonomics on the quality of transport services they provide. The research object are delivery trucks with the maximum vehicle weight up to 3.5t. The first part of the study contains identification of the factors and threats which affect functioning of transport systems. Further, ergonomics criterion is defined and the factors affecting ergonomics of selected transport means are provided. A questionnaire survey was performed with participation of professional drivers who were asked to identify the factors which have an adverse effect on the safety of the transport process as well as factors that increase the drivers’ comfort of work. Basing on this, an analysis of the results was performed and negative aspects involved in driving ergonomics were identified.
Highlights
The problems connected with the safety of transport systems is an interdisciplinary issue and applies to transport psychology, theory of systems, ergonomics, transport, maintenance and others [1,2].Socio-technical systems H–T–E, including transport ones, are characterized by similar features regardless of the industry they are used in
Transport systems are specific types of socio-technical systems where more than 90% of the undesirable events are caused by fault of the human
The decisions of a vehicle operator, that is a driver, which are frequently affected by the ergonomic factors, have a significant impact on the vehicle
Summary
The problems connected with the safety of transport systems is an interdisciplinary issue and applies to transport psychology, theory of systems, ergonomics, transport, maintenance and others [1,2]. Socio-technical systems H–T–E , including transport ones, are characterized by similar features regardless of the industry they are used in The level of their safety is affected by the operator’s behavior (human factor), the technical object (transport means) and the impact of the environment. Study [7] provides an analysis of the human factor concept, for the needs of this study, a definition was accepted which assumes that a human factor is a general term commonly used as a name of a specialized discipline which deals with the relations between a man an a machine It focuses on the problems of perception, psycho-physics, decision making and other aspects involved in the information processing. A respective directive includes major requirements regarding safety and health protection in relation to all machines [13]
