Traffic Modelling of the Circular Junction in the City of Žilina

Nowadays, a high-quality road network is necessary for sustainable transport systems. A sharp rise in automation results in increased transport problems. The most serious problems include the traffic infrastructure congestion, congestion, and increased risk of a traffic accident and, of course, a negative impact on the environment. The mobility of inhabitants and the transport of goods are one of the key transport objectives. A junction still constitutes the most critical point on the road network. That is why crossing the road smoothly and safely makes a large difference for the vehicle. This article provides an analysis of the current state of the selected circular junction. On the basis of the conducted survey, new solutions for this junction were presented, which should prevent the traffic conditions from becoming obtrusive. The Aimsun microsimulation was performed for checking the new proposals.
