Nearly every town faces the traffic problem caused by the continuous increase of the traffic volume. Traffic collapses, congestions, accidents and a further negative impact on the environment are gradually becoming a common part of our lives. Junctions are the most critical points of the road network, which usually determine the capacity of the roads. Therefore, proper traffic organization at junctions is a necessity. This paper analyses the actuated control in comparison to the fixed control at a signal-controlled junction. It also includes a case study of one problematic junction in this paper. With the help of microscopic simulation in Aimsun, 2 solutions for this problematic junction were assessed, one of which is fixed control and other is actuated control. Actuated traffic control gives better results than fixed control.

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.

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 externs 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 mesurées.

W artykule przedstawiono wpływ trzech koncepcji zmian organizacji ruchu w obrębie pierwszej obwodnicy Krakowa na ruch tramwajów. Analizie poddane zostały koncepcje: ruchu jednokierunkowego, strefy dzielonej oraz połączenie koncepcji ruchu jednokierunkowego i strefy dzielonej. Każda koncepcja została w artykule szczegółowo opisana. Na podstawie zebranych danych przygotowane zostały modele symulacyjne, dzięki którym możliwa była ocena każdej z koncepcji. W artykule przedstawiono sposób kalibracji oraz szczegółowo opisano każdy z modeli. Wyniki zbierane były zarówno dla transportu tramwajowego, jak i autobusowego, dla godzin porannych i popołudniowych. Zostały one zaprezentowane w formie wykresów i tabel umożliwiających łatwe ich porównanie.

The article presents the impact of the three changes concepts in the organization of traffic within the first ring road in Cracow on the trams traffic. Concepts of: one-way traffic zones, shared space zone and merger concept of one-way traffic with the shared space have been analysed. Each concept has been described in detail in the article. Based on the collected data simulation models have been prepared which allow assessment of each concept. Method of calibration has been described in the article as well as detailed description of all models has been presented. Results have been collected for both: trams and buses as well as for the morning and afternoon hours. They have been presented in the form of graphs and tables to enable easier comparison.
