I Multiway Stop Sign Warrants Intersection: ' Analyzed,by: Study Date: 1 Multiway stop control can be used as a safety measure at intersection if certain traffic conditions exist. Safety concerns associated with multiway stops include pedestrians, bicyclists, and all road users expecting other road users to stop. ' Multiway stop control is used where the volume of traffic on the intersecting roads is approximately equal. The following criteria should be considered in the engineering study for a multiway STOP sign installation. ' A. Where traffic control signals are justified, the multiway stop is an interim measure that can be installed quickly to control traffic while arrangements are beingmade for the installation of the traffic control signal. B. A crash problem, as indicated by 5 or more reported Crashes in a 12 month period that are susceptible to Correction by a multiway stop installation. Such Crashes include right- and left- turn collisions as well as right -angle collisions. C. Minimum volumes: 1. The vehicular volume entering the intersection from the major street approaches (total of both approaches) averages at least 300 vehicles per hour for any 8 hours 1 of an average day, and 2. The combined vehicular, pedestrian, and bicycle volume ' Entering the intersection from the minor street approaches (total of both approaches) averages at least 200 units per hour for the same 8 hours, with an average delay to the minor street vehicular traffic of at least 30 seconds per vehicle during the highest hour, but 3. If the 85th percentile approach speed of the major street 1 traffic exceeds 65 km /h (40 mph), the minim vehicular volume warrants are 70 percent of the above values. ' D. Where no single criterion is satisfied, but where Criteria B, C.1, and C.2 are all satisfied to 80 percent of the minim Values. Criterion C.3 is excluded from this condition.
