abstract="A study is reported which compared all-way stop sign control with traffic signal control. The signal operations studied included pretimed control, actuated control, 3-phase operation, and 4-phase operation with overlaps. Details of the study and results are given, and conclusions drawn from the study which apply to diamond interchanges formed by either 1-way frontage roads or 1-way ramps intersecting a cross street are presented. It is noted that a diamond interchange operates very differently from two isolated intersections because of close spacing. Because diamond interchanges operate differently from isolated intersections, criteria for warranting diamond interchange signalization should be a separate MUTCD (Manual on Uniform Traffic Control Devices) procedure from that for single isolated intersections. Diamond interchange models that uniquely combine the complex interactions of internal and external traffic appear to be the most representative approach on which to base diamond interchange guidelines for signalization. A discriminating diamond interchange volume level exists, beyond which traffic signal control is better than stop sign control.<p />",
