A New Minimum Delay Model for Multi-Lane Traffic Circles

Minimum delay (or service delay) is one of the most important performance measures for intersection analysis. It can be described as to a vehicle, which waiting at stop yield) line an unsignalized intersection. In this study, appropriate minimum equation derived multi-lane traffic circles in İzmir, Turkey. For purpose, observations are made six approaches five circles. Simple and multiple regression analysis, circulating flow geometric parameters chosen independent variables, used model delay. Results have shown that geometry circle has effect on should considered analysis but may fail define values greater than 22 seconds. Analyses models depend entry capacity more effective estimation
