A Study of Four-Way Stop Intersections: The Validation of a Delay Model
Abstract
The four-way stop intersection is a controversial method of traffic control but it has seen limited research and existing guidance is not specific. Richardson developed a delay model to predict average time in the system at four-way stop intersections but he does not validate it with field data. This shortcoming is investigated here by taking field measurements to evaluate the accuracy of the model predictions. The results support the accuracy of the model. Using a current value for minimum allowable headway improves the accuracy of the model predictions. This study also looks at how and why four-way stops are used in the field through interviews with practicing engineers.
