From page 120...
... The best-fitting curve, the Akcelik equation, has about a 40% better RMS error than the standard BPR equation. MODEL SPEED–FLOW EQUATION CALIBRATION -- V/C > 1.00 The field data could not be used to evaluate the speed–flow curve candidates for demands greater than capacity because the standard traffic counting procedure used could only count the served demand, not the unserved demand.
