LEX RUSSICA CRIMINAL LAW A.I. Chuchaev* TRANSPORT CRIME MECHANISM (concept and general characteristics) Abstract. <...> The article considers the mechanism of transport crime basing on the polyergatic essence of rail, water and air transport and on monoergatic essence, i.e. vehicles. <...> It gives the classification of ergatic systems, their relationship, analyzes the disputable issues of crime mechanism in general and negligent crimes in particular, formulates the concept of transport crime mechanism, stands its objective (technical system, informational system and situation) and subjective (subject to drive the transport) elements, shows the distinction between criminal and criminological concept of crime mechanism, the ways of harming public relations characterizing safety of transport operation. <...> Keywords: jurisprudence, transport, ergatic system, mono-and polysystem, classification of ergatic systems, transport crime, criminological mechanism, penal mechanism, elements of the mechanism, operator, technical system, informational system, situation. <...> W hen determining the mechanism of transport crime it is necessary to base on transport characteristics. <...> Railway, air and water transportation refer to typical polyergatic systems, i.e. «physical, object- orientated, closed systems including a man as the main, decisive link»1 ; and road transport, as a rule, to monoergatic systems. <...> Ergatic systems available on the transport, differ in the number of operators, degree of continuity of human involvement in the management of the process, kind of communication of the operator with the object driven. <...> According to the degree of the continuity of human involvement in the management we can differ systems, where the operator works in the immediate or deferred maintenance. <...> In the first case 1 Platonov G. Ergonomics at the railway transport. <...> P. 14. he commits control actions on the object taking into consideration the received information, assessment, etc. <...> Violation of the continuity degree of participation of the operator in the control actions (when managing or general subject «falls« from the system or makes mistakes) can cause transport accidence. <...> The task in this case is to find out causes of erroneous actions, which, in its turn, allows to formulate recommendations aimed at eliminating the defects of transport worker behavior, strengthening its «operational« reliability. <...> However, it should be borne in mind that the transition from one mode to another (such as from automatic control to the manual one <...>
