A DIGITAL SIMULATION MODEL OF A FREEWAY DIAMOND INTERCHANGE

摘要

The Vehicular Traffic Study Project at System Development Corporation has developed a digital computer simulation model of a portion of a freeway diamond interchange. The total model will be designed for conducting research promoting the improvement of the geometric designs of freeway interchanges and for the development of effective control devices regulating traffic flow through them.nIncluded is an outline of the four phases of the study being conducted, and a description of the first phase, or Model 1, which has been formulated and coded for a digital computer. The programming components of Model are given, together with the various outputs produced by the data reduction routines. The paper concludes with an indication of the future directions to be taken in this study.
