DIAMOND INTERCHANGE TRAFFIC CONTROL. VOL 5. BEFORE AND AFTER SIMULATIONS AND FIELD STUDIES OF DIAMOND INTERCHANGE OPERATIONS

A set of field experiments was conducted to check out the generality of prediction of SDC-developed digital computer simulation models of signalized diamond interchange traffic operations. The simulation models were first validated by comparing the simulation outputs to field-obtained operational performance data (using aerially-collected time-lapse photography). The model validation was performed for two distinct diamond interchange facilities. No significant differences were observed between the simulation and field-obtained results. The next step in the process was to predict the operational performance at a selected diamond interchange for which a set of improved signal timing parameters were computed using a set of SDC-developed signal control algorithms. These new parameter values were introduced into the simulation models, where a prediction of improved operational performance was obtained. /Author Modified Abstract/
