Improving the organization of traffic at an intersection with traffic lights through simulation modelling and assessment of the possibility of converting into a roundabout

Abstract This paper investigates the possibilities for improving the traffic organization at a traffic light-controlled intersection in urban conditions through simulation modelling and evaluation of a potential alternative - conversion to a roundabout. By comparing scenarios with the existing state, optimized traffic light control and a design proposal for a roundabout, the effects on throughput, average delay and safety are established.
