Partial cloverleaf interchange - Wikipedia
A partial cloverleaf interchange or parclo is a modification of a cloverleaf interchange. The design has been well received, and has since become one of the most popular freeway-to-arterial interchange designs in North America.
Cloverleaf interchange - Wikipedia
A cloverleaf interchange is a two-level interchange in which all turns are handled by slip roads. To go left (in right-hand traffic; reverse directions in left-driving regions), vehicles first continue as one road passes over or under the other, then exit right onto a one-way three-fourths loop ramp (270°) and merge onto the intersecting road.
Interchange (road) - Wikipedia
A partial cloverleaf interchange (often shortened to the portmanteau, parclo) is an interchange with loops ramps in one to three quadrants, and diamond interchange ramps in any number of quadrants. The various configurations are generally a safer modification of the cloverleaf design, due to a partial or complete reduction in weaving, but may ...

Mar 8, 2016 · Traditional interchanges including the cloverleaf, partial cloverleaf (Parclo), and the directional interchange require large right-of-ways and are costly and often difficult to construct in urban environments.
This spreadsheet implements the crash prediction models for diamond, compressed diamond, roundabout diamond, diverging diamond, single-point diamond, tight diamond, and partial cloverleaf (parclo) interchanges.
Designing Complex Interchanges - FHWA
Many complex interchanges, such as Milwaukee's Marquette Interchange, shown here, are located in metropolitan areas where reconstruction is difficult and complex. Four key issues for interchange designers' attention are ramp spacing, guide …

A cloverleaf interchange has eight ramps, as does a stack interchange. They are fully grade separated, unlike a parclo, and have traffic flow without stops on all ramps and throughways. A parclo generally has either four or six ramps but less commonly has five or seven ramps.
