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 current COVID-19 pandemic situation has a very significant impact on urban mobility, as evidenced by fundamental changes in passengers’ behavior. In many cases, passengers have switched to other modes of transport to minimize the risk of infection (particularly cycling and walking). This paper aims to point out the analysis results of the impacts of a bike-sharing system in the city of Košice before and during the COVID-19 pandemic. Additionally, this paper describes an analysis of the current state of bike-sharing in the Slovak Republic. We have stated a timeline of significant dates related to the COVID-19 pandemic. COVID-19 had a significant impact on people’s mobility and bike-sharing, as evidenced by the graphs and results in this paper.
Summary. Every increase in traffic volume on road network in towns can lead to overcrowding of road network. This results in undesirable external costs such as traffic congestions, which cause high loses in time during transportation, increased fuel consumption and thus higher production of greenhouse gases and noise. This all ultimately reduces the attractiveness of the area. The increase of traffic volume and therefrom derived traffic problems are needed to be solved during traffic-capacity assessment of every larger investment. The software can help to assess increased traffic in solved area and thus help authorities to make a right decision during approving of the investment plan. This article is focused on comparison of two software -Aimsun and OmniTrans, and calculations according to Webster and technical regulations for assessing junction capacity in the Slovak Republic. The packages outputs are also compared to the measured data at the assessed junction in this article. The analysis showed that outputs of various tools differ, generally all packages showed higher delays compared to measured data at the main road and lower delays compared to measured data at the side roads. CALCUL DE LA CAPACITÉ DES CARREFOURS À FEUX AU COUR DE L'ÉVALUATION DES CAPACITÉS DE TRAFIC -LA COMPARAISON DES RÉSULTATS DE AIMSUN, OMNITRANS, WEBSTER ET TP 10/2010Résumé. Chaque augmentation du volume de trafic sur le réseau routier dans les villes peut conduire à la surcharge du réseau routier. Il en résulte des coûts externes indésirables tels que des embouteillages, qui provoquent de grands retards pendant le transport, augmentation de la consommation de carburant et donc la production plus élevée de l'effet de serre et du bruit. Finalement, cela réduit l'attractivité de la région. Cette augmentation du volume de trafic et des problèmes de circulation en dérivés devraient être résolues par l'évaluation des capacités de trafic des impacts de chaque investissement plus important. En faisant cette évaluation, il est possible d'utiliser des logiciels qui aident à évaluer des effets de l'augmentation du trafic dans la zone observée et donc ils aident les autorités compétentes à prendre les bonnes décisions. Cet article se concentre sur la comparaison des deux logiciels -Aimsun et Omnitrans, et la comparaison des calculs selon Webster et selon des règlements techniques pour l'évaluation des capacités de communications terrestres de la République slovaque. Les sorties des instruments individuels sont en outre comparées avec les données mesurées 122 Ľ. Černický, A. Kalašová, J. Kapusta sur le carrefour observé. L'analyse a montré que les sorties des différents instruments diffèrent, sur la route principale, le retards mesurés sont supérieurs aux sorties des instruments individuels, tandis que sur la route secondaire, des retards mesurés sont inférieurs à ceux des sorties de ces instruments.
