Circulating Geometry

Circulating Geometry
The Circulating Geometry has three parameters
Diameter D
The diameter D is the outer diameter or Inscribed Circle Diameter.
Circulating Width C
The circulating width only affects capacity as it defines the number of circulating streams so neither the HCM nor the geometric capacity models use C for capacity estimation directly. C only affects capacity if it changes the number of circulating traffic streams.
Circulating Lanes nc
This section must be read in conjunction with the one above on circulating width C.
