Urban interchanges contain both saturated traffic flow and unsaturated traffic flow. Their traffic characteristics are significantly different from signalized intersections and unsignalized intersections. On the foundation of iterative observation and research of traffic flow characteristics of a Beijing cloverleaf interchange, this paper puts forward a study on urban cloverleaf interchanges. Traffic flow at urban interchanges is unique; combining actual data and calibration, researchers used the VISSIM simulation model to calculate the capacity of the Anhua Bridge. The capacity of the whole interchange is analyzed by simulation experiments, and the relationship between the whole interchange capacity and the turning vehicle proportions is put forward; with the increase of turning vehicle proportions, the whole traffic capacity of the interchange decreases constantly. The conclusion can be used for decision-making on planning, design, and management.
