The authors present a simple model of a four-way-stop-sign controlled intersection. Computer runs from a simulation model help to generate a majority of the statistics on volumes and delays at a one-lane approach (two-by-two) intersection (which constitutes the simplest case of all possible four-way-stop configurations). These runs were based on field tested with observations gathered at five intersections in various part of Washington State and northern Idaho (representing the largest data set reported in the literature, including the two intersections in the metropolitan Washington, D.C., area used to calibrate the simulation program). Using these data and the expanded database generated from discrete-event simulation, a regression model (or response surface) was calibrated to explain average vehicular delay at such intersections in terms of volume split, percentage of left-hand-turns, and traffic volume in general. The response-surface model wad independently validated by another (the sixth) field test in southwestern Washington State. This analysis approach is, in the authors' judgment, more promising than other methods used to date.
