The operating methodical device in bodies of system of the Ministry of Justice of the Russian Federation has no methods (has no accurate position on application of the separate techniques successfully used in foreign practice already more of 25 years) allowing to solve a private engineering problem, such as an establishment of expenses of energy on HARDWARE deformation, definition of actual trajectories of moving’s of the HARDWARE, definition of speeds of movement of objects by the time of contact and their spatial position during the set moment of time before collision more precisely. The given lacks of operating system of many cases lead to impossibility of definition of parameters of separate phases of the mechanism of road accident (rapprochement – contact – scattering) or a blank impossibility of reconstruction of the mechanism of road accident. That as consequence furnishes to impossibility of the proof or a causal relationship refutation in actions of drivers and the come consequences. At the moment, experts under the analysis of road and transport incidents of Institute of safety of traffic SPBGASU are engaged in research activity, collect the data of dynamic parameters of motorcycles. Brake mechanisms of motorcycles are thus investigated, falling (drawing) of a motorcycle together with a dummy for revealing of dependences of parameters of braking in particularly considered situation, for deducing of the dependences necessary for calculation of speed of a motorcycle is simulated. It will allow универсализировать the mechanism of calculation of speed of movement of a motorcycle by the time of collision proceeding from various variations as crash interactions and rapprochement and scattering stages. Thereby, conducted researches will allow to raise reliability of definition of the reasons of road accident with participation of motorcycles and accuracy of reconstruction of the mechanism of road accident in expert researches.
