3. When the highest 8-hour approach volume (total of both approaches) on the minor <br />street is greater than 30% of the total volume on all approaches for the same 8 hours, <br />and the total 8-hour approach volume for all approaches averages at least 250 <br />vehicles per hour, and no other stop sign or traffic signal on the major street is <br />located within 800 feet; <br /> <br />4. When 3 or more accidents of types correctable by all-way stop control have <br />occurred at the intersection within a recent 12-month period; for intersections <br />within 800 feet of a school (K-12), the threshold is 2 or more accidents; <br /> <br />5. When land uses within 800 feet of the intersection generate 40 or more pedestrians <br />crossing the major street during one hour on a typical weekday, and no preferable <br />crossing point (as determined by the Traffic Engineer) is located within 800 feet; <br /> <br />6. Sight-distance on vehicular or pedestrian crossing approaches is less than 150 feet; <br /> <br />7. Other non-engineering criteria as adopted by the City Council on a case-by-case <br />basis; for example, a nearby school, playground, park, senior center, public facility, <br />or other land use generating pedestrian or bicycle activity that merits additional <br />protection from vehicle traffic; <br /> <br />And <br />B. An engineering study performed to evaluate conformance to these warrants has <br />determined no alternative measures are more appropriate to address the identified traffic <br />concerns, and that installation of all-way stops is compatible with the overall traffic <br />considerations for the area. <br /> <br />For two-way stops (and one-way stops on streets terminating at an intersection) the warrants in <br />the Traffic Manual apply on residential streets. <br /> <br />Advantages/Other Considerations: Readily understood. Can be installed quickly and <br />inexpensively. Ineffective as speed control device except within 200 feet of intersection (where <br />it also has the undesired effect of increasing traffic noise). May have some effect on midblock <br />speeds of the very fastest drivers, while not affecting midblock speeds of the vast majority of <br />drivers. Ineffective as a traffic diversion device except where travel time using the short-cut <br />route through the neighborhood offers only a small advantage over the travel time using the <br />more appropriate route. <br /> <br />Alternate Devices: For right of way control: yield sign, traffic signal, occasionally circles. For <br />speed control: traffic circle, undulations, enforcement preferable. Diverters, semi-diverters, <br />cul-de-sacs, median barriers, turn prohibitions and channelizations are preferable as diversion <br />devices. <br /> <br />Cost (Typical): $2000 per intersection for 2-way STOP; $4000 per intersection for 4-way. <br /> <br /> <br />6.3.A. - Page 6
