Transport safety assessment plays a huge role in theory and practice of implementation of transport management systems. It should be noted that ensuring the transport safety is inextricably linked to identification of potentially dangerous transport situations and their risk assessment. To better manage transport risks, we propose to apply a new integrated approach which allows to take into account the source of the threat, the degree of objects’ protection, kinds of threats, extent of damage in the event of dangerous situations, magnitude of the dangerous situation. This approach is anchored to systematic analysis of causes and conditions of formation of dangerous situations. Also, it provides timely forecasting of their development and consequences.
Therefore, it is necessary to develop a new approach to transport risk assessment which will be able to effectively evaluate occurrence of dangerous transport situations. Incorporation of this approach in transport management systems will reduce the costs for their elimination, improve the quality and coherence of actions should dangerous transport situation occur.
In this paper we present components of transport safety and provide a list of typical objects of transport infrastructure. Transport safety model and algorithm for identification of potentially dangerous transport situation is proposed. Also, we consider a new integrated approach based on transport risk assessment method.
It is worth highlighting that the proposed method of transport risk assessment allows to take into consideration the uncertainty linked to the occurrence of dangerous transport situations and their conditions. The specified method can be widely used in modern geographic information systems for analysis of transport emergencies.
