Özet
The increasing number of vehicles triggers traffic jam which is one of the most important problems that occursin crowded cities. Signalization timing has a crucial role in controlling traffic flow and decreasing loss of time incity traffic. In order to reduce queue length and vehicle delays in traffic, the estimation of traffic concentration atdifferent signalization timings plays an important role. Traffic simulation tools such as RODEL, SIDRA, andVISSIM are used to understand the behavior of vehicles in traffic. In this study, VISSIM program was used todemonstrate queue lengths, vehicle delays and vehicular emission formations in a roundabout at differentsignalization timings. The study has been evaluated on a real case study to verify the differences between currentand proposed states. A roundabout in Adana (Turkey) was selected which is located at the city center with oversaturated traffic density for a case study. The model indicated that increment of the green time period of thesouth road from 22 seconds to 28 seconds resulted in improved queue lengths, vehicle delays and emissionformations of the vehicles which were around the roundabout.
