Abstract: The subject of the study is the patterns of detection, fixation, preliminary research, the use of criminally significant information and means of processing it in order to identify, disclose, investigate and prevent crimes, as well as the creation of technical means, techniques, recommendations, automated information systems (AIS) optimizing the investigation and disclosure of crimes based on the knowledge of these patterns. The author examines in detail the issue of creating automated crime investigation techniques – a type of information decision support systems. Special attention is paid to the components (databases) of AIS and their content. The author comes to the conclusion that one of its components is the database "Targeting". The functioning of this component and the automated system as a whole should be based on the provisions and laws of forensic science. The methodological basis of the research is represented by the universal dialectical method of scientific cognition, general scientific methods of empirical and theoretical cognition, private scientific methods (formal logical, modeling), as well as special scientific methods (structural criminalistic, etc.). The main conclusions of the study are the definition of the main (basic) structural component of the automated crime investigation methodology - "Targeting". This database should include two blocks: 1) a block of circumstances to be established and proved during the investigation of crimes with the possibility of data entry by the investigator, which will allow specifying these circumstances, taking into account the investigation he is conducting; 2) a block providing the definition of goals in the investigation of non-obvious crimes. At the same time, the system of goals formed according to the crime under investigation is fixed in the AIS as a separate file, with the possibility for the investigator to access its contents and adjust the system of goals taking into account the progress of the investigation. This will make it possible to make a breakthrough in the creation of automated investigation techniques.

Abstract: The object of the study is crimes against road safety and the operation of transport, as well as the activities of the subject of the investigation aimed at fully establishing all the circumstances of a traffic crime. The subject of the study is the regularities of the situation and mechanism of this group of crimes and the regularities of the investigator's activities to establish them during the investigation. When forming conclusions, the author was guided by the analysis of the norms of the Criminal Code of the Russian Federation, the Criminal Procedure Code of the Russian Federation, other laws regulating the investigation of this group of crimes, the theoretical foundations of criminalistics, materials of investigative and judicial practice, in addition, he used the results of a survey of 137 full-time employees of investigative bodies in the Krasnodar Territory who have practical experience in investigating crimes against road safety and operation transport. The author examines in detail the specifics of the investigator's establishment of the situation and mechanism of a traffic crime, with special attention paid to the issues of detecting and obtaining information about the incident recorded by technical means of objective control. The authors note that when investigating a crime against road safety and the operation of transport, a competent study by the investigator of the situation and the mechanism of the crime is a key component of his cognitive and certifying activities to establish the truth in a criminal case. The conducted research made it possible to identify certain shortcomings allowed during the detection, removal and fixation of traces, during the inspection of the road network, at the scene of the incident, the author also notes the low level of use of information technologies by investigators when establishing the mechanism of a traffic crime. The authors suggest ways to eliminate these shortcomings: in order to obtain objective data about the various circumstances of the accident, it is necessary to use more actively the information recorded by the technical means of objective control, to implement in investigative activities a program for computer modeling of the mechanism of an accident.
