“…The traffic flow is understood as the unity of temporal and spatial characteristics but also of the transport and motoric characteristics of vehicles on the road. The movement of vehicles in traffic flow is affected by other vehicles in the traffic and is therefore monitored as a whole and not as the movement of an individual vehicle [33][34][35].…”

Transport is an inseparable part of the life of all citizens. At the beginning of the year, the COVID-19 pandemic hit the world. Individual states have taken strict measures to prevent its spread among the population. Due to this fact, the government of the Slovak Republic has issued restrictions on the closure of public spaces (schools, shopping centres, restaurants, bars, etc.). These restrictions have had an impact not only on the economic activity of the population but also on their mobility in the form of reduced traffic. This is due to the drastically reduced mobility associated with the coronavirus, such as commuting trips and extremely limited leisure opportunities. Reduced mobility of the population (reduction of the number of vehicles in the traffic flow) can bring positive effects not only on overloaded road network (increased vehicle speed, lower flow) but also on the environment (reduction of noise, emissions, etc.). This article aims at finding out what effect the measures taken had on the quality of traffic flow. The quality of movement was examined in the form of the flow and speed of vehicles on one of the busiest first-class road sections. Descriptive statistics were used to examine the state of the restrictions. The results show that after the introduction of measures against the spread of coronavirus, the intensity and speed of vehicles in the measured section decreased.

“…The quantity of the traffic flow is its flow and the quality expresses the speed and fluency in the given conditions. The research and description of the relationships between these three variables is the basis of the traffic flow theory [33,35,36].…”

“…Evidence that the content of CO 2 in the atmosphere is continually increasing is also provided in Figure 3. It shows the increase in CO 2 in the air in Hawaii, where the greenhouse gas content is not distorted by intensive industrial activity [13,19,22]. All three pictures correspond to each other and show the increase in free CO 2 in the air as time goes on.…”

Climate change and the associated global warming affect all of us. These changes cause the melting of the glaciers and consequently the increase in sea and ocean levels. This phenomenon threatens the existence of some of the island states. The warming casing all this was brought on by the economic activity of humans, with the greatest responsibility being attributed to the ever-increasing production of greenhouse gases. Transport generates large portion of these gases. When means of transport are in motion, they are affected by certain driving resistances which try to keep vehicle from moving. In order to overcome them, it is necessary to produce certain useful work equivalent to the measurement of driving resistances. An internal combustion motor is the most frequent source of such energy. It generates energy by oxygenating hydrocarbon fuels, and in addition to the useful work, it produces also unfavourable emission. The amount of such emissions equals to the amount of burnt fuel. Thus, levels of emissions can drop by reducing fuel consumption. The most commonly mentioned gas is the CO2. Reduction of CO2 production is essential to affect the high level of CO2. The article focuses on the possibilities of reducing CO2 from road transport. The possibilities of reducing CO2 from road transport are quantified in the form of mathematical model calculations.

“…In Slovakia, there is the National Traffic Information System. This is a system environment that fulfils the following tasks related to the data on the actual traffic situation on the road network of Slovakia and other traffic information-acquisition, processing, provision, publication and distribution [46,47]. Specifically, we calculated and compared one average workday from 6:00 to 18:00.…”

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.
