The article discusses the issue of assessing the impact of automotive transport infrastructure on the economic development and economic security of the territory. Due to the lack of a specific method for identifying the contribution of road infrastructure to the economic security of a territory, the authors propose their own methodology based on the consideration of dynamic indicators of the formation, functioning and development of road transport infrastructure, which are selected according to the principle of public accessibility from government statistics bodies. An example of testing the methodology is based on data from the Sverdlovsk region over the past few years.
