Modelling traffic flows is a challenging task due to the high dynamism and stochasticity of the processes. Existing methods often do not take into account the mutual influence of events, which reduces the accuracy of forecasting. The aim of the paper is to propose a method for modelling traffic flows based on the composition of Petri nets with constraints on the time period of triggering transitions, which allows to analyze complex scenarios, including traffic accidents. The paper presents an approach that uses a composition of Petri nets with constraints on crossing time to describe the interaction between traffic flows and infrastructure. The method includes formalization of traffic rules, consideration of random events and analysis of system states. The application of the proposed approach is demonstrated on the example of road traffic accident modelling. The developed model allows analyzing traffic flows with high detail, including emergency situations. Experimental verification has shown the adequacy of the proposed model and the possibility of obtaining the characteristics of the traffic flow, for further assessment of the impact of accidents on the road situation and prediction of consequences. The proposed method can be used to optimize road infrastructure, develop traffic management systems and simulate emergency situations. The approach has the potential for integration into intelligent transport systems.
