Simulation of the four-way and two-way stop sign controlled intersections

The analytical complexity of most automobile traffic intersections strongly directs the researcher to simulation as his tool of analysis. This tool, through the General Purpose Systems Simulation language (GPSS), was used in a recent investigation of two different stop sign controlled intersections. On the basis of a comprehensive literature search, the authors feel that the simulation models reflect, as nearly as is presently possible, the “real-life” situations. This paper, an out-growth of that investigation, includes discussions of: (1) basic assumptions of the models, (2) empirical probability distributions employed, (3) comparisons for a selected objective function, (4) comparisons of the models with existing literature, and (5) conclusions and recommendations for further research.
