Abstract
The surveyof traffic intensity is used to obtain information on the number of vehicles on roads during the day. Subsequently, it is possible to derive from this the daily, weekly, and other road traffic intensity information. This survey represents the basis for the calculation of the annual average daily traffic volume and the basic characteristics of traffic flow. The COVID-19 pandemic has caused extensive economic and social damage around the world. These damages have also affected traffic. Changes in traffic behavior have mainly affected the reduction in traffic intensity on road networks. Thanks to the reduction in the demand for transport, there has also been a significant reduction in traffic delays, fuel consumption and emissions. An examination of changes in traffic intensity took place at a selected intersection in 2019, 2020 and 2021. This paper describes the effects of reducing the traffic intensity, fuel consumption and emissions obtained by microsimulation. The results obtained confirmed the reduction in traffic, which also contributed to a significant reduction in vehicle delays.

Summary
Introduction and Literature Review a SelectedIntersection in Slovakia.Road transport currently encompasses a large number of vehicles. In 2020, more than 11.6 million vehicles were registered in the European Union [1]. This figure has become a serious problem, leading to road congestion, greenhouse gas emissions and fuel consumption. Traffic flow theory is a tool that helps traffic engineers understand and express traffic flow characteristics. Millions of vehicles are on the road all the time around the world. These vehicles affect traffic flow and interact with each other. A traffic engineer must have a good understanding of traffic flow theory. Examining traffic flow is a very interesting and current topic [2] and it is a nonlinear dynamic phenomenon
