Popis:	Signalized diamond interchanges are unique pairs of intersections characterized by interlocked left turns and relatively close spacing between ramps. A diamond interchange has four external entry points (origins) and four external exit points (destinations). Examination of the external origin–destination paths and evaluation of their impact on the interior storage and progression are critical for operating a diamond interchange effectively. This paper describes a series of performance measures derived from high-resolution signal controller data that can be used to (a) assess the quality of progression of the interior movements qualitatively and quantitatively and (b) optimize the internal offset to improve traffic flows within the interchange. Additional performance measures for identifying internal and ramp queuing are discussed. The integration of graphical performance measures into controller front panel displays and central systems is recommended to assist engineers in tuning and maintaining efficient operation of diamond interchanges.
