This study examines the perspectives, acceptability, and perceptions of road users on the newly constructed modern roundabouts in the medium-sized urban city of Volos, Greece. The objective is to assess the performance of these recently installed roundabouts in comparison to the prior signalised intersections in terms of traffic flow, safety, and acceptance among the city′s population. In order to accomplish this objective, a questionnaire survey was developed and thereafter, a representative sample was chosen. In total, there were 189 responses. Data were collected during this process and subsequently assessed and appraised using statistical analysis techniques. The primary finding of the current study is that road users exhibit a high level of acceptance of roundabouts. In particular, 90% of people strongly support the use of roundabouts and believe that they significantly improve traffic flow. Nevertheless, the perceived levels of safety are not totally sufficient, as 50% of pedestrians expressed a sense of insecurity. The binary logistic regression model revealed that gender, rate of travel through a roundabout in the city, and positive opinions towards the safety impacts of roundabouts were the primary variables influencing public acceptance of roundabouts.
