COMPARISON OF TRAFFIC DENSITIES AT DIFFERENT SIGNALIZATION TIMINGS IN ROUNDABOUTS
Öz
The increasing number of vehicles triggers traffic jam which is one of
the most important problems that occurs in crowded cities. Signalization timing
has a crucial role in controlling traffic flow and decreasing loss of time in
city traffic. In order to reduce queue length and vehicle delays in traffic,
the estimation of traffic concentration at different signalization timings
plays an important role. Traffic simulation tools such as RODEL, SIDRA, and VISSIM are used to understand the behavior of vehicles in traffic. In this study,
VISSIM program was used to demonstrate queue lengths, vehicle delays and
vehicular emission formations in a roundabout at different signalization
timings. The study has been evaluated on a real case study to verify the
differences between current and proposed states. A roundabout in Adana (Turkey)
was selected which is located at the city
center with over-saturated traffic density for a case study. The model indicated that increment of the green time period of the south road from 22 seconds to 28 seconds resulted in improved queue lengths, vehicle
delays and emission formations of the vehicles which were around the
roundabout.
