Increasing the Efficiency of the Functioning of an Unregulated Intersection with Circular Traffic

Abstract

The analysis and empirical studies of conditional and unconditional parameters of the traffic model at an unregulated intersection with circular traffic in the city of Ternopil were conducted. The intersection "Zbarazke ring" in the city of Ternopil is an unregulated intersection with a circular traffic pattern and is located at the intersection of Stepan Bandera avenue, April 15 street, T. Protasevich street and Pidvolochyskyi highway. To verify the effectiveness of the proposed solutions, simulation models of the intersection "Zbarazke ring" with the existing and proposed traffic management system were created. The conducted traffic modeling using multi-parameter models made it possible to take into account various options for road infrastructure, restrictions and traffic parameters, which made it possible to justify optimal decisions regarding the improvement of the organization of traffic at the object of study. Five variants of traffic organization at the intersection with circular traffic are proposed, the best of them is modeled, analyzed and substantiated, and ways to improve the quality of functioning of this section of the street-road network are proposed. According to the results of the simulation modeling of the intersection "Zbarazke ring", the implementation of the proposed measures will lead to the following improvements compared to the existing traffic conditions at the intersection: the average speed of vehicles will increase by 30%; the average delay time will decrease by 28%; the average number of road transport stops will decrease by 21%; the average time spent in traffic jams will decrease by 50%.
