Roundabout, computer simulation, traffic rules

This article presents a new roundabout simulator developed at the Faculty of Computer Science and Information Technology of the West Pomeranian University of Technology in Szczecin, designed to study traffic flow in terms of differently defined rules. The essence of creating the simulator was to check whether the traffic rules prevailing at roundabouts are correct (unfortunately, in many cities they are interpreted differently due to imprecise provisions in the Highway Code) and whether their modification can contribute to greater capacity of such intersections. In the first part of the article, the author describes the developed simulator from the user’s perspective, i.e., the tool’s capabilities, the method of defining an intersection, the method of data entry, setting traffic flows, choosing traffic rules, etc. Next, the author presents the characteristics of a selected roundabout in Szczecin (including traffic distribution relative to individual roads) and conducts an appropriate analysis based on it.SOFTWARE ROUNDABOUT SIMULATOR TO STUDY THE TRAFFIC RULES
Abstract
This paper presents a new, developed at the Department of Computer Science and Information Technology in WestPomeranian University of Technology, a roundabout simulator, designed to test the traffic flow in terms of different defined rules. The essence of the simulator’s creation was to examine whether the prevailing rules of the road at roundabouts are correct (unfortunately, in many cities interpreted differently because of unclear wording in Polish
Highway Code) and if its modification may contribute to greater bandwidth such intersections. In the first part of the article the author describes the developed simulator, a kind of the user-manual: the possibility of the tool, a way of defining crossroads, a data input, setting the traffic flows, the choice of traffic rules, etc. Then, author presents the characteristics of the selected Szczecin’s roundabout (i.a. the distribution of traffic to the different routes) and on the basis of that leads appropriate analysis.
