TRAFFIC INPUTS FOR SIMULATION ON A DIGITAL COMPUTER

THE RELATIVE MERITS OF OBSERVED INPUTS AND GENERATED INPUTS ARE DISCUSSED. IT IS POINTED OUT THAT WHERE GENERATED INPUTS CAN BE USED, THEY HAVE A DECIDED ADVANTAGE FROM THE STANDPOINT OF COMPUTER TIME. A METHOD OF GENERATING POISSON INPUTS IS DESCRIBED. SEVERAL SETS OF INPUTS HAVE BEEN GENERATED BY THIS METHOD AND TESTED STATISTICALLY. THE RESULTS OF THESE ARE GIVEN. TIME SPACINGS OF VEHICLES ENTERING A SYSTEM ARE APPROXIMATELY EXPONENTIAL. METHODS OF ADJUSTING THE EXPONENTIAL TO OBTAIN GREATER REALISM ARE DISCUSSED. METHODS OF COMPUTER GENERATION ARE DISCRIBED. /AUTHOR/
