The transport strategy of the Russian Federation, taking into account the specific features of the country's transport system, requires the use of transport modeling when solving problems of carbon neutrality. The transport model solves multifaceted problems, including the forecast and assessment of greenhouse gas emissions. The main principles of developing transport models are considered. A comparison is made of the NIIAT and EEA/COPERT methods most often used in calculating greenhouse gas emissions using transport models. The main requirements for the results of calculations using a mathematical model of transport flows are formulated.
