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.

Life on the road with all its aftermath and consequences works as a big triangle: driver-road-car. The main cause of road accidents is driver who can´t cope with increase of traffic density and with more and more powerful cars. Increasing number of new vehicles on our roads shows certain economic power of Slovakia and improving standard of living. The annual growth of more than seventy thousand new cars has as a result overcrowded Slovakian road network. Because of this, there is a special attention given to road traffic safety and its various factor at the present not only in our country, but also in the European Union. By joining the European Union we are committed to achieve standards in all areas that are comparable with European developed countries. In our paper we would analyze accident rate of traffic in recent years in Slovakia and design telematic measures to reduce it.

With increasing traffic volume and traffic capacity the accompanying negative characters are still more proved and the problems have been associated with the establishment and functioning of the transport system. The mentioned problems are mainly: –– negative impact on the environment, –– increasing number of traffic accidents, threats to human health and life, –– traffic congestion, breakdowns and other negative impacts. Road safety is a serious problem of road transport development. Although, the accident rate in Slovakia generally decreases in recent years, its consequences are enormous and it is difficult to quantify it. Traffic accidents cannot be completely eliminated, but it is possible to reduce the number and severity of accidents with the cooperation of various research institutes, international organizations and experts from different fields of science with ministries of transport. Wide variety of ITS applications is a real opportunity for development of movement in the future. Today’s intelligent transport systems products and services in EU are based on telecommunication, electronic, and information technology. A wide range of new applications represents a real revolution in transport. In our paper we would like to analyse road traffic accident rate in the Slovak Republic as one of the main externalities, and the possibilities of decreasing them with the assistance of telematics applications.
