The Engineering Division has received a request 0 from VPA to install a multi -way stop at this intersection. This memo summarizes the warrant analysis conducted to assess the need for a permanent all -way stop at this intersection and the proposed recommendation. Location/Description. Both Lafayette Boulevard and Riverside Drive are classified as local streets, and both have one travel lane per direction. Warrants The Manual on Uniform Traffic Control Devices sets forth the following requirements to warrant the installation of multi -way stop control: The following criteria should be considered in the engineering study for a multi -way STOP sign installation: A. Where traffic control signals are justified, the multi -way stop is an interim measure that can be installed quickly to control traffic while arrangements are being made for the installation of the traffic control signal. B. Five or more reported crashes in a 12-month period that are susceptible to correction by a multi - way stop installation. Such crashes include right -turn 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 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 minor -street vehicular traffic of at least 30 seconds per vehicle during the highest hour; but We deliver services that empower everyone to thrive!!
